The conservancy is a relatively undisturbed watershed adjacent to Lillooet Lake and falls within the Lil’wat Nation Traditional Territory (Lil’wat Territory).
The conservancy is 2,095 hectares in size and is comprised of the entire Twin Two watershed, which flows into the eastern shore of Lillooet Lake, called Lil’wata Tselalh in Ucwalmicwts (the Lil’wat Nation language).
The conservancy contains six hectares of foreshore along Lillooet Lake and extends from the foreshore to high alpine lakes at the divide to the Van Horlick Creek drainage to the east. The western boundary of the Stein Valley Nlaka’pamux Heritage Park is approximately four kilometres from the upper alpine boundary of the conservancy.
Joffre Lakes Park and the Nlháxten/Cerise Creek Conservancy are located to the northeast and the Upper Rogers kóḻii7 Conservancy is located to the south.
