Williams Fork Reservoir is a large, high-elevation impoundment managed by Denver Water in Grand County, located between the towns of Parshall and Hot Sulphur Springs along the Colorado River corridor. With a 4.4-star rating from 90 reviewers, this reservoir has built a loyal following over the past four decades thanks to its free camping, expansive open scenery, and reliable fishing opportunities. The landscape is treeless and wide open, offering dramatic sunrise and sunset views over the water but also exposing visitors to persistent wind that can make boating challenging and daytime conditions intense without shade.
Fishing at Williams Fork Reservoir targets several species, with northern pike dominating the warm-water fishery and lake trout reported in deeper sections. Trout and kokanee salmon have historically been present, though multiple reviewers note that fishing quality has declined in recent years and northern pike predation has reduced trout and kokanee populations. Shore fishing is limited because the water stays shallow near the banks at roughly four feet deep except along the old river channels, making a boat the most effective approach. Ice fishing draws a dedicated winter crowd, and anglers describe it as a difficult but rewarding experience on the frozen reservoir. Paddleboarding is another popular on-water activity during calmer morning and evening hours.
Camping at Williams Fork Reservoir is free and managed by Denver Water, which has provided vault toilets, a dump station, and a boat ramp. No potable water is available on-site, so visitors must bring their own supply. Camping is dispersed-style with spots spread primarily along the southeast shoreline, each equipped with a picnic table and fire ring. A campfire ring is required to have a fire. The 14-day camping limit allows for extended stays, and many sites accommodate RVs and large trailers. Reservations are now required. Vault toilets are well-maintained and consistently stocked. The biggest campground drawback is the lack of trees and shade, so sunscreen and sun protection are essential.
Because this is a Denver Water supply reservoir, body contact with the water is technically prohibited, though enforcement appears inconsistent based on visitor reports. The mosquito population is notoriously heavy from late spring through fall, and visitors unanimously recommend bringing strong bug spray. Wind is the other constant companion, blowing hard during the day and calming in the evening. Eagles and other wildlife frequent the area, making bird watching a worthwhile addition to any visit. Biking along the reservoir roads is popular, and dogs must remain on leash. Hot Sulphur Springs is the nearest town with restaurants, a motel, a gas station, and the historic hot springs, while Kremmling sits about 16 miles away for larger resupply runs. Granby and Winter Park offer additional services further afield.
