Who owns the water
In Colorado water is a property right, ordered by who claimed it first. The state engineer's office keeps that ledger and shuts off junior users in a dry year.

Colorado water, statewide and where you live
Snowmelt, rivers, reservoirs, canals, treatment plants, and dozens of public bodies stand between a storm on the Divide and your kitchen sink. Type your town below, or pick a basin on the map, and the page recenters on your patch of the state.

Step 1 · Your place
Colorado divides water planning into nine regions, and their edges follow the divides between river systems, not county lines. Pick one, search your town, or stay statewide.

All nine regions
Statewide bodies set the frame every region works inside: the water plan, the grant programs, the permits, and the stream gauges that everyone else's numbers come from.

In ColoradoStep 2 · The short version
Two minutes on the shape of it. Some of these bodies govern everywhere in Colorado; some are specific to Colorado.

In charge here: Colorado Division of Water Resources
Every region writes its own plan for supply gaps, healthy rivers and agriculture, then feeds it into the statewide Colorado Water Plan.
In charge here: The state's nine basin roundtables
Most local projects run on state grants and a handful of statewide funds, matched with local money. Those programs publish their deadlines and their grantees.
In charge here: Colorado Water Conservation Board grant programs
Watershed groups, districts, utilities and volunteers restore streams, monitor quality, fix headgates and run the education that keeps it going.

Step 3 · Your move
Every one of these is a public door: a meeting you can sit in, a newsletter you can read, a group that wants volunteers, a person who answers email.
