About Thompson Reservoir Campground

Overview

Located 40 minutes south of Silver Lake, Oregon, Thompson Reservoir Campground is a developed campground ideally situated on the three-square-mile reservoir with pretty vistas of nearby Hager Mountain. There are 19 campsites with picnic tables, fire rings. Other amenities include hand-pumped water, and three vault toilets. There is also one large group site.

Tall ponderosa pines and a few aspen trees lord over the high mountain setting of Thompson Reservoir. Recreation opportunities include fishing, hiking, and exploring. The reservoir is stocked once a year with rainbow trout and there is a boat launch.

This campground typically opens mid-May and closes mid-October. Heavy snowfall prevents this campground from being used in the winter and early spring.
