In Elbert County, the water under your feet is the Denver Basin

Elbert County does not sit on a big river, and most of it is not on a city water line. A large share of its water comes from underground, out of the Denver Basin.

The Denver Basin is a stack of bedrock aquifers, layered formations with names like Dawson, Denver, Arapahoe, and Laramie-Fox Hills. Wells reach down into these layers to bring up water for homes, ranches, and small towns across the county. Unlike a stream that refills with each snowmelt, deep bedrock water can recharge very slowly, so the state and the county keep an eye on how levels change over time.

That is why Elbert County has been studying its groundwater for years — work that led to the 2024 Elbert County Water Master Plan. As more people move onto rural lots, more wells draw from the same layered system.

Why this matters for a buyer or landowner: for many rural properties in Elbert County, “where does the water come from” means a well into the Denver Basin. Understanding which aquifer a property’s well taps, and how that water is permitted, is a core part of understanding the land here.

For how the Denver Basin aquifers work and how wells into them are permitted, start with the Colorado Division of Water Resources and the county’s groundwater study pages.
