Begin Conservation on a lake in Nepal

I am currently working in Nepal for a couple of months and this is the project:

Taudaha is the only remaining living lake that sustains the birdlife though there are other two such lakes in Kathmandu valley. This lake not only holds its important in terms of nature but is equally important historically, socially, economically and ecologically.

Any suggestions or advice to how i can begin to protect and begin conservation on this lake??

Many thanks  :-)
