Mundel Lagoon

Mundel Lagoon
Mundel Lake or Mundalama Wewa (Sinhala: මුන්දලම වැව; Tamil: முந்தல் குடா) is a shallow brackish water lagoon located in Puttalam District, Sri Lanka.

Physical, ecological features & climate
The lagoon covers approximately 3,100 ha of area fringed by mudflats, salt marshes, sand dunes, and mangroves clusters (IUCN & CEA, 2006). It is completely cut off from the sea by a narrow sandbar at Udappuwa and is connected with the Puttalam estuary at the northern end through a long and narrow channel system, the Dutch canal (IUCN & CEA, 2006; Jayasiri et al., 1998). The length of the Dutch Canal from Puttalam lagoon to Mundel Lake is 16 km and its width is about 10 m (Jayasiri & Rajapaksha, 2000). Freshwater enters the lagoon through a seasonal river named Battulu Oya (Jayasiri et al., 1998). The surface area of the lake is approx. 30 km² at the local mean sea level and the mean depth is about 0.75 m (IUCN & CEA, 2006; Jayasiri & Rajapaksha, 2000).

The lagoon is located within the dry zone of the country and experiences two rainy (April-June and October-November) and two dry periods per year (IUCN & CEA, 2006). The average annual rainfall is 1,000-1,500 mm and the temperature is uniform at around 30.4-33.6 ℃ (IUCN & CEA, 2006).

The wetland is mainly used for fisheries and prawn farming and as a result of the excessive utilization of the resources beyond the sustainable limit, the wetland system has been disturbed today.
