Lake Brownwood storage in context

Lake Brownwood water level, past 12 months

85.1% full at the latest reading - across the past 12 months it ranged from 81.2% (May 18, 2026) to 93.0% (July 21, 2026). Percent full is storage against the 130,868-acre-foot capacity basis, not a share of the elevation plotted above.

Lake Brownwood elevation, full record

85.1% full at the latest reading - across the storage record since July 1, 1933 it ranged from 0.0% (April 1, 1935) to 100.0% (July 20, 2025). Percent full is storage against the 130,868-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.
