Water Data for the Nation inventory

Monitoring location 08132000 is associated with a Lake, Reservoir, Impoundment in Tom Green County, Texas. Current conditions of Lake or reservoir water surface elevation above NAVD 1988 are available. Water data back to 1930 are available online.

Datum of gage has been determined to be 0.00 feet above NAVD 1988. To obtain reservoir water-surface elevations in NAVD 1988 add 0.00 feet to gage height values
