Project Description

The project will reduce pollution and hydrologic degradation to coastal waters within the Choctawhatchee Bay Watershed by removing culverts under County Road 30A that are deteriorating and/or in disrepair, presently acting as barriers separating the north and south portions of Alligator Lake rather than allowing the exchange of fresh and Gulf waters. The culverts act as barriers to fish and wildlife and reduce water and sediment exchange. A bridge will be constructed across Alligator Lake to help restore tidal exchange and remove barriers to fish and wildlife movements. Specifically, the project will include: • Construction of a spanning bridge across Alligator Lake to replace culverts that are deteriorating and/or in disrepair; • Continued water quality sampling under an existing monitoring program. The project will help restore the connection and circulation of the lake and improve the lake community and adjacent ecosystems, improve water quality in the lake, and enhance fish and wildlife habitat. The project will directly improve water quality in watersheds injured by the Deepwater Horizon oil spill by restoring hydrologic connections between the coastal and freshwater portions of Alligator Lake and enhancing coastal habitats. By replacing culverts in disrepair with a bridge, hydrologic connectivity will be restored, resulting in improved water quality, water flows, and subsequent benefits to fish and wildlife. The project will develop and implement management actions to improve water quality in Alligator Lake and the Choctawhatchee Bay watershed by removing physical barriers from the lake.
