Pruess Lake is a small spring-fed lake in Snake Valley, Millard County, west-central Utah. It is just south of Garrison and north of Burbank. It was named after Charles Preuss, a cartographer who was on John C. Fremont's first, second and fourth expeditions. Where or when the spelling error (Preuss vs Pruess) occurred is unknown, but all maps and official state naming documents mention the lake's name as Pruess.
