Big Sage Reservoir and campground are surrounded by juniper woodland and sagebrush. The reservoir is several thousand acres and the campground lies on the shore near the boat ramp.
From Alturas travel west on Hwy 299, 3 miles. Turn north on Crowder Flat Rd/County Road 73, and travel 6 miles. Turn right on County Road 180 and go 3.5 miles to Big Sage Dam and the campground.
Campground was OK, but the lake was pitiful. Overall it was a bit too bleak.
Dirty water, can't swim there. Roads around campsites are really rough. Just a really dusty place to try and spend the day. The bathrooms are kept very clean.
BLM land. Parking pads, picnic tables, fire rings, all new. Vault toilet, clean. Low usage. Road on left before GPS entrance is new entrance. Old one is blocked by boulders. You can get in but road is rough and low branches. New entrance is no problem.
