Barker Reservoir is a mountain reservoir in Boulder County, Colorado, located within walking distance of the town of Nederland along Highway 119. Rated 4.6 stars, this scenic body of water sits in the high country between Boulder and Estes Park and serves as both a local landmark and a worthwhile stop for anyone driving through the Peak to Peak corridor. The reservoir is fed by Middle Boulder Creek, and its dam creates an impressive visual backdrop. Full-moon nights over the frozen reservoir have been called mesmerizing by visitors who stumbled upon it after dark.
Fishing at Barker Reservoir draws anglers who work the shoreline for trout. Brown trout have been caught both in the reservoir and in the creek above the lake. Fly fishing is the primary technique, with reviewers reporting success using dry dropper setups after finding streamers less effective in the shallow western shoreline near the main parking lot. Shore access for casting is limited in places due to dense evergreen tree cover along portions of the bank, so anglers should scout the western side first. Fishing results vary, with some visitors reporting productive days and others going hours without a bite, so expectations should stay moderate.
Hiking around Barker Reservoir offers a scenic walk along the shoreline trail, though only part of the perimeter is accessible on foot. The trail provides close-up water views and elevated overlooks of the reservoir and surrounding mountain landscape. About half a mile downstream from the reservoir, picnic areas sit along Middle Boulder Creek in a beautiful creekside setting that does not appear on most maps. Dog walking is popular along the shoreline, and the area is described as a great spot to bring pets for a stroll.
Barker Reservoir functions primarily as a day-use destination. No swimming is permitted in the reservoir. Overnight camping is not allowed at the reservoir itself, though one reviewer mentioned camping in the general area. Facilities are minimal: a porta potty, a picnic table, and a good-sized parking lot with direct water access. Shade is limited around the picnic area, so bring sun protection. Nederland's characteristic wind is a factor here, and a jacket is recommended even on warm days.
The reservoir is a short drive from Boulder, making it an accessible mountain escape for Front Range residents. Nederland offers coffee shops, breakfast spots, and restaurants within walking distance. The location also works as an acclimatization stop for visitors adjusting to altitude before heading higher into the mountains. The drive from Boulder follows a scenic canyon route, and the reservoir serves as a natural pitstop on the backroads connection between Boulder and Estes Park. Steep banks around portions of the reservoir make it unsuitable for small children near the water's edge. Visitors note occasional litter left behind by others, so pack out any trash to help keep the area clean.
