Kanna Dam

The concrete Kanna Dam extends 185 meters across the Kanna River, reaching a height of 45 meters with a secondary saddle dam northeast of the main structure.

Engineers initiated the construction of Kanna Dam in 1982 following extensive studies conducted between 1973 and 1978, completing the project in 1992.

The dam integrates environmental considerations through fish ladders that enable local aquatic species, including fish, shrimp, and crabs, to maintain their migration patterns.

The reservoir created by Kanna Dam holds 8.2 million cubic meters of water, serving the regional needs for water supply and flood control across 8 square kilometers.

Mangrove restoration projects upstream from the dam created new habitats for waterfowl, enhancing the ecological value of the water infrastructure.
