About the Interstate Stream Commission (ISC)

The Interstate Stream Commission has broad powers to investigate, protect, conserve, and develop New Mexico’s waters including both interstate and intrastate stream systems. The eight unsalaried members of the Commission are appointed by the Governor. The ninth member is the State Engineer who under state law is the secretary of the Commission. The Interstate Stream Commission Director serves as the deputy state engineer.

The Commission’s authority under state law includes negotiating with other states to settle interstate stream controversies. New Mexico is a party to eight interstate stream basins. To ensure basin compliance, Interstate Stream Commission staff analyze, review, and implement projects in New Mexico and analyze streamflow, reservoir, and other data on the stream systems.

The Commission is also authorized by statute to investigate and develop the water supplies of the state and institute legal proceedings in the name of the state for planning, conservation, protection and development of public waters.
