Provisional data for Pennsylvania
ICE EFFECTS
ON STREAMFLOW -- During cold weather, stage and discharge values may be
affected by ice at some streamgages. Streamgages experiencing ice
conditions will have the discharge record temporarily disabled to
prevent the display of erroneous discharge values. Display of discharge
record will resume when it is determined that ice conditions are no
longer present. Adjustment of data affected by ice can only be done
after detailed analysis.
Provisional Data StatementData are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Real-time data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified. Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data. Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS. |
