About this campground
Nestled along the pristine southern shores of Reservoir Lake, this high-elevation retreat offers an intimate camping experience where 16 thoughtfully placed sites blend seamlessly into the landscape of towering pines and aromatic sagebrush. At 7,000 feet above sea level, Reservoir Lake Campground provides a perfect balance of wilderness solitude and modern conveniences, including fresh drinking water, accessible vault toilets, and bear-resistant food storage to ensure both comfort and safety. Each campsite comes equipped with its own picnic table, while a primitive boat ramp invites anglers and paddlers to explore the tranquil 11-acre lake, where only electric motors disturb the mountain silence.
Reservoir Lake Campground offers a mix of tent and combined sites, suitable for traditional camping experiences. The sites are distributed among mature pines and sage, providing a rustic and natural setting.
Weather and SeasonsThe high-altitude climate here tells a story of dramatic seasonal transitions. Early season visitors might wake to frost-kissed mornings and snow-dusted pines, while summer transforms the campground into a sun-drenched paradise with crystal-clear days perfect for lakeside adventures. As autumn approaches, the weather becomes increasingly unpredictable, with temperatures that can plunge from comfortable afternoon warmth to near-freezing nights. Late summer emerges as the sweet spot for many campers, offering reliably warm days under brilliantly blue skies that seem to stretch endlessly above the mountain landscape.
ElevationPerched at 7,000 feet in the heart of the mountains, Reservoir Lake Campground offers the authentic high-country experience that mountain lovers seek. This significant elevation creates a cooler, more refreshing climate even during summer's peak, though visitors should prepare for the thin mountain air that can leave newcomers slightly breathless during their first day or two. The altitude enhances every sunset and sunrise, painting the sky in colors that seem more vivid than anywhere at sea level.
Natural Features and SceneryPicture yourself waking to the gentle lapping of water against the shoreline, surrounded by a living tapestry of emerald pines and silver-green sagebrush that carpet the rolling hills. The centerpiece of this natural sanctuary is the 11-acre Reservoir Lake, its mirror-like surface reflecting the surrounding forest and sky in perfect detail. The mature pine groves provide natural shade and privacy between campsites, while the native sagebrush fills the air with its distinctive desert perfume after summer rain showers. This harmonious blend of forest and high desert creates a unique ecosystem where mountain and prairie landscapes converge.
Geological RegionReservoir Lake Campground sits within the magnificent expanse of the Beaverhead-Deerlodge National Forest, where ancient geological forces have sculpted a dramatic landscape of pine-covered ridges and sage-dotted valleys. This high-elevation lakeside environment represents millions of years of natural history, from volcanic activity to glacial carving, resulting in the stunning alpine lake that serves as your backyard during your stay. The surrounding hills showcase the region's complex geology, with exposed rock formations telling the story of the Earth's dynamic past while providing a spectacular backdrop for outdoor adventures.
