Water use for Hydro-power generation will depend on the timely releases from reservoirs and will become a source for secondary usage such as irrigation and water supply schemes. There is an advantage in secondary use of water if the primary use is for Hydro power generation, as there will be no impurities that will be accumulated during in-stream use of water.
