1991, Water-Resources Investigations Report 91-4127
Ponded depth in an artificial-recharge basin was used as a management option to conduct turbid water from the James River to the Oakes aquifer. Infiltration-rate response to changes in ponded depth was evaluated for a 15xl5-meter artificial-recharge test basin constructed in a medium-sandy soil in the irrigation area near Oakes,...

The Regional Aquifer-System Analysis (RASA) Program of the U.S. Geological Survey was initiated in 1978. The purpose of this program is to define the regional geohydrology and establish a framework of background information on geology, hydrology, and geochemistry of the Nation's important aquifer systems. This information is critically needed to...

Lakes Clara and Vandercook are 33- and 43-hectare lakes, respectively, located in predominantly sandy outwash in north-central Wisconsin. Annual precipitation at National Weather Service stations during the 1951-80 calendar years averaged 794 millimeters near Lake Clara and 834 millimeters near Vandercook Lake. During the 1981 water year, annual precipitation measured...
