Twenty-three designated swimming beaches, two informal swimming areas, and four canoe launching sites were sampled at least ten times during a 30-day period in 1990. All 29 met the regulatory limits of a geometric mean of less than 200 colonies of fecal coliform bacteria per l00 milliliters (ml). However, four sites had one sample each with at least 1000 colonies per 100 ml, which is a violation of recreation criteria in two of the seven Tennessee Valley states. Forty-four nonrecreation sites were also sampled to provide generic bacteriological water quality data on several reservoirs and streams and to determine if the Georgia Mountain Fair was having an adverse impact on the bacteriological water quality of Chatuge Reservoir. No impact was observed. Thirty-three sites on 15 reservoirs were sampled, and all but three met recreation criteria. Eleven locations were sampled on three streams: Cotaco Creek near Huntsville, and Beaver and Bullrun Creeks near Knoxville. A comparison of 1990 sampling results at 16 sites with results from a 1974 survey was made.
