Requires the Secretary to provide for development of a comprehensive plan for the San Acacia and Isleta reaches to plan, design, construct, and prioritize projects that balance river maintenance, water availability, use, and delivery, and ecosystem benefits.

Requires the Secretary of the Army to continue, for five years after enactment of this Act, the temporary deviation in the operation of Cochiti Lake and Jemez Canyon Dam that was initiated in 2009 and terminated in 2013, to evaluate the benefits of the deviation while a permanent reauthorization of the reservoirs is pursued.
