Chimney Hollow Reservoir is finally filling with water—and that’s big news for Colorado’s future.
After more than 20 years of planning, construction, and public input, this long-awaited project near Carter Lake is coming to life. The reservoir, which will store up to 90,000 acre-feet of water, represents one of the largest new water supply investments on the Northern Front Range in decades.
Why Chimney Hollow Matters for Colorado Homeowners
If you live in Loveland, Longmont, Broomfield, or other growing communities along the Front Range, this reservoir could directly impact your long-term water security.
✅ More drought resilience in dry years
✅ Better supply planning for growth and demand
✅ Reduced pressure on groundwater and aging reservoirs
In recent years, Colorado has faced increasing strain on both surface water and underground aquifers. Chimney Hollow helps balance that equation by offering a fresh, sustainable source tied to the Colorado-Big Thompson Project.
“This is one of the most important water projects of the past 50 years,” said Jeff Drager of Northern Water. “It provides flexibility and stability for our communities.”
Where Is Chimney Hollow Reservoir?
Chimney Hollow is located just west of Carter Lake, nestled in the foothills of Larimer County. Water will flow into the reservoir from the Colorado River headwaters, through existing infrastructure, helping manage storage more efficiently.
It’s not just a reservoir—it’s a tool for smarter water use.
What Homeowners Can Do Today
While Chimney Hollow brings long-term benefits, it doesn’t change the fact that Colorado homeowners still need to manage water wisely today. Here’s how you can stay ahead:
Get a water quality test to understand what’s in your water (especially if you’re on a private well)
Install water-efficient systems like softeners or reverse osmosis filters
Consider rentals if you’re not ready for a full system—Aqua Serve offers flexible options
