Lake Mineral Wells elevation, full record

86.8% full at the latest reading - across the storage record since February 19, 1999 it ranged from 61.4% (October 22, 2023) to 128.2% (August 5, 2015). Percent full is storage against the 5,273-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.
