Water-right lineage
This timeline puts WDID 0600565’s decreed rights (Leyner Cottonwood Ditch) — the same rights as the portfolio above — in chronological order by appropriation date (oldest first), grouped by decade. It reflects DWR’s current net-amounts tabulation, not a complete decree history: intermediate decrees, changes, and abandonment proceedings exist only in the underlying court case files. It is not a title opinion and not a complete chain of title.
18 additional rights recorded only as alternate-point/exchange (APEX) net amounts are not included in this timeline. 1 right shown also carries APEX amounts that are not displayed.

The parcels are mapped by the State of Colorado, not by the company and not by DitchBook. The state's mapping for this company includes parcels the state also links to a groundwater (well) supply; parcels the state maps to this company's structures together with other structures; parcels the state maps to this company's structures alone. Where parcels are shared with other structures or linked to a well, the acres shown are not all served by this company's ditch alone. How this page is built.

DitchBook is not affiliated with Leyner-Cottonwood Consolidated Ditch Co. This page is a public-record profile compiled from Colorado Secretary of State and public water-district data.
A mutual ditch or reservoir company is a nonprofit corporation formed under Colorado law — most commonly C.R.S. Title 7, Article 42 — so that landowners who share an irrigation ditch, canal, or reservoir can jointly own and operate it. Instead of the water right belonging to a single person, shares in the company represent each owner's proportional claim, and the company's board and secretary keep the ledger, run assessments for maintenance, and issue certificates the way any small corporation would. Many of these companies have operated continuously since the 1880s, run entirely by volunteer officers who inherit the books from whoever kept them before.
Buying or selling land with shares in Leyner-Cottonwood Consolidated Ditch Co.?
Ditch shares are corporate stock — they don't transfer with the deed, and under C.R.S. § 7-42-104 unpaid assessments follow the shares to the new owner as a lien. The plain-English walkthrough — including what the standard Colorado contract does and doesn't protect — is at Ditch shares at closing on Water Rights Colorado, a guide site from DitchBook's operator.
