USGS 03277200 OHIO RIVER AT MARKLAND DAM NEAR WARSAW, KY

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text
The unit-value precipitation data for this station are temporary and will only be displayed for 120 days. Time series of unit-value or cumulative daily values will NOT be available for retrieval following the 120-day display period. 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.



This station managed by the Louisville District Office.
