USGS Water-Year Summary 2023

02214590 BIG INDIAN CREEK AT US 341, NEAR CLINCHFIELD, GA

LOCATION - Lat 32°25'36.1", long 83°38'39.5" referenced to North American Datum of 1983, Houston County, GA, Hydrologic Unit 03070104, Approximately seven miles south east from Perry, GA, and 1.5 miles north of Clinchfield, GA.

DRAINAGE AREA - 154 mi². revised.

REVISIONS HISTORY -

WDR GA-2013: Drainage area.

The maximum peak streamflow was revised for the 2020 water year. The 2020 water year peak streamflow occurred on 04/20/20 and was estimated over 10% higher from the discharge output from the expanded rating table when a straight line extension was added to Rating 3.0. Rating 3.0 was created after the 04/20/20 peak occurred, however it was used to aid in the estimated discharge on 04/20/20 as the rating was created after high flow measurements were performed.

Gage datum was revised on December 7, 2021 based on an error in the determination of the gage datum.
