Shoshone hydropower water right ‘relaxed’ in collaborative response to 2-year drought; agreement enables about 20,000 acre feet of additional upstream storage early in the year

FRISCO — Some key players in the Colorado River Basin have worked together to “relax” a senior water right near Glenwood Springs, enabling more water — about 20,000 acre feet — to be stored in upstream reservoirs.
“We expect to gain about 8,000 acre-feet each in Dillon and Williams Fork Reservoirs as a result of the relaxation,” said Denver Water spokesperson Stacy Chesney.
The 1,250-cfs water right for the Xcel-owned Shoshone hydropower plant dates back to 1902, making it one of the most senior rights on the river.
When Xcel exercises that water right, it affects other water users all the way up the river because it’s administered by the Colorado Division of Water Resources against junior water storage rights in Dillon and Williams Fork Reservoirs, the Colorado River District’s Wolford Mountain Reservoir and the Bureau of Reclamation’s Green Mountain Reservoir.
