Abstract
Two lakes having similar soil types were studied to determine the effects of age and water fluctuations on plankton, benthos and fish populations. Bluff Lake is an older man-made lake which is drawn down in the mid-summer in order to encourage food plants for waterfowl. Oktibbeha County Lake is a young lake and the water levels are maintained. Net plankton populations in Bluff Lake and Oktibbeha County Lake were comparable when analyzed on a number of organisms per liter basis. Peak populations occurred in both lakes in the fall. There was a spring, peak in Bluff Lake but none occurred in Oktibbeha County Lake. Fluctuations of water levels did not seem to have an effect on the net plankton populations. The benthic population in Bluff Lake is slightly higher than that found in Oktibbeha County Lake. Based on one-acre samples from each lake, Bluff Lake has a more balanced fish population than does Oktibbeha County Lake. Bluff Lake contains a high population of small and intermediate sized white crappie and bluegill. The bass population seems low. However, other predator fish such as flathead catfish and spotted gars are found in adequate numbers to help bring the lake toward a more balanced condition. (Author)
