A Southeast Colorado river is going dry — and your water plan may have the same problem

A report this week from Colorado Public Radio described a drought-stricken river in Southeastern Colorado losing its flow — in August, when snowmelt is long gone and the region depends on whatever water remains in the system. This is not a distant hydrological abstraction. It is a visible signal of what CDSS (Colorado Division of Water Resources) call "call conditions," where senior water rights holders pull so hard on a shrinking system that junior users — including some municipal suppliers — get cut off entirely.

What is actually changing

The Arkansas River basin and the smaller drainages feeding Southeastern Colorado have been under compounding stress. The 2021-2023 drought years drew down reservoirs and aquifers. The 2025-2026 snowpack came in below average in the southern mountains. When a river visibly stops running in midsummer, it means every buffer in that system — reservoir storage, alluvial groundwater, return flows from irrigation — has already been spent.

The household risk is not that your tap goes dry tomorrow. It is that the infrastructure your water comes from is operating with less margin than it was five years ago. Smaller rural water districts in Pueblo, Huerfano, Bent, and Otero counties often have a single source and limited storage. If that source is stressed, so is the district. Well owners in those counties face a different problem: wells screened into shallow alluvial aquifers connected to a river that is not running can lose yield within weeks of a river going dry.

The Front Range is not insulated. Denver Water and Aurora Water both hold senior rights and significant reservoir capacity, but they are not untouched. Colorado Springs Utilities draws from both the Pikes Peak watershed and transbasin diversions that run through stressed southern drainages. The more other users draw in a call year, the more carefully managed every diversion becomes.

This is also not the last summer like this. Recent NOAA climate projections for the Southwest consistently show longer dry seasons and higher evaporative demand across the Colorado high plains. Each of these summers tests the system a little harder.

What we would actually do

Find out specifically where your water comes from. Call your water provider and ask: what is your primary source, and do you have secondary supply? Most utilities will tell you. If you are on a private well, have a licensed driller pull the well log from the Colorado Well Permit Database (online, free) and check the screened depth and aquifer type.

If your provider cannot tell you their backup source, that is itself useful information — it means there may not be one. Knowing this does not require you to panic; it requires you to plan around a realistic possibility.

Store two weeks of drinking water per person at home. FEMA guidance is 72 hours. That was written for acute emergencies, not for a slow-moving infrastructure stress event that might require conservation orders for weeks. At one gallon per person per day for drinking and basic hygiene, a family of four needs 56 gallons. Six stackable seven-gallon WaterBrick containers, filled from the tap and rotated annually, solve this for under $120.

Audit your irrigation and outdoor water use now. If your municipality is drawing from a stressed source and issues Stage 2 or Stage 3 restrictions, lawn watering is the first thing cut. That matters for finances (landscaping replacement is expensive) and for garden food production (if you grow any). Drip irrigation and mulching are the most cost-effective response — not a second tank or a cistern, which are expensive and regulated in Colorado.

Check whether your county has a drought contingency plan. Many Colorado counties and water districts publish these online. If yours does, read the trigger thresholds. Stage 1 typically means voluntary cuts. Stage 2 means mandatory outdoor restrictions. Stage 3 means commercial and some indoor use gets restricted. Knowing where your district sits on that ladder in real time is more useful than any amount of general preparedness reading.

Talk to your neighbors who run wells. If you are in Southeastern Colorado and you know someone with an agricultural well, ask whether their yield has changed this summer. Informal well-yield reports from neighbors are often the earliest possible signal that an aquifer is thinning, well ahead of any official notice.

The bigger picture

A river going dry in August is a systems signal, not a catastrophe announcement. Colorado's water law is the most elaborately managed prior-appropriation system in the country, designed precisely to allocate scarcity. It will continue to function under stress. What changes is how much margin households and small districts have for error.

Durability here does not mean drilling a private well or buying a truck-mounted cistern. It means understanding your actual supply chain, storing a realistic buffer, and removing unnecessary demand before restrictions force you to. The households that manage drought seasons well are not the ones with the most gear. They are the ones who knew their system well enough to see the stress coming and adjusted before it became a crisis.
