The Connectivity Channel Project will move the reservoir’s existing southern embankment 300 yards, reducing the reservoir’s surface area by about 30%, allowing for a new channel and floodplain. This will reconnect the river upstream of the dam and downstream at the confluence of the Colorado and Fraser Rivers. Construction will be completed in the fall of 2024.
During the groundbreaking ceremony, individuals spearheading the project spoke to a crowd gathered beside the reservoir’s soon-to-be-realized channel. The speakers represented an unprecedented collaboration between diverse groups across Colorado, including: Grand County government, state entities, Trout Unlimited, Colorado Parks and Wildlife, Colorado Water Conservation Board, Colorado River District and many more. Northern Water’s Municipal Subdistrict leads the project. Brad Wind, Northern Water’s General Manger, told the crowd the project will improve “all the ecology that make high mountain streams important to the environment and to Colorado.”
Reconnecting the Colorado will allow for the free passage of fish and sediment, plus create around 50 acres of floodplain and riparian habitat, restoring stream health. The channel will provide over 1 additional mile of public fishing access for the Gold Medal trout fishery, an important benefit for Grand’s recreation industry. Lastly, the project will support additional restoration efforts, such as improving irrigation and aquatic habitat near Kremmling…
An essential facet of the Connectivity Project is its relation to the Windy Gap Firming Project. Shortly after Windy Gap’s construction, Northern Water realized this was an inefficient means for them to draw water from the Colorado River. Their rights are for 30,000 acre-feet annually. But during wet years, Lake Granby was too full to take this water for delivery to the Front Range, so it sat in Windy Gap. Other years, especially during recent drought, Lake Granby was too low for Northern to pump the water they needed. On top of this, the Front Range population was increasing. Northern Water began creating a better storage option…Northern began construction on the Chimney Hollow Reservoir west of Loveland to ensure the reliability of, or make “firm,” its deliveries of Windy Gap water, even during drought. Instead of being stored in Lake Granby, water from Windy Gap will travel through Lake Granby, then over the Continental Divide, to be stored at Chimney Hollow instead.
