The Anstey River is a 30adj=midNaNadj=mid river in the Interior region of British Columbia, Canada. It flows roughly north to south from the Monashee range of the Columbia Mountains, and drains into Anstey Arm on Shuswap Lake.[1] The Anstey River drainage covers 24000ha and is uninhabited.[2] The river was named for Francis Senior Anstey, who operated one of the first major logging operations in the area. The lower river and its delta are protected within Anstey Hunakwa Provincial Park.[3]
