Water Data for the Nation inventory

Monitoring location 01118500 is associated with a Stream in Washington County, Rhode Island. Current conditions of Discharge and Gage height are available. Water data back to 1927 are available online.

The elevation of this station has been determined to be 0.0 ft above NAVD 1988. To obtain stream water surface elevation values in NAVD 1988 add 0.0 ft from gage height values. Prior to October 1, 2023, the elevation of this station has been determined to be 4.6 ft below NAVD 1988. To obtain stream water surface elevation values in NAVD 1988 subtract 4.6 ft from gage height values.
