Reservoir |
|
The Gregory Lake is a reservoir in the town of Nuwara Eliya in central Sri Lanka .
geography
It has a length of about 1.2 km and measures at its widest point about 600 m with an extension of 30 hectares. The Thalagala Oya, a tributary of the Nanu Oya, is dammed in it in the upper catchment area of the Mahaweli .
Naming
The lake was laid out in 1873 by then British Governor Sir William Henry Gregory and for a long time served as the basis of a hydroelectric power plant.
Pollution and usage
Despite its proximity to the source, the water is badly affected by agriculture and tourism and tends to eutrophicate (... the lake is in a persistent meso to eutrophic state). Its cadmium content of 13.6 µg / l also makes it only conditionally useful for the production of drinking water. Today the lake is used exclusively for local recreation.
