Chemical analyses of surface water in Illinois, 1958–74—Volume II, Illinois River basin and Mississippi River tributaries north of Illinois River basin Chemical analyses of surface water in Illinois, 1958–74—Volume II, Illinois River basin and Mississippi River tributaries north of Illinois River basin
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 included for all sites where samples were collected at gaging...

Geohydrology of Muscatine Island, Muscatine County, Iowa Geohydrology of Muscatine Island, Muscatine County, Iowa
Muscatine Island is a wide segment of the west bank of the Mississippi River flood plain that covers about 50 square miles in Muscatine and Louisa Counties; the project area encompasses the 30 square miles in Muscatine County. The flood plain is underlain by thick, permeable alluvial deposits that comprise a water-table aquifer that is developed extensively for water supplies in the area...

Technique for estimating magnitude and frequency of floods in Illinois Technique for estimating magnitude and frequency of floods in Illinois
A technique is presented for estimating flood magnitudes at recurrence intervals ranging from 2 to 500 years, for unregulated rural streams in Illinois, with drainage areas ranging from 0.02 to 10,000 square miles. Multiple regression analyses, using streamflow data from 241 sampling sites, were used to define the flood-frequency relationships. The independent variables drainage area...

Floods in the Big Creek basin, Linn County, Iowa Floods in the Big Creek basin, Linn County, Iowa
Flood information for the Big Creek basin in Linn County, Iowa, should be of use to those concerned with the design of bridges and other structures on the flood plains of the streams. Water-surface profiles for the flood of May 1974 are given for Big Creek and its major tributaries, East Big, Crabapple, Elbow, and Abbe Creeks. The May 1974 flood was at least a 50-year flood on East Big...

Water quality characteristics of six small lakes in Missouri: Mo. Dept. of Natural Resources. 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 stratification lasts about one month longer in the...

Flood of June 27, 1975, in City of Ames, Iowa Flood of June 27, 1975, in City of Ames, Iowa
On June 27, 1975, the city of Ames and vicinity sustained severe flooding from Squaw creek and the south Skunk River. The storm which preceded the flood was net particularly outstanding in its intensity or duration. However, antecedent conditions plus the timing and direction of the storm were "ideally tuned" to cause the flood. In terms of magnitude of discharge as well as of damages...
