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 ↗Upper Rio Grande Basin governed by the 2021 Rules Governing Withdrawal of Groundwater in Division 3 and the Rio Grande Water Conservation District subdistricts (No. 1-6 + Trinchera). Confined and unconfined aquifers are over-appropriated; new consumptive appropriations are effectively unavailable, wells must replace injurious depletions, and subdistricts impose pumping curtailment/fees with State-Engineer curtailment for unresolved depletions.
Colorado DWR — Designated Basins / Division 3 ↗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.
