Project development and data programs for assessing the quality of the Willamette River, Oregon
David A. Rickert, Walter G. Hines, Stuart W. McKenzie
1976, Circular 715-C
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Effects of off-road vehicle use on the hydrology and landscape of arid environments in central and southern California
Charles T. Snyder, D. G. Frickel, R. F. Hadley, R.F. Miller
1976, Water-Resources Investigations Report 76-99
Two widely separated sites in California used for motorcycle hill-climbing were studied to evaluate the impact on the landscape and hydrology. At Panoche Hills in central California, an area formerly used by motorcycles together with an adjacent unused area were monitored from 1971 to 1975. Observations in both areas included...

Chemical quality of ground water in the Tehama-Colusa Canal service area, Sacramento Valley, California
Gilbert L. Bertoldi
1976, Water-Resources Investigations Report 76-92
The Tehama-Colusa Canal Service Area consists of about 450 square miles of irrigable land located on the west side of the Sacramento Valley, Calif. Upon the completion of the Tehama-Colusa Canal, it is expected that most of the service area will switch from passive forms of agriculture (dry farming and...

Mathematical model of the West Bolsa Ground-water Basin, San Benito County, California
Robert E. Faye
1976, Water-Resources Investigations Report 76-71
Simulation of the West Bolsa ground-water basin hydrology in California had provided values of basin recharge and discharge and nodally distributed values of transmissivity and storage coefficient. Average net recharge from April 1945 to March 1969 was 6.2 cubic feet per second and occurred as subsurace recharge and infiltration of...

Preliminary report on water availability in the lower Ship Creek basin, Anchorage, Alaska : with special reference to the fish hatchery on Fort Richardson and a proposed fish-hatchery site near the Elmendorf Air Force base power-plant
Geoffrey W. Freethey
1976, Water-Resources Investigations Report 75-48
The availability of surface water and shallow ground water in the lower Ship Creek basin, Anchorage, Alaska, was examined using 28 years of streamflow records and well logs. Streamflow gains and losses were estimated from 23 seepage investigations made since May 1957. A contour map of the top of the...

Methodology for river-quality assessment with application to the Willamette River basin, Oregon
David A. Rickert, Walter G. Hines, Stuart W. McKenzie
1976, Circular 715-M
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Availability of water in the Floridan aquifer in southern Duval and northern Clay and St. Johns counties, Florida
R.W. Fairchild
1976, Water-Resources Investigations Report 76-98
The Floridan aquifer within the area of investigation consists of 1,100 to 1,800 feet of soft, porous limestone interbedded with hard, dense limestone and dolomite overlain by several hundred feet of confining beds. From late 1948 to May 1972, water levels in wells tapping the Floridan aquifer declined as much...
Estimating runoff volumes and flood hydrographs in the Colorado River Basin, southern Utah
James H. Eychaner
1976, Water-Resources Investigations Report 76-102
Hydrographs of 364 floods from 18 continuous-record gaging sites in the Colorado River basin in southern Utah were used to define a single relation of flood volume to peak discharge; the standard error of estimate of that relation . is 82 percent. Using the same data, a mean dimensionless hydrograph...

Phosphatic pebbles are widespread in basal units of the Marquette Range Supergroup (Precambrian X) in the central part of the Upper Peninsula of Michigan. At one locality, a conglomeratic bed about 15 m thick averages about 15 percent P2O5, and many thinner beds are of comparable grade. This occurrence is...
