Prior to 11/2/2022, the datum of the gage was 560.54 ft NGVD29.
Prior to Oct. 27, 1959, nonrecording gage at same site and datum.
REMARKS - Records rated fair except for estimated daily discharges and discharges below 5 ft³/s, which are poor. Since water year 1980, at least 10% of the contributing drainage area has been regulated. These structures control runoff from 42.0 mi² in the Hog Creek drainage basin.
