Flood Chart
National Weather Service flood stage for this
gage is 21.0 ft.
Forecasts for this gage are issued by the National Weather Service
routinely year-round.
Forecast information is available here.
The air temperature data for this station
are temporary and will only be displayed for 120 days. Although the
instrumentation is calibrated at least once/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.
