Abstract

Species native to Big Creek Lake prior to impoundment included smallmouth bass, largemouth bass, green sunfish, black bullhead, river carpsucker, white sucker, creek chub, carp, common shiner, and several species of Notropis. In addition, largemouth bass, bluegill, black crappie, walleye, muskellunge, channel catfish and blue catfish were planted in 1972 and 1973. During 1973 fish populations were sampled with pound nets, experimental gill nets, and seine net hauls to determine relative abundance, species composition, size structure, and some vital statistics of several species. Electrofishing was used to capture largemouth bass for tagging and numerical estimation of the population size. The Fish Management Branch of the Iowa Conservation Commission conducted a creel survey from which exploitation, harvest and angler success was estimated.
