Lake Worth elevation, full record

67.1% full at the latest reading - across the storage record since October 2, 1981 it ranged from 51.3% (February 14, 2015) to 151.8% (April 30, 2001). Percent full is storage against the 24,419-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.
