The U.S. Geological Survey Federal-State Cooperative Water Resources Program in fiscal year 1983 continued to concentrate on investigations of highest priority to the Nation. Hydrologic data collection and interpretive studies were underway in every State, Puerto Rico, and several U.S. territories with focus on such current concerns as ground-water contamination, floods, impacts of toxic wastes, acid precipitation, and stream quality. During the year, this 50-50 matching program was carried out in working partnership with more than 800 State, regional, and local agencies. Joint funding from all sources totaled approximately $92 million. Details of the program are mutually negotiated at the working level by representatives of the Survey and representatives of the cooperating agencies. The pooling of interests results in a balanced effort that directs combined resources to hydrologic investigations having the most significance to both parties. A few of the highlights for FY 1983, and how the program is developed with other agencies are described. (USGS)
The U.S. Geological Survey Federal-State Cooperative Water Resource Program is a partnership between the Geological Survey and State and local agencies for the collection of the hydrologic information needed for the continuing determination and evaluation of the quantity, quality, and use of the Nation's water resources. The first Cooperative Program was started in 1895; the Congress gave formal recognition to the partnership in 1928 and authorized Federal funding of not more than 50 percent for cooperative programs with the Geological Survey, with total funding over $80 million. The process of project selection in the Cooperative Water Resource Program is a mutual effort in which Geological Survey represents national interests, including the needs of other Federal agencies, and the cooperator represents State and local interests. The result is a balanced program that involves careful evaluation of needs, priorities, and resources. A number of typical examples of projects within the Cooperative Program are presented.
Stage-duration curves were developed for five gaging stations in Everglades National Park, Florida. Four of the five curves show similar characteristics with an increase in the slope when the water level is below land surface. Monthly stage-duration curves, developed for one of the stations, reflect the seasonal trends of the water level. Recession curves were prepared for the same five stations. These curves represent the average water-level decline during periods of little or no rainfall. They show the decline in level at the end of 10, 20, and 60 days for any given initial stage. A family of curves was also prepared to give the recession from various initial stages for any period up to 60 days.
