The seasonal and spatial distributions of the American woodcock (Philohela minor) in Oklahoma were determined through field surveys and the collection of all known reports of woodcock sightings. Woodcock were reported in Oklahoma in all seasons and were most Jrequently sighted from 11 October to 10 January. The peak in fall migration occurred between 11 November and 10 December. Woodcock were fo

There is some evidence of the impact of direct mortality from oil spills on bird populations, but very little is known about the sublethal and indirect effects of oil on birds. Research at the Patuxent Wildlife Research Center, Laurel, Maryland, is directed at (1) determining the effects of petroleum on the physiology and reproductive success of birds, and (2) developing the analytical methodolog

Results of water-loss studies for Jordan Creek near Allentown, Pa. are presented in both tabular and graphical form. The reach studied is approximately 24 miles long and extends from a point near Lowhill, Pa. to a point in Allentown, Pa. The drainage area at Allentown is about 76 square miles. In portions of the study area, Jordan Creek loses considerable parts of its flow to the permeable limesto

A hydraulic analysis of the lad River in a reach at Springfield, Ohio was made to determine the effects of relocating State Highway 41 in 1S76. The main channel was cleaned by dredging in the vicinity cf the new highway bridge and at the Detroit, Toledo and Ironton Railway bridge upstream. The new highway was placed on a high fill with relief structures for flood plain drainage consisting of a 12-

Chemical quality of surface water within the Feather Creek watershed is generally good. However, fecal bacteria concentrations are high enough to represent a potential problem, especially because of the high water-contact recreation proposed for the future reservoir. Chemical analyses of surface-water samples collected on October 9, 1974, and periodically from October 1, 1975, to September 28, 197

Past land-use practices, including mining, in Allegheny County, Pa., have resulted in three principal environmental problems, exclusive of air and water contamination. They are flooding, landsliding, and subsidence over underground mines. In 1973, information was most complete relative to flooding and least complete relative to landsliding. Accordingly, in July 1973, the U.S. Geological Survey (US

Published data show that estimated water consumption varies with the cooling system adopted, being least in once-through cooling (about 18 cubic feet per second per 1,000 megawatts electrical) and greatest in closed cooling with mechanical draft towers (about 30 cubic feet per second per 1,000 megawatts electrical). When freshwater is used at this magnitude, water-resources economy may be affected

Estimates of water use in the United States in 1975 indicate that an average of about 420 bgd (billion gallons per day) about 1,900 gallons per capita per day was withdrawn for the four principal off-channel uses which are (1) publicsupply (for domestic, commercial, and industrial uses), (2) rural (domestic and livestock), (3) irrigation, and (4) self-supplied industrial (including thermoelectric

Robbins Nest is located on the fall line one-half mile below Rocky Gorge Reservoir. During the fall migration, about 8 nets are run on the upper part of the 3 acres (edge of the lawn, the garden, under the Virginia Pines, and the upper edge of the mature oak woods that drop 80 feet to the Patuxent River). Foul weather on weekends, combined with commitments away from home, severely restricted this
