Need environment friendly methods of making pond surfaces less pervious


We are planning to make shallow pond of 10 kottahs (1 kottah = 720 sqft). The location is near Bolpur in West Bengal. The soil here is of lareite kind and water percolation is high.

Can anyone suggest an environment friendly way to make the pond pit less pervious. I am not in favor of using plastic sheets or concrete. Do you think if the bottom of the pond is smeared with cow compost and vermicompost and some underwater plants are grown, water seepage can be reduced? Any suggestion will be highly appreciated.
