Document Summary
Dams & increasing supplies: which province is currently facing opposition against a proposal for a dam and hydroelectric generating station, built on its peace river, alberta, quebec, new brunswick, british columbia. Water in the reservoir can evaporate more easily. There is a net loss because water taken for irrigation is not usually returned to the river. World commissions on dams estimate that about 60% of effects of dams are unintended by planners. Dams such as the condit dam in washington state (~1910) have great historical significance. They have allowed irrigated agriculture by storing water in periods of god supply therefore converting flood hazard into a usable resource by accumulating river flows until further needed. They have also contributed to urban development. In the modern world they are essential developments large-scale water diversions. The upstream face is facing the reservoir where the water is being stored.
