Boulder Creek is a small creek that holds a variety of fly fishing opportunities. The river begins up in Indian Peaks Wilderness and works its way down through the heart of Boulder, Colorado. Boulder Creek provides opportunities to fish high-gradient pocket water, as well as managed runs and pools through town that have been created for kayakers. The river contains primarily browns, with an increasing population of rainbow trout. In addition, brook trout are caught on occasion, and higher up above Barker Reservoir, greenback cutthroats can be caught along with the occasional grayling. Trout range from 8-16 inches with an average fish being 10-13 inches. With Boulder Creek being so close to Denver and the rest of the suburbs of Colorado, it’s a great river to fish for a day, where even beginner anglers have an above average chance to catch a lot of fish.
