Abstract |
The report determines the extent of pollution in the rivers of the study area. The study area extends on the Mississippi River for 107 miles between its confluences with the Rum and Chippewa Rivers, on the Minnesota River from its mouth upstream 110 miles to Mankato, Minnesota, and on the St. Croix River from its mouth 55 miles upstream to Taylors Falls, Minnesota. It also investigates the principal sources of pollution and contributions from these sources, determines the effect of pollution on the numerous water uses, and develops programs for the achievement of various water uses on rivers of the study area. |
