ORDWAY, Colo. โ Grizzly Reservoir in Pitkin County will be drained for dam-maintenance construction after peak runoff and will be unavailable for public recreation this year. The Portal Campground and dispersed camping along Lincoln Creek Road will remain open.
Draining is expected to begin in mid-to-late June, with work completion estimated for late October, followed by refilling in accordance with the State-approved refill plan. The reservoir is expected to be available for public recreation in the 2027 summer season.
Grizzly Reservoir is owned and operated by the Twin Lakes Reservoir and Canal Company as part of the Independence Pass Transmountain Diversion System. This yearโs work is a continuation of the dam maintenance work started in 2024. Activities include construction of new dam outlet gates and completion of the waterproof liner to protect the steel face of the dam.
Construction traffic is expected on Lincoln Creek Road for the duration of the project and motorists travelling the road are advised to follow construction/traffic signage.
Based on lessons learned during the reservoir draining in 2024, the Twin Lakes Company has developed additional mitigation measures to reduce the likelihood, duration, and extent of any sediment discharges into Lincoln Creek and the Roaring Fork River during this yearโs reservoir draining. Some sediment discharge and discoloration of the water in Lincoln Creek and further downstream is still possible. Any such events will be promptly communicated to Pitkin County, Roaring Fork Conservancy, Colorado Parks & Wildlife, the U.S. Forest Service, and the U.S. Army Corps of Engineers.
