connected to it. Warabokka-ela stream (Koggala-oya) that enters the lagoon from the north-west is the main freshwater supply. Kerena anicut, which was constructed combining two streams, Mudiyansege-ela stream and
Thithagalla-ela stream, is the second largest freshwater inflow. Heen-ela stream contributes a minor to the freshwater inflow In addition to above four streams, Kahanda-ela stream, Gurukanda-ela stream and Thelambu-ela stream are also contributors for freshwater inflows but are presently abandoned with overgrown vegetation. The only outlet of the lagoon is Pol-oya located at the southeast corner; a narrow 300 metres (980 ft) long canal, which connects the lagoon with the Indian Ocean.

Pol-oya outlet near the lagoon mouth. The naturally built sand bar, which was perpendicular to the lagoon mouth controlled the seawater intrusion into the lagoon. With the opening of the lagoon mouth during the rainy season, rapid outflow of water began. However, the flow of seawater into the lagoon during the monsoon and high tides ceased the formation of sand bar again in the dry season. This natural dynamic rhythm causes high seasonal variations in most of the physical and chemical properties of lagoon water.

1995, the
Southern Provincial Council built a groyne system to protect the bridge from the wave attack. Another groyne was built in 2005 to control the erosion at the west side of the mouth due to prevailing groyne structure. Construction of the groyne provoked concern over local resource users and environmentalists as the lagoon hydrology and water quality showed drastic changes and variations.

After the removal of the natural sand barrier, the formation of sand bar shifted towards the “Kathaluwa” bridge (highway bridge) by exposing the bridge to wave attack. Breaching the sand bar became increasingly difficult and erosion close to the bridge posed a risk to the bridge. Subsequently, in
