Lake Houston is a water-supply lake, run by the City of Houston. It is normally held near a steady level, rising after heavy rain and falling in dry spells.
Elevation is the height of the lake surface above the gauge's reference level, not a water depth. Storage is USGS's estimate of the water held, in acre-feet (one acre-foot covers an acre a foot deep).
