From The Summit Daily (Sawyer D’Argonne):

The Federal Emergency Management Agency awarded a $10 million grant to the state of Colorado last week to help fund modifications to the Goose Pasture Tarn Dam.

The funds come as part of FEMA’s Pre-Disaster Mitigation Grant Program, which is meant to help minimize the risks of possible dam failures…

The dam — south of Breckenridge proper and north of Blue River — is classified as “high hazard” by the state, a categorization that has little to do with its condition but rather the potential loss of human life and property in the event of any type of failure. According to FEMA, a failure likely would impact more than 2,000 residences and businesses in the Breckenridge area below the dam, along with major damage to roadways and the community’s existing water supply.

The dam does need some work to help put the minds of Breckenridge residents at ease. The need for upgrades began to emerge in 2015, during a high moisture year when town-run monitoring stations started to see significant rising water levels, according to Steve Boand, a state hazard mitigation officer with the Colorado Division of Homeland Security and Emergency Management. As a result, stakeholders decided to implement reservoir storage restrictions in 2016.

Breckenridge also moved forward in seeking federal funding to address concerns. The $10 million from FEMA will cover more than half the costs of the project. The rest already has been budgeted as capital improvements by Breckenridge, Boand said. The work on the dam is scheduled to begin later this year and will lower the spillway by 4 feet to help protect the dam and everyone in its path…

Construction on the project will begin later this year and is scheduled to be completed sometime in 2022, though Boand said it could take until 2023. Breckenridge will lower water levels in the reservoir during construction seasons to facilitate the work.
