The description should be written chronologically, with changes in the monitoring program described. At a minimum this should include: - for fish species in Lake Wylie, a description of the methods used (such as gill netting, electro-fishing, purse seine), the timing of each survey, and locations surveyed; and - similar information for surveys of benthic organisms, planktonic species, and other aquatic invertebrates is also requested. Response to Environmental RAI 1 There were no aquatic ecology surveys conducted for benthic organisms, planktonic species, and other aquatic invertebrates after the completion of the studies conducted for the 316(a) demonstration. However, aquatic ecology surveys for fish species were performed after the completion of the 316(a) studies. The detailed description of the aquatic ecology surveys conducted for fish species is provided below. Detailed Description of the Aquatic Ecology Surveys Conducted for Fish Species: Subsequent to the submittal of the Catawba Nuclear Station, Supplemental 316(a) DemonstrationData dated January 1993, fisheries monitoring studies at the Catawba Nuclear Station (CNS) discharge, Location 215, and uplake reference, Location 216, were performed during 1991 and from 1993 through 1996. Since the post-1990 monitoring was not required, these data have not been summarized in a report. Additionally, littoral (shoreline electrofishing) and limnetic (hydroacoustics and purse seine) fish community assessments were conducted on Lake Wylie during 1993 through 1997 and in 2000, as part of a watershed sampling program for the Catawba River reservoirs in North and South Carolina. A portion of the littoral fish community data collected during 1993 through 1997 are summarized in the October 2000 Duke Power Report "The Catawba". The liunetic fish community data collected during 1993 through 1997 are summarized in the Duke Power report Catawba River ForageFish Densities, PopulationEstimates, and Species Composition: 1993 -1997. The littoral and limnetic fish community data collected during 2000 have not been summarized in a report. The CatawbaNuclear Station, Supplemental 316(a) DemonstrationData report summarized the results of Lake Wylie fisheries sampling through 1990.
