are now leaving Lees Ferry water oxygen-starved. Warmer water has less dissolved oxygen, and the reservoir’s sinking surface elevation is causing flows through the dam’s tunnels to warm.WATER SHORTAGES:Low oxygen levels can stress and kill trout or force them to move downstream past where riffles add oxygen back into the flowing water.

A second treatment may be necessary within two months if more invasive fish are found to have hatched or hidden in the area’s dense vegetation.
