Acton Lake is a 253-hectare impoundment located in a heavily used state park in southwestern Ohio. The length from inflow stream to spillway is 4.3 km, the total shoreline length is 13.9 km, the mean depth is 4.3 m and the maximum depth is 10.4 m. Sediment accumulation averaging 0.023 m annually provide a possible useful life of the lake for recreation of about 140 years. The lake stratifies chemically and thermally in the summer. Oxygen depletion occurs at the lower depths in the summer. Chironomids are the most numerous component of the macrobenthic fauna of the whole lake and chaoborids are quite abundant in deeper waters. The wet-weight benthic biomass is greatest in late winter before spring emergence. Funnel trapping has yielded a total of 1400 organisms per square meter for the emergence season from early spring to late fall. Annelids and pelecypods appear to have been increasing in numbers in recent years.
