USGS Water-Year Summary 2022
09378170 SOUTH CREEK ABOVE RESERVOIR, NEAR MONTICELLO, UT
LOCATION - Lat 37°50'48", long 109°22'08" referenced to North American Datum of 1927, in NE 1/4 SW 1/4 SW 1/4 sec.02, T.34 S., R.23 E., San Juan County, UT, Hydrologic Unit 14080203, 200 feet upstream from west side of reservoir and 2 miles southwest of Monticello.
DRAINAGE AREA - 8.64 mi².
REVISIONS HISTORY - 10/25/2018 to 10/17/2019 was revised to remove a +0.02 ft datum correction. The correction was removed from the Gage height time-series, all staff gage (SG) readings, and all measurement gage heights (excluding the 10/25/2018 visit). It was determined that the staff reference gage has remained stable and the correction was due to an error in reading an elevation from the staff gage at a prior date.
