Dear Mr. Rusche:
On January 8 and 9, 1976, eight of the 24 condenser cooling water (CCW) intake screens at the Oconee Nuclear Station were inspected. A total of 5,343 small fingerling fish, weighing 13.5 Kg., had collected on the screens. The fish were removed from the screens and categorized, where possible, as to screen location, type, size, degree of decomposition, and weight. This information is tabulated in Enclosure 1.
It is concluded that the mortality of these 13.6 Kg. of fish had an insignificant effect on fisheries resources in Lake Keowee.
