Abstract

The Keokuk area is the last source of Iowa wastes as the Mississippi flows to the southwest, leaving Iowa and then bordering the states of Illinois and Missouri. Lock and dam 19 at Keokuk forms the downstream barrier for a pool 47 miles long which is the largest on the entire Upper Mississippi River . Between lock and dam 19 and the Des Moines River mouth exist approximately 3 miles of Iowa shoreline. The Des Moines River represents the border between Iowa and Missouri at this point. Previous studies, conducted at Keokuk in October, 1968 and February, 1969, looked primarily at the chemistry and bacteriology of the river. These findings were reported to the Iowa Water Pollution Control Commission.
