Michael Hadley, an aquatic biologist for the Utah Division of Wildlife Resources, sent in this report of a gillnetting survey at Koosharem Reservoir last week.
Koosharem Reservoir: On May 1, UDWR found healthy rainbow, cutthroat, and even a few brook trout in Koosharem. Most trout were 14 to 17 inches in length, with the biggest at 21 inches and four pounds. Trout numbers were not high, but the fish were in good condition. Utah chubs, however, were very abundant, making up a significant portion of the fish biomass sampled during the survey. With such a high density of chubs, fishing is often tough at Koosharem, but patient anglers willing to put in some time can give themselves a chance to land a trout exceeding 5 pounds.
