Docket Nos. 50-269, -270, -237

Dear Mr. Rusche:

un January 20, 1976, four of the 24 condenser cooling water (CCW) intake screens at the Oconee Nuclear Scation were inspected.

A total of 43,237 small fingerling fish, weighing 109.7 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 109.7 Kg. of fish had an insignificant effect on fisheries resources in Lake Keowee.

Very truly yours, h.
