Red Bluff Reservoir elevation, full record

46.3% full at the latest reading - across the storage record since February 1, 1937 it ranged from 7.5% (May 14, 1937) to 104.1% (October 3, 2014). Percent full is storage against the 145,165-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.
