Water quality characteristics of six small lakes in Missouri: Mo. Dept. of Natural Resources.

A study of six small lakes, representative of those in the major physiographic regions of Missouri, shows variation in physical. chemical, and biological characteristics related to their location in the Slate. For example, because of climatic differences, ice cover and winter stratification are more prevalent in northern Missouri. Summer...

Bedrock topography of northeast Iowa

The bedrock in Iowa (Hershey, 1969) is generally overlain by deposits of glacial drift and alluvium, which range in thickness from less than 1 foot (0.3 m) to more than 400 ft (18 m), respectively. The configuration of the bedrock surface is the result of a complex system of ancient drainage courses when were developed during a long period of...

Drainage areas for Illinois streams

Drainage areas were tabulated for all streams in Illinois which drain over 100 square miles. at sites where streamflow data have been collected, and at other selected locations. Areas were planimetered on U.S. Geological Survey topographic quadrangle maps and balanced to known areas taken from Smithsonian Geographical Tables of...

Quality of water in the Red River alluvial aquifer, Shreveport, to the mouth of the Black River, Louisiana

Chemical analyses of water samples from 296 wells in the Red River alluvial aquifer indicate that the ground water in the valley is generally hard (more than 120 milligrams per liter) and has a high iron concentration (greater than 6,000 micrograms per liter). The predominant ions found in the water were calcium and bicarbonate. However, in places...
