The Committee on Underground Waters for the new triennium is composed of the following: H. F. Blaney; E. B. Burwell; W. Gardner; C. S. Howard; F. H. Lahee; G. W. Musgrave; A. M. Piper; A. C. Swinnerton; L. K. Wenzel; D. G. Thompson (Chairman).
The outstanding event of the year for ground‐water hydrologists was the meeting of the International Association of Scientific Hydrology, as a part of the International Union of Geodesy and Geophysics, at Washington, D.C., in September, 1939. One day was devoted to “questions” or topics of symposia of the Commission on Subterranean Water.

The Committee represents a rather wide geographic distribution, quite a large variety of interests, and most of the agencies interested in runoff‐problems.
Throughout the year members of the Committee have shown interest in runoff‐problems of various kinds as evidenced by numerous articles and discussions in technical publications and by their participation in the deliberations of many working or advisory committees dealing with hydrologic problems. As the Chairman views it, the functions of the members of the research committees are not only to keep abreast of, and to make advances in, the technique relating to their particular fields, but also to demonstrate the practicability of the technique in the field of applied hydrology. Members of the Committee on Runoff have kept these aims in view. As in past years, the Committee is indebted to Miss Mary Soroka of New York City, Chairman of the International Committee on Bibliography, for her compilations of references to all articles relating to runoff, and to Mr. Beij for his work in connection therewith.

These four subsections comprise the land forms produced \nby the Mokelumne River and other streams since the Sierra Nevada attained its \npresent height in the Pleistocene epoch. \nThe Victor alluvial plain rises eastward from the Delta plain and abuts on the \ndissected Arroyo Seco pediment; in the Mokelumne area it is 12 to 16 miles wide \nand slopes between 5 and 8 feet in a mile. It includes relatively extensive tracts \nthat are intensively cultivated and irrigated with water pumped from wells. The \nVictor plain has been compounded of overlapping alluvial fans along the western \nbase of the Sierra Nevada. It is prolonged eastward into the pediment by tongues \nof alluvium along several of the present streams; thus it seems likely that the \npresent stream pattern in the eastern part of the area has been fixed since dissection of the pediment began. \nThree of the four major streams-the Mokelumne and Cosumnes Rivers and \nDry Creek-traverse the Victor plain in trenches which are 15 to 40 feet deep \nat the heads of their respective alluvial fans but which die out toward the west. \nThe floors of these trenches, the historic flood plains, are from 100 yards to a mile \nwide. The exceptional major stream, which has not entrenched itself, is the \nCalaveras River. \nThe Arroyo Seco pediment, which lies east of the Victor plain, was initially at \nleast 8 to 15 miles wide and lay along the western foot of the Sierra Nevada entirely \n.across the Mokelumne area. Its numerous remnants decline 15 to 35 feet in a \nmile toward the west. \nThe Sierra Nevada section adjoins and lies east of the California Trough. Its \nmajor ridge crests define a volcanic plain whose westward slope is' inferred to have \nbeen initially about 90 feet in a mile but is now about 180 feet in a mile, owing to \ntilting of the Sierra Nevada block in Pleistocene time. \nIn and near the Mokelumne area the Sierra Nevada and California Trough \ntogether are roughly coextensive with a single structural unit. The Sierra \nNevada constitutes a block that has risen with respect to adjoini;ng valley areas \n'by simple rotation or tilting toward the west; it has not been warped or faulted \n-extensively. It is inferred that this block extends westward beneath the thick \nalluvial deposits of the trough without material warping or faulting. \nThe oldest rocks of the Mokelumne region are the Carboniferous and Jurassic \n-rocks that compose the crystalline core of the Sierra Nevada. These are overlain \nunconformably by sediments of Tertiary age--in upward succession the lone, \nValley Springs, Mehrten, and J.Jaguna formations. Of these formations all except \nthe lone are newly discriminated, and type sections are described in the full text. \nThese Tertiary sediments form a great wedge, thinnest along the mountain front \nto the east, where they have been truncated by erosion. They dip about 2° W. \nThe lone formation (Eocene) consists chiefly of sandstone, clay, and shale; its \nmaximum thickness is 450 feet. \nThe Valley Springs formation (middle? Miocene) overlies the lone formation \nunconformably. It is composed largely of greenish-gray clay, shale, and sandstone derived from rhyolitic ejectamenta. These rhyolitic deposits are confined \nto narrow channels in the higher part of the Sierra Nevada, but they \nspread fanlike over the lower western edge of the mountain block, where they \nattain a maximum thickness of 525 feet. \nThe Mehrten formation (upper? Miocene and lower Pliocene?) comprises the \nandesitic rocks that constructed the Sierran volcanic plain. In the Mokelumne \narea it consists chiefly of sandstone and siltstone but includes, as a minor though \nconspicuous part of the formation, layers and tongues of resistant breccia or agglomerate, which are presumed to have originated as mud flows. Nonfragmental \nandesite is not known to occur in the Mokelumne area, although several possible \nvents occur farther east. In the eastern part of the area the Mehrten formation \ntruncates in turn the Valley Springs and lone formations and the pre-Cretaceous \nrocks; in the western part the Mehrten formation (andesitic) interfingers with the \nunderlying Valley Springs formation (rhyolitic). Its maximum measured thickness is 400 feet. Few of the irrigation wells are so deep that they can be said \nwith assurance to reach the Mehrten formation. \nThe Laguna formation (Pliocene? and possibly lower Pleistocene) comprises \npoorly sorted, nonandesitic fluviatile sedimentary that overlie the \nMehrten formation. It is inferred to be essentially parallel to and tilted equally \nwith the Mehrten formation and to be about 400 feet thick. \nThe Arroyo Seco gravel (presumably middle Pleistocene) veneers the Arroyo \nSeco pediment. At its easternmost outcrops the formation is composed of \npebbles, cobbles, and boulders in a matrix of brick-red sand and silt; farther west, \ndown the slope of the pediment, it becomes pr9gressively finer. It is inferred \nthat the Arroyo Seco gravel is a coarse fraction of the rock waste that was transported from the Sierra Nevada after the Sierran.block was tilted in Pleistocene \ntime. It is inferred further that the correlative of the Arroyo Seco gravel in the \nCalifornia Trough is a wedge-shaped mass of sediments whose base is the \ntilted Laguna formation and whose top can be interpolated by projecting a \nhypothetical surface through the remnants of the pediment. \nThe Victor formation comprises the fluviatile sand, silt, and gravel that built \nthe Victor alluvial plain over the hypothetical equivalent of the Arroyo' Seco \ngravel along the axis of the California Trough and against the western front of \nthe dissected pediment to the east. The formation is thought to be about 100 \nfeet thick along the western margin of the Mokelumne area, according to an \nestimate based upon projecting the slope of the Arroyo Seco pediment westward \nbeneath the Victor plain. \nThe Mokelumne area lies on the fertile central plain along the Mokelumne \nRiver about the city of Lodi, in northern San Joaquin County, and has been \nintensively developed for the cultivation of grapes, deciduous fruits, and other \ncrops. Of necessity its great productiveness is maintained by irrigation. Extensive irrigation from wells began about 1907 and has increased steadily until in \n1932 about 50,000 acres (80 percent of the area) was watered in that manner. \nThe specific question at issue is the extent to which the supply of ground water \nand hence the productiveness of the area are dependent upon the water flowing \nin the Mokelumne River and the extent to which that productiveness may be \ninfluenced by regulation of the stream--:in particular, by the substantial regulation of the river that is accomplished by the Pardee Dam of the East Bay Municipal Utility District, which began to function in March 1929. \nThe depth of 1,447 irrigation wells in five townships in the central part of the \narea (T. 3 N., Rs. 6 and 7 E., and T. 4 N., Rs. 6 to 8 E.) ranges from 20 to 910 \nfeet. About half the wells bottom within a 100-foot zone whose base is 75 feet \nbelow the projected Arroyo Seco pediment; essentially that zone constitutes the \nVictor formation. Only 6 percent of the wells bottom within the next lower 25-\nfoot zone, but the percentage increases sharply for depths still greater; it is inferred \nthat impervious strata are relatively persistent between 75 and 100 feet below \nthe projected pediment and that these are the uppermost part of the Arroyo Seco \ngravel. Of 580 observation wells known to bottom in the Victor formation, essentially all appear to indicate a regional water-table stage; thus the water is essentially unconfined. On the other hand, nearly all wells so deep that they reach the \nArroyo Seco gravel or some underlying formation tap confined water. Near the \nMokelumne River the water levels in these deep wells stand below the water \ntable, which is semiperched. In most deep wells remote from the river the water \nlevel stands above the water table except during the pumping season. \nFluctuations of ground-water levels are ascribed to moving or changing load on \nthe land surface, earthquakes, variation of barometic pressure, ground-water \ndraft by vegetation, infiltration of rain and certain indirect effects of rainfall, infiltration of water applied to the land for irrigation, variation in the discharge of \nstreams, and pumping from wells. \nIn the eastern part of the central district, between Clements and the vicinity of \nLockeford, it is inferred that (1) the river and the water in the alluvium of the \nflood plain are not insulated from the water in the sediments that form the adjacent Victor plain; (2) locally if not generally, however, there are discontinuities \nin pervious strata along the outer margin of the flood plain, where the water table \npasses from the alluvium into the enclosing sediments, so that percolation of \nground water is impeded materially at that margin; (3) rising river stages set up \nground-water waves that store relatively large volumes of water in the alluvium \nclose to the river, whereas falling stages cause much of that stored water to percolate back into the river, weeks and even months lapsing before the ground-water \nstage becomes steady within the flood plain; and (4) seepage loss from the river \ninto the alluvium tends to be intermittent and to alternate with seepage gain, the \nrate of loss or gain lagging weeks or months behind the fluctuations of river stage \nand lagging more for moderate changes at low stage. However, in the succeeding \nreach downstream as far as Woodbridge, it is inferred that percolation of ground \nwater is not impeded generally along the outer margin of the flood plain and that \nthe river tends to lose almost continuously by seepage rather than intermittently, \nalthough the rate of loss fluctuates somewhat in response to changing river stage. \nThe yearly pumpage for irrigation has been as much as 114,600 acre-feet (1928-\n29), and there have been as many as 2,500 wells equipped with irrigation pumping plants (1931). Commonly the wells are pumped only in daylight and are \nidle over week-ends and holidays, also during and after protracted rainstorms in \nthe early part of the season. In a small district near Victor pumping in recent \nyears has begun in January or February, has reached its height in March, and \nlargely has passed by April. In outlying districts general pumping has begun as \nlate as May, reached its height in June or July, and waned by September. \nSince 1907 the water table appears to have declined steadily in most of the \nMokelumne area except along the river. The decline was least in the Woodbridge Irrigation District, where in four typical wells. the average decline from 1907 \nto 1937 was 3 feet, or 0.15 foot a year. Among 18 shallow wells in the district of \nmost intensive pumping the average recession of the water table from 1907 to 1927 \nwas 11 feet, or 0.55 foot a year; the greatest measured recession was 15 feet, or \n0.75 foot a year. From 1927 to 1933 the water table declined 5 feet or more over \nmost of the central pumping district except within 2 miles of the Mokelumne \nRiver, and the greatest measured decline was 9 feet. The area of material \nrecession ,extends 4 to 7 miles eastward beyond the central pumping district, \nwhence it is inferred that pumping has drawn gradually on remote ground-water \nstorage. \nIt is inferred that the Mokelumne River ordinarily has been a losing stream \nbetween the Mehrten dam site, near Clements, and the Woodbridge Dam, the \narea that received the percolate having been triangular with its upstream \nand having included about 5,200 acres of the flood plain and 36,500 acres in outlying districts to the north and to the south. \nMean fluctuations of the water table within the area receiving percolate from \nihe river are believed to indicate that relatively little water is drawn from outside \nthe area. Accordingly, simple storage methods are competent for a ground-water \ninventory. It is inferred that the rate of seepage loss from the river depends \njointly upon river discharge, stage in the Woodbridge Reservoir, and groundwater pumpage. \nThe foregoing inferences lead to the following conclusions with respect to \nground-water replenishment by seepage loss from the river in the intensively \ncultivated district about Lodi: (1) The annual replenishment has tended to increase \nfor at least two decades, owing to the gradual increase in head between surface \nwater and ground water as ground-water levels have been lowered progressively \nby pumping; (2) annual replenishment has tended to increase, especially in recent \nyears, owing to gradually prolonged use of the Woodbridge Reservoir, for thereby \na relatively large wetted area and great differential head have been maintained \nfor an increasing term; (3) the rate of replenishment tends to be greater under \nregulation than under the so-called natural regimen, to the extent that regulation \nhas maintained a moderately large wetted area and stage in the river through \nthe later part ·of each pumping season, whi1e the ground-water levels have been \nlowest. Moreover, for any particular yearly run-off below the Mehrten dam site, \nthe replenishment by seepage would tend to be greater under the regulated \nregimen to the extent that fluctuations in discharge were suppressed, for the \ngreatest yearly mean stage and mean wetted area would be afforded by constant \ndischarge. -Thus, diverting water out of the Mokelumne River Basin at the \nPardee Dam does not necessari1y-entail a diminution in ground-water replenishment by seepage loss along the lower reach of the stream, at least in the replenishment beneath the Victor plain above the gaging station at Woodbridge. Rather. \nthe Pardee Dam affords a means for so regulating the discharge as to effect a \nmaximum ground-water replenishment with-a given run-off in the natural channel. \nBodies of ground water perched above the regional water table are common in \nthe Laguna formation, especially in its lower part. Conspicuous bodies occur \nabout 3 miles south of Clay, in a district between 1 mile and 5 miles south of \nClements, and along Dry Creek in T. 5 N., Rs. 7 and 8 E. \nFrom the relation between the water table and the piezometric surface for water \nconfined in deep aquifers, the area receiving percolate from the Mokelumne River \nmay be divided roughly into (1) a central area, extending not :p1ore than half a \nmi1e beyond the flood plain, in which the piezometric surface is inferred to have \nstood below the water table throughout the term of the investigation and hence \nin which the difference in head has favored the percolation of water from shallow \nbeds into deep beds in all seasons, and (2) an outlying area in which the difference \nin head likewise favors downward percolation into deep beds during the pumping \nseason but favors upward percolation during the nonpumping season. This outlying area includes about 75 percent of the segment of the Victor plain that receives percolate from the river. \nFrom 1927 to 1933 the subartesian head that existed during the nonpumping \nseason in the area remote from the river tended to increase; it is therefore inferred \nthat the relative opportunity for seasonal recharge of the shallow water-bearing \nbeds by underfeeding has likewise tended to increase. On the other hand, the \nnegative differential head in wells near the river also has tended to increase; thus \nin this central area the opportunity for discharge of water from shallow beds by \ndownward percolation has probably tended to increase. \nIt is believed that ground-water storage within the area near the river is not \ndecreased materially by\" discharge westward through deep pervious beds, also \nthat the yearly addition to ground-water storage in the outlying area by deep \npercolation from a remote easterly source is scant and for all practical purposes is \noffset by downward percolation along the river.","language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington","doi":"10.3133/wsp780","usgsCitation":"Piper, A.M., Gale, H.S., Thomas, H.E., and Robinson, T.W., 1939, Geology and ground-water hydrology of the Mokelumne area, California: U.S. Geological Survey Water Supply Paper 780, Report: vii, 230 p.; 8 Plates: 52.32 x 43.46 and smaller, https://doi.org/10.3133/wsp780.","productDescription":"Report: vii, 230 p.; 8 Plates: 52.32 x 43.46 and smaller","numberOfPages":"257","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":138771,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/0780/report-thumb.jpg"},{"id":278843,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/0780/plate-10.pdf"},{"id":278841,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/0780/report.pdf"},{"id":278842,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/0780/plate-09.pdf"},{"id":277927,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/0780/plate-08.pdf"},{"id":28624,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/0780/plate-01.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":28625,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/0780/plate-02.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":28626,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/0780/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":28627,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/0780/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":28628,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/0780/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"500000","country":"United States","state":"California","otherGeospatial":"Calaveras River;California Trough;Cosumnes River;Dry Creek;Mokelumne River;Sierra Nevada","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.5,37.5 ], [ -122.5,39.25 ], [ -119.5,39.25 ], [ -119.5,37.5 ], [ -122.5,37.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adce4b07f02db6864a1","contributors":{"authors":[{"text":"Piper, A.

Since the beginning of the science of hydrology attempts have been made to interpret these phenomena and determine their significance. On the basis of actual observations and “with special reference to Long Island, New York,” Veatch [see 1 of “References” at end of paper] in 1906 considered in some detail several different causes of water‐level fluctuations. He placed the known causes under two general headings, natural and human. However, considering proximate rather than ultimate causes a further classification might be, and indeed often is, made with regard to the conditions under which the fluctuations are produced by a given agency, natural or human. Thus we speak of ”water‐table conditions“ and ”artesian conditions,“ realizing, however, that the distinction between the two is not always definite. The phenomena peculiar to artesian conditions are usually the result merely of the imperviousness of the confining beds relative to the particular aquifer under consideration. Indeed, it is recognized that perhaps even the most dense clay is not absolutely impervious to the flow of water, given a difference in head, sufficient to produce the flow, though it may be beyond the precision of the means now employed to detect the flow of water through such impervious strata.

For this reason, the question as to the definitions of different kinds of subterranean water was selected as one of the three questions for discussion by the International Commission on Subterranean Water at the meeting in Edinburgh in 1936 and again (as Question No. 2) at the meeting that is to be held in Washington in September, 1939.
The purpose of the International meetings is not only to discuss subjects of mutual interest but also, so far as practicable, to make official decisions. Obviously, decisions on scientific questions should be made only after mature consideration and only on questions as to which there is general agreement. The reports that have been prepared in different countries on the question under consideration and the correspondence and oral discussion appear to show that the way is open for International agreement on some of the basic concepts. A comprehensive paper on the question was prepared for the Edinburgh meeting by Dr. Vasillevskij, of Russia (Internat, Ass. Sci. Hyd., Bull. 22, 1936). Dr. Yasilievskij, in a letter dated January 12, 1939, urges that a beginning be made at the Washington Assembly to adopt new terms on the basis of Latin and Greek roots, these terms to have strict meanings for all countries. The following are tentative suggestions for such a beginning, based especially on information from France, Germany, Great Britain, Holland, Japan, Russia, and the United States.

Almost every extensive practical investigation of ground‐water supplies offers some opportunity for study of fundamental problems, in fact many of them require such fundamental study. With a larger number of investigations in progress, and with fairly liberal appropriations much new and valuable information is being discovered. Some idea of the increase in ground‐water studies since the organization of the Section of Hydrology may be given by a few statistics on the work of the Division of Ground‐Water of the Federal Geological Survey, which does the largest amount of ground‐water work in the United States. In 1932 the Division worked on about 50 projects in 25 States, in 15 of which and in Hawaii the investigations were made in cooperation with States, or other local Governmental agencies. During the current fiscal year work has been completed, or is in progress, on about 100 investigations in 35 States, Hawaii, and the Virgin Islands. The number of States cooperating on the work has increased to 24. During the current fiscal year about \\$375,000 will be spent for ground‐water investigations by the Federal Geological Survey and cooperating organizations, as compared to about $175,000 spent during the fiscal year ended June 30, 1932.

In 1938, as in previous years, the Committee devoted its energies primarily to the collecting of data on the variations in length and volume of American glaciers, it being felt that the maintenance of a continuous record of these variations is of prime importance, not only to hydrology and glaciology, but, as has become increasingly evident recently, also to climatology, geomorphology, geography, ecology, history, and archaeology. As the time available for the work of the Committee is limited and does not permit covering the entire field of glaciology, it seems best to devote it before all else to this line of research which yields results of value to so many different sciences. Besides, the gathering of data on glacier‐oscillations is not a one‐man job that can be taken up or dropped at convenience from time to time, but is an organized and far‐flung enterprise whose success depends upon the faithful cooperation of many volunteer workers located in different parts of the country. Such an enterprise, once launched, must be kept running or it will disintegrate and the precious enthusiasm of the field‐workers will be lost.

Geological and hydrological studies comprised the principal part of the investigation, and these studies were supplemented by measurements of earth‐resistivity made largely by the Geophysical Section of the Geological Survey along traverses aggregating 51 miles. The extent to which resistivity‐methods may be useful in ground‐water work has been the subject of much discussion. A full evaluation of the method can not be made at this time. However, the work in the El Paso Area indicates that the presence of faults and of underground bodies of salt water may be definitely determined by resistivity‐measurements.

In the broad sense, based on the etymology of the term, geophysics means the physics of the Earth. This is its significance in the names “Geophysical Laboratory of the Carnegie Institution of Washington,” “International Union of Geodesy and Geophysics,” and “American Geophysical Union.” In this sense the sciences of geology and hydrology are largely geophysics, although in part they are geochemistry or biology. Geologists and hydraulic engineers who are elected to membership in the American Geophysical Union are, however, often surprised to find that they are regarded as “geophysicists.” I hope that when the Union establisnes a journal, its name will include the expression “Earth physics” or “Physics of the Earth,” in order that there will be no misunderstanding as to its scope.

This action by the officers provides for greater participation of the members of the Section in committees, and is a step well worth while. The personnel of the Committee as of May 1, 1937, is as follows:
H. K. Barrows R. W. Davenport I. E. Houk F. T. Mavis F. F. Snyder
M. M. Bernard R. S. Goodridge W. G. Hoyt A. F. Meyer H. C. Troxell

I consider it an honor to act as Chairman of the Committee on Runoff but regret, however, that I have been unable as yet to coordinate thoroughly the work of the Committee or to inform myself adequately on many runoff‐experiments and research‐problems. Consequently, my report will be very brief and informal.

However, geophysics is coming to have a place in hydrologic investigations, and these results may throw some light on what can be accomplished by resistivity‐measurements.
We have found that,for many questions not involving exact determinations of depth, resistivity‐ measurements give conclusive answers. Ordinarily a reliable answer can be expected to the question of the existence of a buried channel if the covering is composed of unconsolidated material with a resistivity differing from that of the rock. For example, topographic surveys were made at two alternative dam‐sites on a river about four miles apart. Examination of the surface‐geology indicated that a channel burled under glacial debris possibly existed at each site, but resistivity‐measurements proved that such a channel existed at one site and not at the other. On the other hand, at another site the geologist suspected there might be an old channel on a steep side hill. Geophysical measurements showed a depth of overburden of 46 feet and showed that if a deeper channel exists it must be narrow; but they did not show positively that no such channel exists. Probably a careful survey with a large number of lines would have given a more definite answer, but the rough topography interfered with the resistivity‐work, and time and money were not available for a detailed survey. After completion of the geophysical work, the geologist located some outcrops which led him to conclude that no old channel exists at this site. At two other dam‐sites in Oregon resistivity‐measurements showed that there were no burled channels.

Kleberg County, Texas","docAbstract":"Abundant supplies of fresh water are obtained from deep artesian wells In all parts of Kleberg County. The water is derived from a stratum of sand, 10 to 150 feet thick, which usually has been referred to the Goliad sand but possibly may be at the base of the LIssie formation. The top of the sand Is reached at depths of around 400 feet In the western part of the county, 600 to 700 feet In the locality of Klngsville, and 1,250 to 1,450 feet In the eastern part of the county. Small supplies of fairly good water are obtained from shallow wells In very sandy areas in the eastern and southern parts of the county, but with this exception, so far as known, no good water has been obtained In the county either above or below the artesian fresh-water horizon.
\nThe fresh artesian water Is supplied by percolation from the outcrop of the water-bearing sands, which is many miles to the west In Jim Wells, Brooks, and Duval Counties. The estimated average replenishment from the outcrop to the wells of Kleberg County is 3,000,000 gallons a day.
\nAvailable Information regarding most of the wells of the county Is given in the table of well records. Of the 43V wells listed 34 are not In use, and the water supplies from the others are used as follows: , Entirely for stock, 151; domestic use and stock, 241; public supply, 3; Industrial supply, 2; Irrigation, 4; railroad supply, 1; unrecorded, 1. About 80 are flowing wells In the southern and eastern parts of the county.
\nIt is concluded that the total withdrawal from those wells averages about 4,000,000 gallons a day. Some water is wasted, but the amount is not very great.
\nThere has been a general decline In the artesian head throughout the county. The largest decline has been in the western part of the county and In the vicinity of Klngsville, where the water level is now 15 to 45 feet below the surface in wells that once had a strong flow. Wells continue to flow in the southern and eastern parts of the county, but under less head than formerly. There was a small net loss in head in most parts of the county between the winters of 1932-33 and 1934-35, indicating that the decline is slowly continuing. Originally the artesian pressure In the fresh-water sands was much higher than the pressure In the overlying saltwater sands, but this relation has been reversed in the western part of the county and In the district around Klngsville, as a result of the decline in artesian head.
\nWater obtained from the fresh-water horizon is comparatively fresh in the western and central parts of the county but contains a somewhat higher proportion of chlorides toward the Gulf. Samples obtained from about 100 wells, located for the most part in the central part of the county, showed a. higher chloride content than is normal for the freshwater beds in the area. These wells are believed in large part to be defective and to be admitting salt water. This was demonstrated and the leaks located in several wells that were tested. No evidence was found of salt-water contamination by percolation through the formations, however. The leaky wells should be repaired, If practicable, or sealed to prevent them from contaminating the fresh-water sand. The chances of leaks developing can be largely eliminated If the wells are properly drilled and provided with casing of good grade, and the casing is adequately seated.

It has, however, seemed that this year a worth‐while group of papers could be developed on the broader subject of fluctuations of ground‐water levels.

As proof of this statement it is only necessary to state that of 57 papers listed for presentation at the present annual meeting of the Section of Hydrology and of the Pacific Coast meeting of the Section on January 31 and February 1, 26 papers, or 45 per cent, related to some phase of ground‐water hydrology. In this connection, attention may be called especially to the papers on ground‐water presented at the Pacific Coast meeting and published in the present Transactions.
At this early point in his report, the Chairman should state that at about the time he usually takes the preliminary steps in compiling data for his annual report, his official duties somewhat unexpectedly took him to field‐work in New Mexico and Colorado. Without the usual office facilities it has not been possible for him to make all desired contacts, and the present report of current ground‐water studies is necessarily somewhat incomplete.

An investigation was therefore undertaken by the writer, under the direction of 0. E. Meinzer, in the Hydrologic Laboratory of the United States Geological Survey, to determine whether Darcy's law is valid for very low hydraulic gradients—that is, whether under such low gradients the rate of flow remains proportional to the gradient. In a previous paper by Meinzer and the writer (Amer. Geophysical Union,15th annual meeting, pp.405–409, 1934), it was shown that for the sand tested the rate of flow varies directly with the hydraulic gradient down to a gradient of about one foot to the mile. More recently six additional tests have been made on this sand with the same apparatus, and these tests give evidence of the validity of Darcy's law for still lower gradients.

The problems relating to the development of ground‐water supplies are both quantitative and qualitative. They include such problems as the decline in yield of wells in areas of large withdrawals of water and salt‐water contamination of ground‐water supplies. In order to facilitate a better understanding and interpretation of hydrologic conditions relating to these local ground‐water problems, a general survey of the artesian water in the Florida Peninsula was made by the United States Geological Survey in 1934.

There have, accordingly, been some changes in the membership of the Committee on Underground‐Water. Certain members have retired because of pressure of other duties or because they are no longer actively engaged in ground‐water work. Dr. O. E. Meinzer, who retired as Chairman of the Section of Hydrology, has agreed to serve on the Committee, and probably two or three other men will be appointed to make contact with special phases of the field covered by the Committee. It is with regret that the Chairman reports the loss to the Committee by the death of A. F. Melcher, who had contributed much to the science of ground‐water hydrology by his studies on permeability and absorption of sedimentary formations for water, oil, and gas. ©1934

D. Wyckoff and others [42] a unit of permeability is proposed which is based on centimeters, seconds, and atmospheres of pressure (76 centimeters of mercury).
In 1923, when the Hydrologic Laboratory of the United States Geological Survey was organized, much study was given to the question of a coefficient of permeability, and a coefficient was adopted which is based on feet and gallons a day (U.S. Geol. Survey Water-Supply Paper 596, p. 148). This coefficient has been extensively used and has proved very satisfactory in ground-water work. It has the merit of being readily applicable to field-conditions. It is, moreover, of convenient size, the coefficients of most water-bearing materials being integers of two or three figures, that is, between 10 and 1000. It was adopted in place of Slichter's “transmission-constant” (U.S. Geol. Survey Water-Supply Paper 67, p. 27, 1902), after much careful consideration, largely because the “transmission-constant” of most water-bearing materials is inconvenient in being only a small decimal.
