Comment Blow up Glen Canyon Dam (Score 1) 172
Removing Lake Powell would only be a stop gap measure, but it would save Lake Mead for a few years. What needs to happen is to re-allocate the Colorado River water based on current drought levels (not on the 1930's above average levels) and change how farmers use water. Agriculture uses far more water than cities. Also stop growing crops that use a lot of water in the desert. Farmers will adapt if given the right incentives like subsidies to switch from wasteful flood irrigation to more efficient forms. It doesn't help that we are draining the aquifers in the southwest causing subsidence and fissures in the land. Ultimately, big cities like Phoenix will have to be abandoned because of global warming.
