Dear Mr. Mosely Matthew Stillwell, Jeff DeBerardinis, and Debra Owen of my staff have reviewed the 2014 Environmental Monitoring report for fish community structure, fish tissue, and physical -chemical data respectively. This report was received by the Water Sciences Section (WSS) on January 12ii', 2015 In terms of fish tissue data, trends indicate very little change in metal concentrations in Hyco Lake fish tissues and these levels have remained well below the North Carolina Department of Human Health Service's (NCDHHS) action levels for Se and Hg and for screening values for As, Cd, and Cu. In addition, there have been no significant changes in the physical -chemical water chemistry values over time. Based on a review of the 2014 data provided, the historic fish biomass, abundance, relative weight, and quality of the fishery present in Hyco Reservoir is comparable to the levels associated with these parameters as reported by Duke -Progress biologists over the last several years In addition, there are no significant differences in the fishery uplake to downlake. As a result, based on the current and historical data provided, the 2014 fishery data meet the definition of a Balanced and Indigenous Population However, for inclusion in future reports please add historic fish community structure data Historic data is already included for water chemistry parameters and for fish tissue data but is not included for the fish community. Including this data in subsequent reports will expedite our review. Specifically, please include historic data for the following fish community parameters fish biomass, abundance, and relative weight. The fishery data should include the same historic reporting years as water chemistry parameters and fish tissue If you have any questions, please do not hesitate to contact me or my staff Sincerel t Die M Reid Chief, Water Sciences Section Cc, Danny Smith, Raleigh Regional Office Tom Belnick, Surface Water Protection Section Ken Rudo, NCDHHS Water Sciences Section 1621 Mail Service Center, Raleigh, North Carolina 27699-1621 Location 4401 Reedy Creek Road, Raleigh, North Carolina 27607 Phone 919-743-8400 \ FAX: 919-743-8517 Intemet http:llportal.ncdenr.orgtweb/wgless/home An Equal Opportunity\Affirmative Action Employer
