Shasta Lake storage in context

Shasta Lake water level, past 12 months

51.2% full at the latest reading - across the past 12 months it ranged from 51.2% (October 21, 2026) to 91.4% (May 5, 2026). Percent full is storage against the 4,552,000-acre-foot capacity basis, not a share of the elevation plotted above.

Shasta Lake elevation, full record

51.2% full at the latest reading - across the storage record since January 1, 1985 it ranged from 0.5% (April 29, 1987) to 99.7% (April 30, 2003). Percent full is storage against the 4,552,000-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.
