From Colorado Trout Unlimited via The Sky-Hi Daily News:
A project designed to improve the Fraser River in Granby began construction Thursday.
Construction is expected to be completed by the end of November and the bridge across the Fraser River at Kaibab Park will be closed during the work.
The Granby Diversion Dam, which helps divert the town’s water supply and agricultural irrigation water, is an 80 foot wide, 3.5 foot high boulder structure that spans the Fraser River. At low flows, the dam is a barrier that prevents fish movement critical for a healthy fishery and blocks the movement of small non-motorized crafts that currently portage around it, according to a release from Trout Unlimited.
The project is the result of a partnership between Granby, Trout Unlimited and Grand County. Funds were contributed by the US Fish and Wildlife Service, the Colorado Water Conservation Board, and the Open Lands, Rivers and Trails Fund, with the Northern Colorado Water Conservation Board contributing most of the materials for the project and Colorado Parks and Wildlife providing assistance.
The goal of the project is to provide fish passage for trout and native species and for non-motorized boating recreation without interfering with water diversion for municipal and irrigation purposes. The project will also provide resilience for future flood events, facilitate natural stream processes like sediment transport and no rise in the 100 year floodplain.
