Why do the rivers fail to benefit the state to an extent they should have ?

Rivers fail to benefit the state to an extent they should have. Because,
1) there are no sufficient structures (dams) to store river water.
2) over usage of water by the other states.
3) geographically our rivers are flowing through the rocky and hill areas in most of the places in our state where it si difficult to make canals.
4) government should plan for proper utilization of river water after scientific study with the help of expert engineers.
