They were: 3.3 mg/l CBOD and 0.01 mg/l NH3 (.045 mg/l NBOD). The flow from Fryes Creek is small compared to flow from Archie Elledge and Muddy Creek, so if conditions in your model are approaching background, it probably will not have a major impact on predicted model results. Let me know if questions.

DRAINAGE AREA.--178 M12. PERIOD OF RECORD. --July 1964 to September 1979,.February 1988 to September 1991 (discontinued). GAGE.--Water-stage recorder. Datum of gage is 682.67 ft above National Geodetic Vertical Datum of 1929. REMARKS. --No estimated daily discharges. Records fair. Records on falling stages following peaks above 14 ft, may be affected by backwater and subject to error. Some regulation by Salem Lake and considerable diurnal fluctuation from sewage effluent and waste water. The City of Winston-Salem diverted an average of about 31.0 ft3/s from Salem Lake in the basin and 46.0 ft3/s from the Yadkin River for water supply. An average of about 25.0 ft3/ssewage effluent was returned to Salem Creek 3.5 mi above the station.

PART IV - EVALUATION AND RECOMMENDATIONS On Tuesday, January 25, 1994, Mr. Abner Braddy and myself conducted a site evaluation of the current and proposed Twin Creeks Subdivision. Also investigated was the location of the proposed discharge point. No apparent problems were noted during this site evaluation. However, a more substantial soils report, completed by the area Health Department or a registered soil scientist, should be completed to determine the feasibility of subsurface disposal. The information submitted is only preliminary. NPDES Permit Staff Report WSRO recommends this application for discharge be handled in accordance with Division guidelines.
