Bait fishing is allowed at Kolob Reservoir through Sep. 12, 2025. Our spring netting survey found abundant rainbow, tiger, and cutthroat trout, with a handful of brook trout mixed in. Most Rainbow Trout were about 10-15 inches and 0.50-1.50 lbs, while Cutthroat Trout and Tiger Trout tended to be larger with most between 15-22 inches and 1.50-3.50 lbs and a few over 22 inches and 4 lbs. Remember that the trout limit is two fish under 15 inches or over 22 inches. Recreation use at Kolob Reservoir is administered by the Washington County Water Conservancy District and dramatic increases in visitors during recent years has prompted the district to employ new regulations to allow them to properly maintain the surrounding land and mitigate abuse. Camping fees are required and boats are limited to 10 horse power motors. Please respect these regulations so that recreational access can be maintained at Kolob Reservoir.
