USGS Water-Year Summary 2021
11206500 Middle Fork Kaweah River near Potwisha Camp, CA
LOCATION - Lat 36°30'47", long 118°47'27" referenced to North American Datum of 1927, in NE 1/4 NE 1/4 sec.26, T.16 S., R.29 E., Tulare County, CA, Hydrologic Unit 18030007, in Sequoia National Park, on right bank, 0.25 mi below diversion dam, 0.5 mi southeast of Potwisha Camp, 0.7 mi upstream from confluence with Marble Fork Kaweah River, 8.1 mi northeast from Three Rivers, and 30 mi northeast of Visalia.
DRAINAGE AREA - 102 mi².
REVISIONS HISTORY - WSP 1930: Drainage area.
PERIOD OF RECORD - July 1949 to current year (since October 2003, low-flow records only). Monthly discharge only, for water years 1956-57, published in WSP 1735. Prior to October 1954, records for river and conduit published separately. October 1954 to September 1955, October 1957 to September 1962, combined flow only; October 1962 to September 2002, river only, and river and conduit combined. CHEMICAL ANALYSES: Water year 1980. SPECIFIC CONDUCTANCE: Water years 1980-81. WATER TEMPERATURE: Water years 1959-63, 1972, 1980-81.
GAGE - Water-stage recorder and rectangular flume. Elevation of gage is 2,100 ft above NGVD of 1929, from topographic map. Prior to October 1955, at datum 0.70 ft higher.
COOPERATION - Records provided by Southern California Edison Co., under general supervision of the U.S. Geological Survey, in connection with Federal Energy Regulatory Commission project no. 298.
REMARKS - Middle Fork Kaweah River Conduit No. 3 diverts from left bank of Middle Fork Kaweah River, 0.1 mi upstream from station. Flow from this conduit joins that of Marble Fork Kaweah River Conduit No. 3 and is returned to Kaweah River 2.7 mi downstream from confluence of Marble and Middle Forks. The record of combined discharges of river and conduit was discontinued September 2002 when the two conduit gages near the points of diversion (stations 11206000 and 11207500, respectively) were replaced with one nonequivalent conduit gage at the powerplant (station 11208565). Beginning October 2003, no records computed above 38 ft³/s. See schematic diagram of Kaweah River Basin available from the California Water Science Center.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 46,800 ft³/s, Dec. 23, 1955, gage height, 29.0 ft, from floodmarks, datum then in use, on basis of slope-area measurement of peak flow; minimum daily, 0.1 ft³/s, Nov. 12-15, 1949.
