Flaming Gorge Dam: The Good, the Bad & the Beautiful
When Flaming Gorge Dam was built, it changed the life-cycle of the river. Water was released from the bottom of the dam, so it flowed cold and clear year-long. Releases fluctuated daily, and sometimes hourly, because water levels were controlled by power and storage needs rather than natural rhythms. Spring flooding was controlled. Some wildlife, especially native fish, suffered, since they were not adapted to a river controlled by a dam or to the reservoir it created. A few wildlife species benefitted. Osprey habitat was enhanced by the creation of a clear-water reservoir. Trout also thrived in the cold, clear water. In fact, the tailrace is now considered an international Blue Ribbon trout fishery and the reservoir has produced more than its
“May 30. —The opposite wall is a vast amphitheater… Each step is built of red sandstone… The amphitheater seems banded red and green, and the evening sun is playing with roseate flashes on the rocks, with shimmering green on the cedars’ spray, and with iridescent gleams on the dancing waves. The landscape revels in the sunshine.
May 31. —Today we have an exciting ride. The river rolls down the canyon at a wonderful rate with no rocks in the way we make almost railroad speed.”
—John Wesley Powell, 1869
Restoring a Better Balance for Fish
More recent modifications to the dam and its management have also helped wildlife. Today, release temperatures can be regulated by taking water from any depth, which enhances trout habitat. The highly fluctuating flows for power generation are moderated by agreements which enhance habitat for native fish.

The expedition, which lasted approximately three months during the summer of 1869, embarked from Green River Station, Wyoming Territory and traveled downstream through parts of the present-day states of Colorado, Utah, and Arizona before reaching the confluence of the Colorado and Virgin rivers in present-day Nevada. Despite a series of hardships, including losses of boats and supplies, near-drownings, and the eventual departures of several crew members, the voyage produced the first detailed descriptions of much of the previously unexplored canyon country of the Colorado Plateau.
