Water-resources activities of the U.S. Geological Survey in Nebraska consist principally of hydrologic data collection and local, areal, or statewide interpretive studies. These programs are funded by cooperative agreements with State and local agencies, transfer of funds from other Federal agencies, and direct Federal funds. The data and results of the investigations are published or released either by the U.S. Geological Survey or by cooperating agencies. This report describes the hydrologic data-collection programs and local or areal hydrologic investigations in Nebraska during fiscal years 1993 and 1994 and provides a list of reports released by the Nebraska District during 1985-93.
