A summary is reported of two surveys conducted to determine the effects of six power plants on temperature, periphyton and macroinvertebrates in the White River at Petersburg, Indiana and in the Wabash River. Measurements of all parameters were taken before and after operation of the power plants to establish changes in water temperature and the relation of any changes to the distribution and composition of the other parameters. Only one station on the Wabash River experienced marked changes: a temperature increase of 5F above the ambient limit on several occasions and an increase of periphyton and macroinvertebrate samples in the area of the discharge canal. The White River plants experienced a 5F rise more frequently than did the Wabash River plant, and macroinvertebrate and periphyton populations increased most significantly at a point 100 yards downstream from both plants. The temperature range which most affected the macroinvertebrates was 95-99F.
