Professional tool · Statewide public water screen

Ditch Finder

Start with a property, not a company name. Build a parcel-specific evidence packet with reviewed ditch geometry, verified WDID and company sources, official mapped surface water, explicit search status, and a closing verification order.

Include the city and state for the most reliable match.

Your browser sends the address to the Census geocoder, the resulting coordinate to Colorado's parcel service, and the selected parcel envelope to USGS. Screening stays in your browser. For Weld County only, DitchBook receives and stores the matched address and displayed evidence if you choose Investigate this parcel.

Statewide: parcel boundary + public surface-water screen, with mapped DitchBook structures for companies. Limits

Parcel numbers are digits only; Weld account numbers may also start with R (R4281886). Spaces and dashes are ignored. If the number repeats between counties, you will choose the right public record.

Your browser asks Colorado's parcel service for that public record, then asks USGS for mapped hydrography around its envelope. Screening stays in your browser. The private investigation handoff is available only for Weld County.

These point distances are useful for general research. In a completed parcel screen, they are not parcel-to-company evidence.

Coverage and limitations

Type an address and this tool asks the U.S. Census Bureau's public geocoder to turn it into a latitude and longitude. The browser asks Colorado's public parcel service which polygon contains that coordinate, then checks DitchBook-reviewed alignments and official USGS 3DHP flowlines and waterbodies at or within one-half mile of that polygon. It also returns the nearest 15 company-linked structures within 25 miles as optional regional context.

Three different kinds of evidence

Verified irrigation evidence means a DitchBook-reviewed alignment is connected to published WDID and company sources. Public hydrography means the official USGS map shows a channel, drainageway, general canal, river area, canal area, or Lake-class waterbody; it does not identify a company or water right. Secretary verification required covers private company records such as shares, assessments, account status, and transfer requirements. The tool never turns one kind into another.

What "verified and published" means

A structure only appears here if DitchBook has matched it to a specific ditch or reservoir company at the tier-1 standard described on the methods page — the state's own DWR record has to name that company, never a fuzzy guess — and it has a defensible mapped point. Most points are DWR's own latitude/longitude. If DWR's coordinate is blank for an exact-name reservoir, DitchBook may use a clearly labeled approximate interior point from the official USGS NHD waterbody polygon; that is not a surveyed dam, outlet, or legal diversion point. As of this build, that's of published structures, representing of the matched companies; the remainder can't be placed or ranked honestly even though the company match itself is real.

What a missing result means — and doesn't

Colorado has far more ditches and reservoirs than DitchBook has verified so far. If nothing turns up near an address, that's a statement about DitchBook's coverage, not about the property — it does not mean no ditch or water right exists nearby. See buying land with a ditch for what to actually check before a purchase or closing: a title search and the county's own records, not this tool.

Straight-line distance, not ditch distance

The distance shown is the straight-line (great-circle) distance between the address and the structure's mapped point — not the distance along the ditch itself, a road, or a property boundary, and not a statement about which parcels the ditch actually serves. Two properties the same straight-line distance from a headgate can have very different relationships to it.

Screening stays in your browser

The address goes directly from your browser to the Census Bureau's geocoder. The resulting coordinate goes directly to Colorado's public parcel service, and the selected parcel envelope goes directly to the USGS hydrography service. DitchBook does not receive or store those screening requests. For Weld County only, choosing Investigate this parcel first discloses what will be stored, then sends the matched address, displayed parcel geometry, and evidence summary to DitchBook's private workbench. A verification request opens your own email app and sends nothing unless you choose to send it.
