Twin Lakes Diversion (Roaring Fork River)

The Independence Pass Transmountain Diversion System (Twin Lakes) collects water from a 45 square mile area of the Upper Roaring Fork River subbasin. The Twin Lakes Diversion moves water from the Roaring Fork River, Lost Man Creek, Lincoln Creek, Brooklyn Creek, Tabor Creek, New York Creek and Grizzly Creek through the Twin Lakes Tunnel to Twin Lakes Reservoir, in the Arkansas River watershed. The project currently diverts 38,000 acre feet of water but has water rights to divert as much as 46,000 acre feet, annually.

Twin Lakes Diversion System is owned and operated by Twin Lakes Reservoir and Canal Company in Ordway, Colorado.
