Here is my perspective on The Drought Contingency Plan.
The Drought Contingency Plan (DCP) attempts to mitigate the reduction in lower basin water use by implementing certain conservation measures. Essentially finding a negotiated way to stabilize the Colorado River watershed. Lower basin states including Arizona use Colorado River water stored in Lake Mead. Lake Mead is at a critical level which which if not addressed could cause a "death spiral". This shortfall could occur in 2019 or 2020.
