Base of fresh ground water approximately 3,000 micromhos in the Sacramento Valley and Sacramento-San Joaquin Delta, California
Charles F. Berkstresser Jr.
1973, Water-Resources Investigations Report 73-40
The study area consists of about 6,600 square miles; about 5,500 square miles of the floor of the Sacramento Valley, and about 1,100 square miles of the Sacramento-San Joaquin Delta.  The Sacramento Valley, as defined by Bryan (1923, p. 8), extends from Red Bluff 145 miles southward to Suisun Bay. ...
Artificial-recharge experiments and operations on the Southern High Plains of Texas and New Mexico
Richmond F. Brown, Donald C. Signor
1973, Water-Resources Investigations Report 73-10
Experiments using highly turbid water from playa lakes for injection into the Ogallala Formation have resulted in greatly decreased yield of the recharge wells, Recharge of ground or surface water of good quality has indicated, however, that injection through wells is an effective method of recharging the aquifer. Water that...
Index of time-of-travel studies of the US Geological Survey
Charles W. Boning
1973, Water-Resources Investigations Report 73-34
This index identifies locations on streams where the U. S. Geological Survey has investigated the time of travel of a highly soluble material moving through a reach of stream channel. This index provides information only on the location of studied stream reaches; it contains no basic data. It does contain,...
A survey of the water resources of St. Thomas, Virgin Islands
D.G. Jordon, O. J. Cosner
1973, Open-File Report 72-201
St. Thomas, with an area of 32 square miles, is the second largest of the Virgin Islands of the United States. The island is mountainous, and slopes commonly exceed 35 degrees along a central ridge 800 to 1,200 feet high running the length of the island. The general appearance is...
Predicted effects of proposed navigation improvements on residence time and dissolved oxygen of the salt wedge in the Duwamish River estuary, King County, Washington
W.L. Haushild, J.D. Stoner
1973, Open-File Report 73-102
A model of the circulation and quality of water in the Duwamish River estuary has been sufficiently developed to allow prediction of the effects of a proposed widening and deepening of waterways on residence time and dissolved oxygen in the estuary's salt wedge. For a low river-discharge period in August...
Preliminary investigation of land subsidence in the Sacramento Valley, California
B. E. Lofgren, R. L. Ireland
1973, Open-File Report 74-1064
Although a number of agencies have made leveling surveys in Sacramento Valley and a valleywide network of first- and second-order control exists, few areas have sufficient control for determining whether land subsidence has occurred and if so, how much, within the time span of vertical control. Available data suggest that...
Water-budget studies of lower Mesilla Valley and El Paso Valley, El Paso County, Texas
W.R. Meyer, J.D. Gordon
1973, Open-File Report 73-185
The total inflow of water to the lower Mesilla Valley in 1970 was 390,510 acre-feet. Of this amount, 43,300 acre-feet was consumptively used by crops and phreatophytes and 4,700 acre-feet was lost by evaporation. Ground-water storage increased by 320 acre-feet, and 360,860 acrefeet left the valley as surface- and ground-water...
Measurement of lateral erosion at proposed river crossing sites of the Alaskan pipeline
James Brice
1973, Open-File Report 73-31
This study of lateral erosion rates by comparison of aerial photographs was undertaken at the request of D. M. Culbertson, hydraulic engineer, U.S. Geological Survey, Menlo Park, Calif., and preparatory work in Alaska (during June 1-18, 1971) was done with the cooperation of Harry Hulsing, district chief, Alaska District. Examination...
Preliminary report on the geology along the Atlantic Continental margin of the northeastern United States
James P. Minard, W. J. Perry Jr., Elaine G. A. Weed, E. C. Rhodehamel, E. I. Robbins, R. B. Mixon
1973, Open-File Report 73-191
The U.S. Geological Survey is conducting a geological and geophysical study of the northeastern United States Outer Continental Shelf and the adjacent slope from Georges Bank to Cape Hatteras. The study also includes the adjacent Coastal Plain because it is a more accessible extension of the shelf. The total study...
