Based on information available on the official website of Butte Lake Campground, the boat ramp at the campground is a concrete ramp that provides access to Butte Lake. The ramp is reported to be wide enough to accommodate most boats.

Butte Lake is a natural lake located in the Lassen National Forest in northeastern California. The lake covers an area of approximately 250 acres and is fed by creeks and springs in the area.

According to the website, motorized boats are allowed on Butte Lake, but only at a maximum speed of 5 miles per hour. Non-motorized boats such as canoes, kayaks, and rowboats are also allowed on the lake.

It is important to note that due to the ever-changing nature of recreational facilities, it is always best to check with the appropriate authorities for the latest information on any boat ramp or water body.
