Lesson E2 · Changing a Right · transfers & change cases
Who objects, and why
File to change a water right and within weeks you will meet your neighbors — as opposers. Not because they are hostile: because on a river where everyone lives on everyone else’s return flows, your change is potentially their injury, and a water court statement of opposition is how they hold a seat at the table while the engineering gets argued.
What an objection is actually about
Almost always: timing and pattern, not volume. The applicant swears the change takes no more than historical consumptive use; opposers test the period chosen, the return-flow accounting, the dry-up covenants. The result is typically a negotiated decree bristling with terms and conditions — and those cases repeat with the same cast, because the same ditches share the same reach for a century. A structure’s co-parties in past cases are a map of whose water is entangled with whose.
Who has shared a courtroom with AGRICULTURAL DITCH
Our decree graph finds 21 shared cases connecting this structure with 35 other structures:
- 05CW0114 (2005) — WELCH DITCH
- 03CW0351 (2003) — MAPLE GROVE RES
- 96CW0098 (1996) — WELCH DITCH
- CA50044 — 0700659
- CA51834 — LEES BAUGH DITCH
Sharing a case number means being in the same proceeding — applicant, opposer, or co-applicant; the record often does not say which. The full graph is on its dossier.

What this does not let you conclude
Shared case numbers show co-presence in proceedings, not positions taken or outcomes won — and omnibus proceedings sweep in whole districts, which the graph flags rather than counts as adversity. Advisory reading aid on public data — never an administrative or legal conclusion, and never a substitute for DWR administration or an engineer’s analysis. Our methodology has not yet had outside expert review: how this is built.
