Deepest lakes & reservoirs in Washington by maximum depth (ft)
The estimated greatest depth of the water in a lake can be measured at the lake’s normal elevation. If the water volume and surface area of a lake are known, an estimate of the lake’s average depth can be calculated:Water volume ÷ Surface Area = Average Depth
Example: 1,000,000 acre-feet ÷ 20,000 acres = 50 feet average depth.
