President Donald Trump’s nomination of a Bureau of Reclamation veteran to head the agency with primary responsibility on the Colorado River won the endorsement of U.S. Rep. Scott Tipton and a cautious reaction from U.S. Sen. Cory Gardner, both Republicans. Brenda Burman is an excellent choice with a strong background in Western water issues, Tipton’s office said. Much of the river’s course in Colorado runs through Tipton’s 3rd Congressional district. “There is no question that Ms. Burman has significant expertise and history in Western water issues, particularly in the Colorado River Basin,” Gardner said in a statement.
