Lake Mead's Water Level, 1935–2026

About this chart
The glass sphere is Lake Mead, and the liquid in it is how much it holds: the share of the sphere's circle that is filled is the share of the lake's capacity held, so half full sits at the middle and the surface moves fastest near empty and near full. A dashed line marks 1,035 feet, the level below which most of Hoover Dam's turbines cannot run, and a scale mark that would sit on it is not drawn. While the level is below it, the liquid is drawn red. Scale marks stand beside the glass at a quarter, a half and three quarters. The readout carries the month, the water level in feet and the share. The animation runs the record over fifty-six seconds, holds on the last month for three seconds, and loops. The scrubber under the chart marks every year and labels the decades (every fifth year on a short record), and pauses on any month; the speed can be changed in the controls.
Method
The level is Lake Mead's water surface at Hoover Dam, in feet above sea level, as the Bureau of Reclamation records it, on the last day of every month from February 1935, when its record begins as the lake started to fill, to the latest day Reclamation reports. The amount held is the water above 895 feet, the lowest level from which the dam can release water, read for each month's elevation from Reclamation's 2009 area and capacity tables for the lake; the sphere is full at 26,120,000 acre-feet, the capacity those tables give at 1,219.64 feet, above which the lake's space is kept for floods. Reclamation's own daily storage figures for the early decades were computed on older surveys of the lake and do not agree with the current tables at the same elevation, so every month here is measured on one table, the current one. In four months, July 1941 and June to August 1983, the lake stood above 1,219.64 feet: the sphere is drawn full and the readout gives the true share, above 100%. The dashed line is 1,035 feet. Reclamation's analysis for the guidelines that follow 2026 says that at that level Hoover Dam can use only its five wide-head turbines, because its twelve older turbines would suffer excessive damage; while the level is below the line, the water is drawn red. The lake first rose above it in April 1937. Two lower levels are not drawn: 950 feet, below which the dam cannot generate power, and 895 feet, below which no water can be released. The sphere fills by the area of its circle, so half full sits at the middle. Every figure on the page is computed from the rows the page serves.

Data table
Lake Mead's elevation at Hoover Dam on the last day of every month from February 1935, and on the latest day Reclamation reports, from its RISE daily record; the amount held is the available capacity above 895 feet that Reclamation's 2009 area and capacity tables give for that elevation, and the share is that amount over 26,120,000 acre-feet. These are the rows the chart draws. Public domain, U.S. Bureau of Reclamation.
