Building dam is not an easy task. First you should calculate the quantum and force of water flow - min and max spread over 12 months.

The dam wall has to withstand the hydraulic pressure and also you have to design a gate to let the water flow out.

Thereafter you have to check the soil underneath which will be the host to the wall foundation. Depending on soild strength the depth has to be determined.

Its a long process.

wish you luck.
