Marshall Lake

Marshall Lake sits in the eastern foothills of Boulder County, just a short distance from the towns of Louisville and Superior. If you have stumbled across this lake while scanning a map of Front Range water, you should know upfront that Marshall Lake is privately owned and operated by the Louisville Rod and Gun Club, a sportsman's organization established in 1952. Public access is not available, and visitors who arrive without membership will be turned away at the gate.

The club manages roughly 30 to 40 acres of water surrounded by rolling grassland and foothill terrain. Members of the Louisville Rod and Gun Club enjoy year-round access to a quiet retreat that feels miles from suburban development even though it lies fewer than two miles from town. The lake holds populations of rainbow trout, cutthroat trout, largemouth bass, smallmouth bass, bluegill, crappie, and carp, giving anglers a diverse fishery rarely found on the Front Range. Members report solid catch rates for trout throughout the cooler months and warm-water species during summer.

Beyond fishing, the property offers mountain biking on singletrack trails that wind through the foothills, primitive camping for overnight stays, and hiking routes with sweeping views of the Continental Divide. Club events and organized outings run throughout the year, building a tight-knit community of outdoor enthusiasts who value the privacy and stewardship the club provides. Livestock graze the surrounding open space, so visitors should expect to encounter cattle along the access road.

Because Marshall Lake is a private facility, there are no public restrooms, boat ramps, or maintained trailheads. Anyone interested in gaining access must become a member of the Louisville Rod and Gun Club or receive a personal invitation from a current member. Membership is typically obtained through nomination by an existing member. If you are searching for public fishing opportunities nearby, consider Walden Ponds, Sawhill Ponds, or Boulder Reservoir, all of which are open to the public and located within a short drive.
