Prior to Apr. 14, 1940, non-recording gage and Apr. 15, 1940 to Oct. 22, 1990, water-stage recorder at same site at datum 0.75 ft higher. Satellite telemetry at station.
COOPERATION.--Station established and maintained by the U.S. Geological Survey. Funding for the operation of this station is provided by the Pennsylvania Department of Environmental Protection, the U.S. Army Corps of Engineers, Pittsburgh District and the U.S. Geological Survey through the National Streamflow Information Program and the Cooperative Water Program.
REMARKS.--Sharp rises and drops in gage height displayed on graphs for some of the Allegheny River gages are caused by hydroelectric power producers passing relatively large amounts of streamflow. ,/table>
Supplied by NWS:Action stage-17.2 ft; Flood stage-21 ft; Moderate flood stage-24 ft; Major flood stage-26 ft.
The 15-minute precipitation data for this station are temporary and will only be displayed for 120 days. Time series of 1-hour or cumulative daily values will NOT be available for retrieval following the 120-day display period. Although the instrumentation is calibrated at least once a year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
This station managed by the PAWSC Pittsburgh Field Office.
