6 · What can impair it — active signalsevery detection on this structure, its rights, and its land

Pri	Signal	Detail	Score
79	Augmentation condition not verified	COFFIN DAVIS DITCH: the decree requires augmentation coverage for out-of-priority depletions, but NO plan membership is found. Verify coverage before relying on this supply — absent a plan, curtailment is immediate on the next call.	85.0
71	Critical call exposure	COFFIN DAVIS DITCH (1871 priority) carries 602.9 day-equivalents of observed call exposure from 14 senior caller(s); dominant caller JAMES DITCH (118.3 day-eq). 508 season-days curtailed in the last five seasons.	49.0
63	Season call nowcast: expected curtailment	COFFIN DAVIS DITCH, 2026 season outlook: Apr 1 SWE 61% of median → severe-class year; expected curtailment ~112 of 214 season days from the basin's administration record. Dominant caller JAMES DITCH: P(call by Jun 15) = 0.67 over 6 comparable seasons.	77.9

7 · Verify before closingthe transaction-specific evidence checklist

resolve right ownership: best evidence is probable — county deed research + company records required
confirm administration exposure: 6 observed senior caller(s); verify current call status with the division office
