Impingement monitoring studies; deepwater generating station; Houston Lighting & Power Co. Final Report.

To fulfill requirements of the Federal Water Pollution Control Act, the impingement of aquatic organisms on the screens of HL&P's P.H. Robinson Generating Station was monitored biweekly from April 11, 1978, through March 29, 1979. Eighty-one fish species and 23 crustacean species and one mollusk species were represented in the collection. Projections for annual impingement were similar to an earlier study at the Robinson plant, correcting for the fact that flow through the plant was increased by 35% with the adition of unit 4.
