How We Calculate These Numbers

Daily history for Shasta Lake uses the Bureau of Reclamation's daily elevation values from RISE. This page doesn't show a full-pool line because the fetched sources didn't confirm one on this datum. The same-day mean at Shasta Lake uses 11 readings on this calendar day from 2015 through 2025 and equals 973.47 ft. All of these figures come from station 10863. Percent full is shown only when an agency published it; it is never estimated by dividing elevation by a pool elevation.
