Twenty-three scholars from Western universities sent a letter Tuesday to Interior Secretary Sally Jewell.
Owen Lammers, executive director of Living Rivers and Colorado Riverkeeper, says the federal government needs a wider breadth of scientific research to ensure it is prepared for all water flow scenarios for the next 50 years. His group believes the government is relying on opportunistic projections.
Secretary Jewell is expected to receive the letter Wednesday.
