During cold weather, ice effects on stage and discharge determinations
at some stream-gaging stations are likely. Data values reported on
these pages may be significantly higher or lower than actual
streamflow. Adjustment of data for ice effects can only be done after
detailed analysis. Users are encouraged to contact this office for more
information on specific stream-gaging stations.

REMARKS.--
| The 1-hour precipitation data for this station are temporary and will only be displayed for 60 days. Time series of 1-hour or cumulative daily values will NOT be available for retrieval following the 60-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. |
COOPERATION.--Funding for the operation of this station is provided by the U.S. Army Corps of Engineers, the Pennsylvania Department of Environmental Protection, and the U.S. Geological Survey.
