The Boxelder Creek Watershed Dams B-2 and B-3 were originally constructed in the early 1980s to protect agricultural land in north central Colorado from flooding.
After 35 years of population growth and land development, these rural dams now protect highly developed areas of unincorporated Larimer County, Wellington, Timnath, and parts of eastern Fort Collins.
In July 2013, the Colorado Division of Water Resources/Dam Safety Branch raised the hazard classification of both dams from significant to high. The Boxelder B-2 and B-3 dams are now required to meet higher state and federal dam safety standards.
In May 2015, a watershed planning study was begun to evaluate alternatives for rehabilitating the dams to serve current needs and meet higher dam safety standards.
Please read the Boxelder Watershed Dams B-2 and B-3 Rehabilitation Purpose and Need Statement, the first document produced for this planning study, for a detailed analysis of project purpose and need.
