Completed in 1966, Glen Canyon Dam was constructed as part of the Colorado River system to aid in the management of this precious resource. After the dam was built, it took 17 years for Glen Canyon to fill completely creating Lake Powell. Lake Powell and the surrounding area are part of the Glen Canyon National Recreation Area.
Lake Powell Bathtub Ring Fun Fact
One dramatic feature of Lake Powell is the distinctive line around the lake. This line is affectionately referred to as the Lake Powell bathtub ring.
The Lake Powell bathtub ring is a result of the significant drop in the water level. The lake was considered full in 1980 and since that time the overall water level has decreased.
Minerals deposited by the water created the Lake Powell bathtub ring. When the water level was up, calcium carbonate and other hard minerals in the water adhered to the rock. The line that remains provides a clear picture of the dramatic change in the lake level.
To be clear, I don’t think the drop in water level is positive! However, I find the remaining Lake Powell bathtub ring fascinating. I enjoyed the bleached appearance of the rock. The color contrast is quite striking!
On your next boat trip, be sure to pay extra attention to the Lake Powell bathtub ring! It is just one of many things that make this lake fascinating and such an amazing place to visit!
