Stage-discharge relations were developed for the Brandon Road Dam on the Des Plaines River and the Dresden Island, Marseilles, Starved Rock, Peoria, and La Grange Dams on the Illinois River. A t Brandon Road Dam, streamflow is regulated by the operation of tainter gates and headgates. Tainter gates are operated to regulate streamflow at the Dresden Island, Marseilles, and Starved Rock...

Existing surface-water quality in the Twin Ponies watershed is significantly affected by runoff from agricultural lands that comprise most of the area. Runoff effects include the addition of phosphate, organic nitrogen, fecal bacteria, trace metals, pesticides and notably suspended sediment to streaMflow, because runoff commonly is a transport mechanism for these constituents. Low-flow...

Approximately 8.0 percent of the water used in Lee County comes from underground sources. It is estimated that the use of ground water in the county currently approaches 2.8 billion gallons per year. For comparison, this amount would provide each resident with 172 gallons of water a day during a year. Actually, few if any households use this much water, and this greater per capita use...

Hydrologic information for the north-central and western coal-mining regions of Missouri is needed to define the hydrologic system in these areas of major historic and planned coal development. This report describes the physical setting, climate, coal-mining practices, general hydrologic system, and the current (1980) hydrologie data base in these two coal-mining regions. Streamflow in...

Water-level measurements in wells were started by the USGS in Iowa in 1935. Since then a total of about 450 different wells have been measured. The present network consists of about 70 wells. The measurement of these water levels aids in evaluating the present and future water resources of the State. Many factors influence water-level fluctuations. These factors include atmospheric...

Generally, the water quality of Indian Creek-Van Buren watershed is suitable as a source of Municipal, industrial and agricultural water supply and for fish and wildlife. This suitability is based upon comparisons of the existing water quality of Indian Creek to Federal and State water quality standards and criteria developed for the protection of water sources and the fish and wildlife...
