What is lake tapping ? Why it takes place ?

Explanation

A lake tap involves excavating a tunnel at the bottem of the lake. Dynamites are planted therein and blasted carefully. The water flows with greater force through the tunnel after such blasting is done. This increased flow of water is then driven to the hydroelectric power generation plant for increased electricity production. This technique is done to establish waterways for hydropower, for making drinking water available, for irrigation water purposes and also for the landing of oil and gas popes from offshore fields.
