As of 2026-07-27, DWR Water Rights Net Amounts. Absolute rights are decreed for water already put to use; conditional rights hold a place in line for use not yet completed. Amounts are shown exactly as the state records them. How this page is built.

Water-right lineage

This timeline puts this company’s decreed rights across all 23 structures listed above in chronological order by appropriation date (oldest first), grouped by decade; each entry names the structure (WDID) it belongs to. 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.

117 additional rights recorded only as alternate-point/exchange (APEX) net amounts are not included in this timeline. 4 rights shown also carry APEX amounts that are not displayed.

Annual values follow the DWR water year (November–October). Structure records begin and end in different years; DitchBook does not sum diversions across structures. — means DWR has no annual-total row for that structure and year; it is not zero. Years marked provisional are DWR's own provisional records — the state has not finalized them, and they are drawn with a dashed outline above. All other years are published records. Water year 2026 is partial and will change as DWR records are updated. A diversion record is what the state's records show ran through the headgate; it is not a share, an entitlement, or a company allocation. How this page is built.

9 of 23 structures have no DWR annual-total diversion class: 0500647, 0500649, 0500671, 0500672, 0500673, 0500968, 0504012, 0504015, 0504077.

Public notice activity

    This dated notice is evidence that a replacement demand was published, not proof of current ownership, share validity or value, transfer completion, or the company's present status.

DitchBook publishes only human-reviewed notice events with a source date, page or record locator, URL, document hash, and explicit limitation. Discovery hits that are fuzzy, ambiguous, or privacy-sensitive stay out of public company pages. Coverage and methods.

DitchBook is not affiliated with Left Hand Ditch Company. 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 Left Hand Ditch Company?

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.
