Thottapally Spillway

Located about 20 kilometres south of Alappuzha town, the spillway at Thottappally was built in 1954. Due to southwest monsoon, floodwaters used to accumulate in the rivers of  Kuttanad  making a second crop during autumn impossible. The spillway was constructed to solve this problem by diverting floodwaters directly to the Arabian sea. The National Highway 47 passes over this spillway.
