Navajo Reservoir elevation, full record

46.9% full at the latest reading - across the storage record since July 1, 1962 it ranged from 0.2% (July 1, 1962) to 102.1% (July 3, 1973). Percent full is storage against the 1,696,000-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.
