Water for the Lake Powell Pipeline (LPP) is supplied from an existing right to divert water from the Green River, a tributary of the Colorado River.
Utah’s use of the water is planned for within the state’s Colorado River appropriation. LPP planning incorporates the impacts of climate change, extended drought and reduced natural flows in the Colorado River. The LPP will be used within the limit of Utah’s allocated Colorado River supply.
Additional information on the Colorado River and Utah’s appropriation is available on The Colorado River Fact Sheet and the Colorado River Authority of Utah’s website.
