The three most destructive floods occurred in March from Alabama to West Virginia and Ohio, in June in Nebraska, and in August in Buffalo, N.Y.</p><p>Widespread disastrous floods struck the western slopes of the Appalachian Mountains from Alabama to West Virginia and Ohio as a result of three storms moving over the area during March 4-19. Precipitation during the first storm period, March 4-6, caused some major stream overflows and produced conditions favorable for high runoff from subsequent rainfall. Heavy rainfall on March 11-13 produced record-breaking floods on many streams in Tennessee, Kentucky, Virginia, and West Virginia. Noteworthy floods occurred in the bordering States of Alabama, Georgia, North Carolina, and Ohio. The third storm on If arch 16-19 was .significant because it prolonged the period of flooding and produced high-volume runoff in some areas. Twenty-six lives were lost, and more than 30,000 persons were forced from their homes. Damage to highways, railroads municipal and private property amounted to approximately \\$98 million.</p><p>Floods of June 24 in small basins in east-central Nebraska were the most severe known in the area. Discharges in many streams greatly exceeded the 50-year flood. Twenty-five cities and villages and more than 600 families suffered property loss. Three lives were lost. Property loss was about \\$13 million.</p><p>On July 29 the most severe rainstorm in 18 years occurred in western New York. On August 7, rains of near-record magnitude again fell over western New York, and record intensities were recorded in Buffalo for 1-, 2-, and 6-hour storms.

These sites are Columbia River at Vancouver, Wash., Willamette River at mouth, Columbia River at St. Helens, Oreg., Columbia River at Longview, Wash., and Columbia River at mouth. Two tables of estimates are compiled for each site. One table lists estimates of 'observed' flow, the flows that would be measured by a gaging station. The other table lists 'adjusted' flows, the 'observed' flows adjusted for storage changes in major reservoirs arid for diversion at Grand Coulee Dam. \r\n\r\nTwo methods are used in making these estimates. One method involves a detailed summation of flows from all gaged and ungaged areas, allowance for precipitation on and evaporation from the channel water surface, and adjustment of flow to allow for travel time from gaging stations at the Dalles, Oreg. (Columbia River main stem), and at Salem Oreg.

Instead, the entire drainage area below The Dalles is divided into three major inflow segments and the flow from each segment is obtained from a correlation with streams that are representative of the flow from that segment.

The most reasonable estimates prepared by those who measured some parameters of the flow were studied by Maurice Parde, who concluded that the mean annual discharge is 90,000 to 100,000 cms (cubic meters per second) or 3,200,000 to 3,500,000 cfs (cubic feet per second). A few published estimates of discharge at mouth of 110,000 cms (3,900,000 cfs) based on rainfall-runoff relationships developed for other humid regions of the world are available. \r\n\r\nThree measurements of discharge made at the Obidos narrows in 1963-64 by a joint Brazil-United States expedition at high, low, and medium river stage are referred to the datum used at the Obidos gage during the period of operation, 1928-46, and a relationship between stage and discharge prepared on the basis of the measurements and supplementary data and computations. Recovery of the original Obidos gage datum is verified by referring the 1963-64 concurrent river stages at Manaus, Obidos, and Taperinha to gage relation curves developed for Manaus-Obidos and Obidos-Taperinha for periods of concurrent operation, 1928-46 and 1931-46, respectively. The average discharge, based on the stage-discharge relation and record of river stage for the period 1928-46, is computed to be 5,500,000 cfs (157,000 cms) for the Obidos site. \r\n\r\nThe greatest known flood at Obidos, that of June 1953, is computed to have been a flow of 12,500,000 cfs (350,000 cms) at stage of 7.6 meters (24.9 feet) in the main channel and an indeterminate amount of overflow which, under the best assumed overflow conditions, may have amounted to about 10 percent of the main channel flow. Overflow discharge at stage equivalent to mean annual discharge is judged to be an insignificant percentage of flow down the main channel. \r\n\r\nMiscellaneous data collected during the flow measurements show that the tidal effect reaches upstream to Obidos at extremely low flows, the distribution of velocities in stream verticals is affected by large-scale turbulence, the standard procedure of basing mean velocity in vertical on the average of point velocities measured at 20 and 80 percent of the total depth is valid, and there is a low Manning roughness coefficient of 0.019 (English units). Samples of suspended sediment taken with a point sampler at various depths in selected verticals show, for the Obidos site, a variation in concentration from 300 to 340 mg/l (milligram per liter) near the streambed to 50 to 70 mg/l in the upper part of the verticals. \r\n\r\nMedian diameter of bed material at Obidos averaged about 0.20 mm (millimeter) in a range of 0.15 to 0.25 ram. Analyses of water samples collected at Obidos in July and November 1963 and August 1964 are presented. The reconnaissance measurements of 1963-64 provide a well-supported value of mean annual water discharge of Amazon River at Obidos and the mouth. Many more measurements of flow and water-quality characteristics are needed to obtain more exact values of discharge, suspended sediment, and salt load.","language":"ENGLISH","publisher":"[U.S. Geological Survey ],","doi":"10.3133/cir552","usgsCitation":"Oltman, R.E., 1968, Reconnaissance investigations of the discharge and water quality of the Amazon River: U.S. Geological Survey Circular 552, iii, 16 p. :illus., maps. ;26 cm., https://doi.org/10.3133/cir552.","productDescription":"iii, 16 p. :illus., maps. ;26 cm.","costCenters":[],"links":[{"id":124488,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1968/0552/report-thumb.jpg"},{"id":30626,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1968/0552/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6ce4b07f02db63e7fd","contributors":{"authors":[{"text":"Oltman, Roy Edwin","contributorId":101635,"corporation":false,"usgs":true,"family":"Oltman","given":"Roy","email":"","middleInitial":"Edwin","affiliations":[],"preferred":false,"id":147224,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The deposits in this channel were the site of some of the most productive hydraulic gold mines in California between the 1850's and 1884. \r\n\r\nThe gravel occupies a major channel and parts of several tributaries that in Tertiary time cut into a surface of Paleozoic and Mesozoic igneous and metamorphic rocks. The gravel is partly covered by the remains of an extensive sheet of volcanic rocks, but it crops out along the broad crest of the ridge between the canyons of the South and Middle Yuba Rivers. The lower parts of the gravel deposits generally carry the highest values of placer gold. Traditionally, the richest deposits of all are found in the so-called blue gravel, which, when present, lies just above the bedrock and consists of a very coarse, poorly sorted mixture of cobbles, pebbles, sand, and clay. It is unoxidized, and, at least locally, contains appreciable quantities of secondary sulfide minerals, chiefly pyrite. \r\n\r\nInformation in drill logs from private sources indicates that a 2-mile stretch of the channel near North Columbia contains over half a million ounces of gold dispersed through about 22 million cubic yards of gravel at a grade .averaging about 81 cents per cubic yard. The deposit is buried at depths ranging from 100 to 400 feet. \r\n\r\nSeveral geophysical methods have been tested for their feasibility in determining the configuration of the buried bedrock surface, in delineating channel gravel buried under volcanic rocks, and in identifying concentrations of heavy minerals within the gravel. Although the data have not yet been completely processed, preliminary conclusions indicate that some methods may be quite useful. A combination of seismic-refraction and gravity methods was used to determine the depth and configuration of the bottom of the channel to an accuracy within 10 percent as checked by the drill holes. Seismic-refraction methods have identified depressions which are in the bedrock surface, below volcanic rocks, and which may be occupied by gravels. Seismic methods, however, cannot actually recognize the presence of low-velocity gravels beneath the higher velocity volcanic rocks. Electromagnetic methods, supplemented in part by induced-polarization methods, show promise of being able to recognize and trace blue gravel buried less than 200 feet deep. A broad vague magnetic anomaly across the channel suggests that more precise magnetic studies might delineate concentrations of magnetic material. The usefulness of resistivity methods appears from this study to be quite restricted because of irregular topography and the variable conductivity of layers within the gravel.","language":"ENGLISH","doi":"10.3133/cir566","usgsCitation":"Peterson, D.W., Yeend, W., Oliver, H.W., and Mattick, R., 1968, Tertiary gold-bearing channel gravel in northern Nevada County, California: U.S. Geological Survey Circular 566, iii, 22 p. :ill., maps. ;27 cm., https://doi.org/10.3133/cir566.","productDescription":"iii, 22 p. :ill., maps. ;27 cm.","costCenters":[],"links":[{"id":124415,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1968/0566/report-thumb.jpg"},{"id":31523,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1968/0566/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad9e4b07f02db684fd5","contributors":{"authors":[{"text":"Peterson, D.

This represents an increase of 15 percent over the withdrawal of 270 bgd reported for 1960. Fresh water withdrawals for thermoelectric power generation increased nearly 25 percent during the 5 years, and saline water withdrawals increased 33 percent. An additional 2,300 bgd was used for hydroelectric power generation (waterpower), which also represented a 15-percent increase in 5 years. The quantity of water consumed-that is, water made unavailable for further possible withdrawal because of evaporation, incorporation in manufactured products, and other causes - was estimated to average 78 bgd for 1965, an increase of about 28 percent since 1960.</p><p>Estimates made of the quantities of water withdrawn from surface and ground-water sources indicate withdrawals of 61 bgd of ground water, of which nearly 0.5 bgd was saline, and 250 bgd of surface water, of which 44 bgd was saline. The estimated amount of saline water used by industry increased 36 percent from 1960 to 1965. In addition to surface and ground water sources, reclaimed sewage supplied two-thirds of a billion gallons per day, mainly to irrigation and industry.</p><p>The average annual streamflow in the United States is approximately 1,200 bgd, about four times the amount withdrawn for all purposes (except hydroelectric power) in 1965, and more than 15 times the estimated quantity of water consumed. However, comparisons of supply and demand in many river basins show that repeated use of the water is made, and at times in some basins all the available supply is consumed.</p><p>In addition to tabulations of water-use data by States and by the water-use regions previously used, water-use tables are also given for the regions recently defined by the Water Resources Council for its national assessment.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Washington, D.C.","doi":"10.3133/cir556","usgsCitation":"Murray, C.R., 1968, Estimated use of water in the United States, 1965: U.S. Geological Survey Circular 556, vi, 53 p., https://doi.org/10.3133/cir556.","productDescription":"vi, 53 p.","numberOfPages":"62","costCenters":[{"id":478,"text":"North Dakota Water Science Center","active":true,"usgs":true},{"id":610,"text":"Utah Water Science Center","active":true,"usgs":true},{"id":34685,"text":"Dakota Water Science Center","active":true,"usgs":true}],"links":[{"id":30648,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1968/0556/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":124363,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1968/0556/report-thumb.jpg"}],"country":"United States","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e5e4b07f02db5e70a0","contributors":{"authors":[{"text":"Murray, Charles Richard","contributorId":34115,"corporation":false,"usgs":true,"family":"Murray","given":"Charles","email":"","middleInitial":"Richard","affiliations":[{"id":36966,"text":"Pennsylvania Fish and Boat Commission","active":true,"usgs":false}],"preferred":false,"id":147256,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Four anomalous tracts, which range in extent from 10 to 30 square kilometers, have gold values above 10 ppb, and the richest sample contains 300 ppb. The anomalous areas seem to lack a close correlation with water depth, but they are related to areas underlain by soft Cenozoic strata that contain small quantities of dispersed gold originally derived from lodes in the Klarnath Mountains. This relationship suggests that the offshore gold accumulations are lag concentrates produced from the Cenozoic deposits by wave erosion during the postglacial rise in sea level. Gold contents at the surface are too low for economic recovery, and drilling will be required to determine whether the anomalous areas are underlain by higher grade material.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/cir605","usgsCitation":"Moore, G.W., and Silver, E.A., 1968, Gold distribution on the sea floor off the Klamath Mountains, California: U.S. Geological Survey Circular 605, iii, 9 p. :maps. ;27 cm., https://doi.org/10.3133/cir605.","productDescription":"iii, 9 p. :maps. ;27 cm.","costCenters":[],"links":[{"id":30672,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1968/0605/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":122611,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1968/0605/report-thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abde4b07f02db6740e3","contributors":{"authors":[{"text":"Moore, George William","contributorId":89123,"corporation":false,"usgs":true,"family":"Moore","given":"George","email":"","middleInitial":"William","affiliations":[],"preferred":false,"id":147288,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Silver, Eli A.","contributorId":83505,"corporation":false,"usgs":true,"family":"Silver","given":"Eli","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":147287,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Analysis of the Bonneville Dam records also indicates that in the mid-1950's a man-caused change in water-temperature regimen occurred that resulted in higher temperatures at Bonneville Dam for 10 months of the year but no change in March and April. The changes for the other months ranged from +0.5 ? to +2.0?F.
