Unaltered shorelines along natural lakes, ponds and bayous are high probability areas for containing prehistoric archeological deposits. Two sites are recorded on Eagle Lake in the Big Hill Unit and one site is recorded on the Hillebrandt Unit on the shore of Hillebrandt Bayou. Public hunts for alligators are conducted by special permit during the September alligator season. Fishing is a popular public use benefit of the management area, particularly for large mouth bass and sunfish. Public access to much of the area is restricted to boats due to the lakes, bayous and marshes associated with this property.
Pipelines are common to all units of the Area.
Surface use agreements developed for mineral exploration and development are to repay the impacts to wildlife and habitat on the Area. Past research on the WMA includes a long history of waterfowl banding activities in the '60s and '70s, collection of alligator census data, and meticulous collection of data from waterfowl through public hunt exit interviews. Vegetation baseline data collected within the Big Hill Unit has been collected at long term intervals to track wetland plant succession and diversity within the Unit. Continuous data collected on the WMA on alligator nesting census lines and alligator night counts has helped to justify management of alligators statewide in Texas and remove the American alligator from the Endangered Species list in 1983. Current research includes chemical control of Chinese tallow trees and other invading brush species within the Big Hill Unit.
