March 7, 2025 — The Colorado State Engineer officially designated the White River Basin above the Taylor Draw Power Conduit at Taylor Draw Reservoir, in northwest Colorado, as over-appropriated. A stream system is considered over-appropriated when at some or all times of the year, there isn’t enough water available to satisfy all the water rights within the system. The change will be effective May 1, 2025.
Water rights owners in the White River, which is part of the Colorado River basin and flows through Division 6 (Yampa, White, Green, and North Platte River Basins), have expressed in multiple years that they were not receiving their decreed amount and requested that the Colorado Division of Water Resources (DWR) staff to curtail water usage, which is known as a “call.” In December 2022, there was a call on the White River upstream of Taylor Draw Power Conduit, and another in July 2023. These events led Erin Light, DWR Division 6 Engineer, along with her team, to evaluate the situation and formally recommend that the Colorado State Engineer and Director of the Colorado Division of Water Resources designate the basin as over-appropriated.
“Calls in the past few years have made it clear to me that the White River does not supply enough water to meet demands during part of the year, leading me to request this designation that will protect senior appropriators from future unreplaced well depletions," said Light.
This designation means new, non-exempt well permits above the Taylor Draw Power Conduit will require an augmentation plan. An augmentation plan is a court-approved plan that would allow the water user to pump groundwater by replacing that water with an equivalent amount from another source.
“This designation is part of the unfortunate story we’re seeing play out across the Upper Colorado River Basin,” said Jason Ullmann, Colorado State Engineer and Director of the Colorado Division of Water Resources. “Extended drought and hotter temperatures, made worse by climate change, means there’s less water to go around. Even very senior water rights holders aren’t getting their full supply. Designating the White River as over-appropriated will help ensure senior water rights are protected and not harmed by additional groundwater pumping, which can impact surface water supplies.”
As the basin continues to develop, future water rights holders will develop water with an understanding that those rights will be administered in many or most years, depending on hydrology.
