The Thanneermukkom Bund (Thannermukkom Salt Water Barrier) was constructed as a part of the Kuttanad Development Scheme to prevent tidal action and intrusion of salt water into the Kuttanad low-lands across Vembanad Lake between Thannermukkom on south and Vechur on north. Thanneermukkom Bund was constructed in 1974 and is functional since 1976. It is the largest mud regulator in India.
