Highest bird population was observed in the months of January and February. Various birds including little grebes, painted storks and purple moorhen can be spotted in this lake.
Fishing is carried out by local fishermen and enthusiasts. In the 2000s, due to encroachment and the fishes were infected with metals and pathogens from polluted waste water discharged from the sewage. The local fishermen requested the lake to be cleaned up to ensure healthy fish population.
The lake became contaminated with effluents from sewage release from the city and was encroached by water hyacinth. In 2010, Coimbatore Corporation unveiled a plan to De-silt the lake and clear the encroachments. The corporation hired external consultants and suggested public-private-partnership model for the development of the lake. In 2013, the de-silting was carried out by the Coimbatore Corporation in association with NGO Siruthuli, Residents Awareness Association of Coimbatore and Vijayalakshmi Charitable Trust. The restoration of the lake was funded partly by the government and partly by private corporations and the activity was carried out with the help of volunteers from public.
In 2015, the Coimbatore corporation announced a beautification project at the cost ₹49.5 million (US$690,000). The civic body planned to lay a 1.2 km (0.75 mi) stretch of road exclusively for two-wheelers and beautify the tank bund by installing solar powered lamps and steel fences. The road was inaugurated on June 8, 2015 by the Chief Minister of Tamil Nadu and helped ease traffic congestion in Ukkadam area. It is also known as Marine drive of coimbatore
