Gross Reservoir Expansion Project
Experts discuss how the Gross Reservoir Expansion Project will have a net environmental benefit on water quality in Colorado.

Provide $2 million towards aquatic habitat improvements on the Upper Colorado River.
Provide $1 million to the Upper Colorado River Wild and Scenic Management group to fund flow-related projects to protect the outstanding and remarkable values within segments of the Upper Colorado River.
Provide $6 million to Grand County to use towards environmental projects, and continue to participate in the “Learning By Doing” collaborative effort, which has already resulted in tangible positive environmental impacts on the West Slope.
Release water into Ranch Creek in response to high temperatures found through water temperature monitoring. Check out, “Searching for solutions to help trout keep their cool.”
