Burnell Lake, also known as Sawmill Lake, sits in the hills near Oliver, BC, in the Okanagan-Similkameen region. The lake is reached via the Sawmill Burnell Lake Forest Service Road, accessed from Willowbrook Road off Highway 97.

The gravel road involves a modest climb and has some washed-out sections and rocky stretches, though it is generally passable by two-wheel-drive vehicles.

The Burnell Lake Recreation Site is a high-use destination popular for camping, fly fishing, and dirt biking. The lake is fly-fishing-only for trout, with rainbow trout the primary catch.

Several primitive campsites are spread around the lake, along with pit toilets and a boat launch. The site sees heavy use during peak season but can be quiet at other times of year.
