Lake Corpus Christi storage in context

Lake Corpus Christi water level, past 12 months

87.6% full at the latest reading - across the past 12 months it ranged from 8.3% (April 17, 2026) to 92.0% (August 17, 2026). Percent full is storage against the 256,062-acre-foot capacity basis, not a share of the elevation plotted above.

Lake Corpus Christi elevation, full record

87.6% full at the latest reading - across the storage record since September 1, 1948 it ranged from 5.8% (May 5, 1951) to 100.4% (October 25, 2007). Percent full is storage against the 256,062-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.
