Greenbelt Lake storage in context

Greenbelt Lake water level, past 12 months

4.8% full at the latest reading - across the past 12 months it ranged from 4.8% (September 8, 2026) to 9.0% (September 8, 2025). Percent full is storage against the 59,968-acre-foot capacity basis, not a share of the elevation plotted above.

Greenbelt Lake elevation, full record

4.8% full at the latest reading - across the storage record since August 17, 1967 it ranged from 4.2% (August 30, 1967) to 73.7% (June 28, 1975). Percent full is storage against the 59,968-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.

Update cadence

Daily

TWDB reports conservation storage against a conservation capacity that is restated as new volumetric surveys are completed, so a percent-full figure here can change without the water level changing. TWDB's methodology page is linked in the notes below.
