About this spot

Williams Creek Reservoir

Williams Creek Reservoir, located in the San Juan Mountains of Colorado, is a prime fishing destination for anglers. The reservoir is home to rainbow, brown, and brook trout, making it a great spot for both fly and bait fishing. The nearby San Juan National Forest provides plenty of opportunities for hiking, camping, and exploring. The best time to visit for fishing is from late May through early October, with temperatures ranging from 65-80°F during the summer months. Anglers should try using small spinners or flies in the morning and evening for the best chance at a catch.
