Lake Avery is a reservoir in Rio Blanco County, Colorado about 20 miles southeast of the town of Meeker. It also lies west of the unincorporated community of Buford. The reservoir is owned by Colorado Parks and Wildlife, and its dam impounds Big Beaver Creek, a tributary of the White River. Lake Avery is also called Big Beaver Reservoir, however it is unclear whether the name has changed or whether the reservoir just has two names.
