Abstract : This report presents the results of the initial poststocking period covering a 12-month period from September 1977-August 1978. The data collected during this period were compiled in a format similar to that used for the baseline report. The compiled poststocking data were compared to the baseline conditions to determine if any substantial changes had occurred. The baseline report concentrated on certain water quality factors for future data comparisons. These included concentration variability due to sampling depth, water quality variability between the five lake pools, phyto-plankton and nutrient relationships, and seasonal variations in water quality. Each of these factors is reviewed in this report, and changes which have occurred compared to the baseline period are documented. Concerning variations with changing sampling depths, three parameters were found to have greater than a 5 percent variation in mean value at different depths. These parameters include organic nitrogen, biochemical oxygen demand (BOD), and volatile suspended solids. The baseline report established a trend of increasing water quality proceeding from Lake Gatlin to the South pool of Lake Conway. During the poststocking period this trend changed somewhat in that the pools associated with Lake Conway exhibited similar water quality conditions compared to each other. However, Lake Gatlin continued to have the poorest water quality.
