  • Additional information:

    [!] 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 values. 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 sites.

The 1-hour 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.
