Whether a new home can legally get its own water here — the sub-state groundwater regime, from Colorado’s water agency.
The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.
A household obtains water via a permit-exempt small-capacity well (15 gpm) under CRS 37-92-602 outside designated basins or CRS 37-90-105 inside them; on a 35-acre-plus lot limited outside/stock/1-acre irrigation is allowed.
Limit: Household-use-only well: 15 gpm, ≤0.33 acre-ft/yr, indoor only. Domestic well on a 35+ acre tract: 15 gpm, ≤1 acre-ft/yr.
Colorado DWR — Guideline 2023-1, Exempt & Small-Capacity Wells ↗New large-capacity wells need a Colorado Ground Water Commission permit and are allocated on an allowable 100-year water-level decline; in over-allocated management districts new large-capacity permits are effectively unavailable. Household/exempt small-capacity wells still allowed.
Colorado DWR / Ground Water Commission — Designated Basins ↗Small NE-plains designated basin adjacent to the Northern High Plains basin; over-appropriated. County placement lower-confidence (DWR does not enumerate this basin's counties).
Colorado DWR — Designated Basins / Division 3 ↗New wells require a Ground Water Commission permit; new large-capacity alluvial appropriations limited by prior appropriation, while Denver Basin bedrock is allocated by overlying acreage on a 100-year aquifer life.
Colorado DWR — Designated Basins ↗Prior-appropriation state (first in time, first in right). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the Colorado state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
