Limnology of Oneida Lake with emphasis on factors contributing to algal blooms
Phillip E. Greeson
1971, Open-File Report 72-139
Oneida Lake is a naturally eutrophic lake that has existed for about 10,500 years. It has been in a eutrophic state for at least 350 years, and the geochemically derived dissolved materials entering the lake from the drainage basin are of sufficient quantity (449,700 tones per year) to support annual...
Geology, hydrology, and water quality of the Tracy-Dos Palos area, San Joaquin Valley, California
W. R. Hotchkiss, G. O. Balding
1971, Open-File Report 72-169
The Tracy-Dos Palos area includes about 1,800 square miles on the northwest side of the San Joaquin Valley. The Tulare Formation of Pliocene and Pleistocene age, terrace deposits of Pleistocene age, and alluvium and flood-basin deposits of Pleistocene and Holocene age constitute the fresh ground-water reservoir Pre-Tertiary and Tertiary sedimentary...
Hydrology and sedimentation of Corey Creek and Elk Run basins, north-central Pennsylvania
Lloyd A. Reed
1971, Water Supply Paper 1532-E
Analysis of data collected from two small agricultural basins in northcehtral Pennsylvania during the period May 1954 to September 1967 indicates that conservation measures reduced the quantity of suspended sediment leaving the Corey Creek basin as a result of frequent storms during the growing season. Extensive soil conservation treatments were...
Summary of floods in the United States during 1966
J.O. Rostvedt
1971, Water Supply Paper 1870-D
This report describes the outstanding floods in the United States during 1966. The four most destructive floods occurred during March-April in the Red River of the North basin in northwestern Minnesota, during April-May in northeastern Texas, in August, in east-central Nebraska, and in December, in the Southwestern United States. For...
Ground-water reconnaissance of selected sites in Rocky Mountain National Park and Shadow Mountain National Recreation area, Colorado
F.A. Welder
1971, Open-File Report 71-320
An evaluation of the ground-water supply potential at 30 sites within the Rocky Mountain National Park and Shadow Mountain National Recreation Area was made by the U.S. Geological Survey in 1967 and 1968. The work consisted of a geohydrologic reconnaissance, well inventory, and test drilling. The study sites are underlain...
Ground-water hydrology of the San Pitch River drainage basin, Sanpete County, Utah
Gerald B. Robinson Jr.
1971, Water Supply Paper 1896
The San Pitch River drainage basin in central Utah comprises an area of about 850 square miles; however, the investigation was concerned primarily with the Sanpete and Arapien Valleys, which comprise about 250 square miles and contain the principal ground-water reservoirs in the basin. Sanpete Valley is about 40 miles...
Sediment loads in canals 18, 23, and 24 in southeastern Florida
William A. J. Pitt Jr.
1971, Open-File Report 72-299
Suspended-sediment concentrations and suspended-sediment discharges were determined in selected canals in St. Lucie, Martin, and Palm Beach Counties, in southeastern Florida. Sediment rating curves were developed to relate water discharge to sediment concentration at the three sites sampled. An evaluation of the concentration and sediment loads shows that larger amounts...
Blackbirds and the southern rice crop
Brooke Meanley
1971, Resource Publication 100
Blackbirds have been a problem to the rice grower since colonial times. The problem has existed wherever rice is grown because man, by his culture of rice (Oryza sativa), creates food-rich ricefield marshes that apparently are more attractive to blackbirds than the natural marshes in which they have flourished for...
Channel movement of meandering Indiana streams
James F. Daniel
1971, Professional Paper 732-A
The process of channel movement in a meander system involves rotation and translation of meander loops and an increasing path length. The amount of path-length increase is directly proportional to the impulse supplied by discharge and is inversely proportional to the silt-clay percentage of the material composing the channel perimeter. Comparable...
