Book Description

This report is one of nine reference sources to be used for the preparation of an Environmental Impact Statement (EIS) by the U.S. Army Engineer District, St. Louis. Twenty-three side channels were sampled in June and August 1972 and 13 of the 23 side channels and 4 river border areas were sampled in July 1973. Physicochemical parameters sampled were dissolved oxygen, temperature, turbidity, pH, and alkalinity. Biological elements sampled were plankton, benthos, and fish. Meteorological parameters included wind velocity, cloud cover, and ambient air temperature. Other physical parameters measured were bottom sediments and discharges. Methods and materials used to gather data are described. This report includes the physical, biological, and chemical raw data, a consolidation of data for each sampling area, and a brief summation of the results for each area. No attempt was made to correlate data among sampling areas. Another WES report will include an overall assessment of the aquatic data. (Modified author abstract).
