(Monday 6 of the 7 basin states issued a model)...The model has recommendations on controlling the current drought along the Colorado River Basin. 

The Colorado River is in a prolonged and severe drought. The Bureau of Reclamation has asked the seven basin states that rely on the Colorado River Water to come up with a plan. The model released Monday was approved by 6 of the 7 Basin states. California, with the largest allocation of water, said they would release their own model. That was released Tuesday. The model was put together by the California Colorado River Board, after meeting with the California Water agencies using Colorado River Water. They proposed a modeling framework for the Bureau of Reclamation to evaluate as it considers actions to help stabilize reservoir elevations and protect critical infrastructure to ensure the Colorado River system can continue to support 40 million people, nearly 6 million acres of agriculture, and tribes across seven states and portions of Mexico. The California Model outlines a constructive approach to achieve additional water reductions while protecting infrastructure, prioritizing public health and safety, and upholding the existing body of laws, compacts, decrees and agreements that govern the Colorado River operations, known as the law of the river.
