Lake Crook elevation, full record

87.8% full at the latest reading - across the storage record since March 26, 1999 it ranged from 63.8% (December 8, 1999) to 100.0% (July 14, 2026). Percent full is storage against the 9,195-acre-foot capacity basis, not a share of the elevation plotted above. Every percentage here is measured against today's capacity basis; a reservoir's surveyed capacity changes as sediment accumulates behind the dam, so early-record percentages are indicative rather than exact.
