This report was prepared by personnel of the Iowa district of the Water Resources Division of the U.S. Geological Survey under the supervision of S. W. Wiitala, District Chief, and Alfred Clebsch, Jr., Regional Hydrologist, Central Region. It was done in cooperation with the State of Iowa and with other agencies. This report is one of a series issued by Iowa. General direction for the...

Sugar Creek, within the twin cities of Bloomington and Normal, Illinois, has differences in water quantity and quality as a result of urban runoff and overflows from combined sewers. Water-quality data from five primary and eight secondary locations showed three basic types of responses to climatic and hydrologic stresses. Stream temperatures and concentrations of dissolved oxygen...

The Current River and its principal tributary, Jacks Fork, are the Ozark National Scenic Riverway's primary natural features. About 60 percent of the baseflow in the two streams is derived from the seven largest springs in the basin. The springs are supplied by diffuse contributions from the regional aquifer system and discrete inflows from sinkholes and losing streams, some of which are...

The grid declination and mil equivalents for, the center of a quadrangle are tabulated for the four standard quadrangle map series listed above.

Samples of surface water were collected and analyzed by the Illinois Environmental Protection Agency and its predecessor, the Stream Pollution Control Bureau of the Illinois Department of Public Health. The results for the period 1958 to 1974 are presented in tabular form and the history of sampling and analytical methods are summarized. Stream discharge data from records of the U.S...

A potentiometric-surface map of the Southwest Florida Water Management District depicts the annual high water-level period. Potentiometric levels increased 15 to 30 feet between May 1977 and September 1977 in the citrus and farming sections of southeastern Hillsborough, northern Hardee, and southwestern Polk Counties. These areas are widely affected by pumpage for irrigation and have the...

Water resources data for the 1977 water year for Georgia consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs. This report contains discharge records for 100 gaging stations; stage for 9 gaging stations; stage and contents for 16 lakes and reservoirs; water quality for 19 continuous stations and 110 periodic stations; and peak...

Fresh groundwater in the Cape Lookout National Seashore in North Carolina occurs in the unconfined aquifer, an upper confined aquifer, and a lower limestome aquifer. The unconfined aquifer beneath dunes on the barrier islands is estimated to yield as much as 30 gallons per minute of freshwater to a horizontal well, but this aquifer is subject to periodic overwash by the ocean, thus...

The U.S. Geological Survey, in cooperation with the West Central Texas Municipal Water District and the Texas Department of Water Resources, is conducting a continuing program to determine the chemical quality of surface waters in the Hubbard Creek watershed. This report provides a compilation of the records for the period October 1974 to September 1976.

Several water-related problems are associated with economic development of northeast North Carolina. The solution to these problems depends in part on adequate knowledge of the hydrology of this 8,930 square mile coastal area. Average annual precipitation on the area is about 50 inches. Of this amount, about 34 inches returns to the atmosphere by evapotranspiration, about 15 inches...
