An MOU was signed in December between the U.S. Department of Interior and Arizona, California and Nevada, which commits the lower Colorado River Basin states and DOI to investing up to $200 million over the next two years to save 500,000 acre feet of water (above the amount currently required in the Drought Contingency Plans) to preserve Lake Mead water levels.
In addition, Interior officials also signed agreements with Colorado River Indian Tribes (CRIT) and the Gila River Indian Community to stabilize the water elevation of Lake Mead.
