History and purpose of Lake Powell
As a person who cares deeply about the preservation of natural spaces and ecosystems, I have mixed feelings about the very existence of Lake Powell, America’s second-largest man-made lake. Electricity is the main purpose of creating dams, and the huge lakes behind them. While dams often created ecological "situations," downstream, they have become essential for powering basically every large city in the West. The lake gets its name from Major John Wesley Powell, a Civil War veteran who, in 1869 explored the Green and Colorado rivers along with eight other people. Almost a century later, the Glen Canyon dam was completed, and the Lake Powell began filling up in 1963. It took seventeen years to fill the giant bathtub of bright red rock, and today it’s over 500 feet deep in some spots. The water levels fluctuate pretty dramatically depending on spring snowmelt, and the water/electricity requirements that determine how much water must be let out to spin the dam’s eight massive generators.

My Lake Powell Fishing Trip
These guys are serious. And even when the fishing is not so good, they know how to catch fish. For example, when we arrived at Lake Powell, conditions were not good for fishing because the lake was “turning over,” which is a phenomenon that occurs on most lakes in the spring. During the winter months, the deeper parts of the lake are the warmest, but when the lake turns over, the colder water ends up at the bottom, while the warm water comes to the top, bringing with it a lot of algae. This inversion makes fishing poor for two reasons; First, the algae makes water visibility bad and second, the change in water temperature throws fish off from their normal behavior patterns, since temperature often determines what depth the fish like to be. Fortunately lakes, no matter what their size, usually “turn over” very quickly. So, while the fishing was slow at the beginning of our trip, by the last few days the water had cleared up and the temperatures had stabilized, and we were up to our gills in stripers and largemouths. You won’t see many fishermen or tourists along the shores of Lake Powell. This is not only because you’d need a lot of line to drop you bait down 600 feet of cliff face into the water, but also because the surrounding “slickrock” terrain is not accessible by any roads. And although thousands of people visit the lake on any given weekend, it’s big enough that you won’t see many of them. If you’ve parked your houseboat in one of the fingers of red rock, you might wake up to see a coyote, bobcat or mule deer trotting along the water’s edge or, if you’re lucky, you’ll see a desert bighorn sheep defying gravity, making its way across the face of a vertical cliff. We didn’t see any sheep on our trip. But we caught a lot of fish, drank a lot of beer, and thought gosh dang-it, maybe this lake wasn’t such a bad idea after all.
