How We Calculate These Numbers

Daily history for Table Rock Lake uses one USACE CWMS hourly elevation per local day. 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 Table Rock Lake uses 11 readings on this calendar day from 2015 through 2025 and equals 913.82 ft. All of these figures come from USACE CWMS time series SWL:Table_Rock_Dam-Headwater.Elev.Inst.1Hour.0.Decodes-rev. Percent full is shown only when an agency published it; it is never estimated by dividing elevation by a pool elevation.
