- Site description: Although relatively small, this is a highly productive trout stream located in Millard County. Utah Division of Wildlife Resources surveys verify reports of brown trout over five pounds, along with abundant numbers of smaller trout. Surveys have documented trout standing crops of over 300 pounds per acre, compared to 50 pounds per acre for an average western trout stream.
Numerous springs and a high water table keep this stream from freezing during the winter and provide winter habitat for large trout. The stream is occasionally subject to flash floods. Extremely high winter snow packs in 1983 and 1984 caused excessive spring runoff which gutted the stream channel, killed most of the fish, and removed most trout habitat. The Division and the Forest Service combined efforts in 1986 and 1987 to reconstruct much of the stream channel and replace much needed trout habitat. The trout population responded and good fishing quickly returned. If anything, regrowth of vegetation on stream banks has been too successful, making much of the stream difficult to fish, especially if casting flies is preferred.
About five miles up the canyon, the road turns south away from the upper section of stream and offers an opportunity for walk-in access of about a two-mile hike to Big Spring. This area is also more open making for easier fly fishing.
Tributary streams include Second Creek and the North Fork. The lowermost section of Corn Creek, just outside of the canyon, is on private land. Make sure you have permission before trespassing. The Division stocks some catchable-sized rainbow trout near the campground.
Corn Creek is noted for occasional infestations of Mormon Crickets. Swarms of these large insects can cause trout to go on massive feeding frenzies. If you are lucky enough to encounter such a situation, expect a truly unique fishing experience.
Besides flies, natural baits and spinners can be effective methods to catch brown trout. A number of other nearby fisheries are further south, including Clear Creek and other small streams and lakes on the Beaver Mountain. Just to the north, Chalk Creek and Oak Creek are located near Fillmore and Oak City, respectively.
