Delta, Utah is roughly 40 miles upstream from Sevier Lake. Sevier Lake is dry. The picture above shows one of the reasons.
Delta is an agricultural town on the Sevier River, which would drain into Sevier Lake if Delta didn’t use most of the river’s water for irrigation. Delta is surrounded by lush farm fields, to the substantial benefit of the town.
When Sevier Lake was first observed by settlers in 1872, there was water in it, but it turns out that has rarely occurred since. What you see in the picture below is called Sevier Lake, but it is actually the dry surface of an ancient lake in the Sevier Desert.
The lake did have water in it In 2011. It was a year with a lot of rain, and upstream reservoirs dumped excess water into the river. As a result the lake reached a depth of … three feet.
Lately, the dry lake has been found to contain potassium sulfate, which is used in fertilizer, so there may be mining here in the future.
