apparently exerts an oxygen demand, keeps aquatic plants from growing, 

 and does not support an abundance of food organisms . 



More and better waste treatment facilities are being constructed 

 by industries and municipalities in the drainage basin of the Illinois 

 River. However, the production of fish and wildlife in the Illinois 

 River and its bottomland lakes is not likely to improve unless sediment 

 pollution is also brought under control. 



The consequences of future uses of land in the drainage basin and 

 the consequences of future uses of the river must be predicted, so that 

 a wise selection of alternatives can be made. If the river is to be 

 managed in the future for a variety of beneficial uses, then the various 

 State, Federal, and private agencies charged with managing land and 

 water within the drainage basin must work in a coordinated fashion, 

 rather than at cross purposes.
