USGS Water-Year Summary 2024
351303119251403 031S024E20F003M
LOCATION - Lat 35°13'03.6", long 119°25'14.5" referenced to North American Datum of 1983, in SE 1/4 SE 1/4 NW 1/4 sec.20, T.31 S., R.24 E., Kern County, CA, Hydrologic Unit 18030003,
REVISIONS HISTORY -

When the site was established on 12/30/21 an elevation of 466 feet above NAVD88 was determined for the land surface datum (LSD) using a digital elevation model (DEM). On 3/31/22 a Level II GNSS survey was completed to determine the elevation of LSD more accurately. A new elevation of 472.27 ft above NAVD88 was calculated for the LSD. The water level elevation above NAVD88 was recalculated for the discrete groundwater levels measured on 3/31/22, 6/6/22, and 6/7/22. The depth to water below land surface measurements were not affected by this change.   

GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 1,835 ft. Upper casing diameter 1.94 in; top of first opening 1,815 ft, bottom of last opening 1,835 ft.
DATUM - Land-surface datum is 472.27 ft above North American Vertical Datum of 1988. Measuring point: Black mark on top of PVC casing, 0.47 ft below land-surface datum, Dec. 13, 2021 to present; Even level with top of vault, 0 ft above land-surface datum, Dec. 13, 2021 to present.
PERIOD OF RECORD -

Water years 2022 (partial) 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.

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

PERIOD OF DAILY RECORD -

April 1, 2022 to current year.
