Site description Carambolim lake lies in Ilhas taluka, about 12 km from Panjim, the capital of Goa. It is spread over an area of 70 ha, of which 40 ha is under water for most of the year. In order to grow paddy, a number of minor irrigation tanks have been developed in Goa. These tanks are made by the impoundment of run-off during the monsoon. They are also a natural source of fish, because every year, before the monsoon, the remaining water is drained out to empty the tanks and the fish are harvested. The sluice gates of Carambolim lake at the southeastern side are kept closed from late July to early May next year. The impounded water is used for irrigation of paddy fields in the lower reaches on the southern side of the lake (Shanbhag et al. 2001). The western embankment of the lake serves as the base for the recently laid Konkan railway track, while the eastern side has been partially cleared of its scrub forests, mango and cashew groves, to pave the way for the construction of residential buildings. Coconut and mango trees fringe the remaining sides of the lake. The water depth is between 1.5 m to 3 m, depending upon the season. The lake lies between the estuarine zone of the Mandovi and Zuari rivers. The main vegetation consists of Nymphea stellata, a rooted plant with floating leaves, Oryza rufipogon, an emergent wild paddy, and submerged Hydrilla verticillata.
