Mill Hollow Campground Professional Review and Guide
"In the farming- and ranching-heavy West, where “whiskey is for drinking and water is for ﬁghting,” Mill Hollow Reservoir is something of an odd duck. Created in 1962, it’s maintained by the Department of Wildlife Resources and Uinta-Wasatch-Cache National Forest for recreational use. Where many other reservoirs capture water from early-spring runoﬀ
and release it slowly over the course of the summer for irrigation, water is never released from Mill Hollow for agriculture.
As a result, this is a tremendously popular family ﬁshery. Crowds are heavy, but the hatchery truck makes frequent stops to deposit catchable-sized rainbow, brook, and tiger trout. From the end of June through August, the lake is planted about once a week with one or more of those species, which average about 10 inches at planting time. While the reservoir has winter-killed in the past, most years it does not, and any holdovers will start reaching the 14- and 15-inch-plus range."
