Proctor Lake storage in context

Proctor Lake water level, past 12 months

64.9% full at the latest reading - across the past 12 months it ranged from 64.9% (September 8, 2026) to 90.7% (September 8, 2025). Percent full is storage against the 54,762-acre-foot capacity basis, not a share of the elevation plotted above.

Proctor Lake elevation, full record

64.9% full at the latest reading - across the storage record since February 2, 1963 it ranged from 0.4% (May 21, 1963) to 101.3% (January 31, 2012). Percent full is storage against the 54,762-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.
