USGS Water-Year Summary 2023

354048119445004 026S021E07J004M

LOCATION - Lat 35°40'48.58", long 119°44'50.75" referenced to North American Datum of 1983, in NE 1/4 SE 1/4 sec.07, T.26 S., R.21 E., Kern County, CA, Hydrologic Unit 18030012,

REVISIONS HISTORY -

Originally published water level of 275.43 made on 2020-09-11 at 18:01 UTC was changed to 276.43 by reverett on 2021-09-13.The transducer data and discrete water levels made on 2020-06-29 and 2020-09-18 suggest this water level should be 1 foot deeper. It is believed a typo occurred when entering the original water level measurement.

Groundwater elevation, NAVD88, between 1/19/23 to 3/29/23 was lowered 0.46 ft. The land surface elevation of the site was updated from 272.55 to 272.09 on 1/19/23. The conversion from water level, depth below LSD, to groundwater elevation, NAVD88, did not process correctly and continued to use the original elevation. The problem was resolved on 7/25/23 and the elevation data between 1/19/23 and 3/29/23 was changed to the correct values.

PERIOD OF RECORD -

Water years 2018 to current year.

GAGE -

Electronic data logger and pressure sensor.

REMARKS -

Record is rated good. Sudden water-level changes may be attributed to nearby anthropogenic effects such as pumping and sampling or natural events such as earthquakes (July 2019).

Site consists of five continuous record groundwater wells, located in a common ground-level vault.
