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	LUPTON LAKES RESERVOIR COMPLEX: 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
77	Critical call exposure	LUPTON LAKES RESERVOIR COMPLEX (2007 priority) carries 3,998.8 day-equivalents of observed call exposure from 91 senior caller(s); dominant caller SOUTH PLATTE RIVER COMPACT (573.1 day-eq). 3212 season-days curtailed in the last five seasons.	100.0
70	Season call nowcast: expected curtailment	LUPTON LAKES RESERVOIR COMPLEX, 2026 season outlook: Apr 1 SWE 61% of median → severe-class year; expected curtailment ~212 of 214 season days from the basin's administration record. Dominant caller SOUTH PLATTE RIVER COMPACT: P(call by Jun 15) = 1 over 6 comparable seasons.	100.0
