The objectives of the current phase for the Houma Navigation Canal (HNC) Lock Complex (TE-113) will complete design, engineering and feasibility assessments that will reduce salt water intrusion and distribute freshwater within the Terrebonne Basin. It is estimated that the design will consist of a lock that provides 110’ of clear width and an 800’ long Lock Chamber and a floodgate that provides 250’ of clear width with integral sluice gates and closure walls to connect to existing flood protection features. This project will help to limit the intrusion of salt water into freshwater marsh systems allowing for the maintenance of thousands of acres of wetlands which serve as critical wildlife habitat and nurseries for fisheries. The HNC Lock Complex will also provide crucial flood protection by blocking storm surge as a key component of the Morganza to the Gulf Hurricane Protection Project.
