USGS Water-Year Summary 2025
351716116363702 014N003E24Q002S
Basin and Range basin-fill aquifers
LOCATION - Lat 35°17'17.58", long 116°36'40.37" referenced to North American Datum of 1983, San Bernardino County, CA, Hydrologic Unit 18090207,
REVISIONS HISTORY -

Elevation, GW, NAVD88 was revised between 12/21/2007 to 12/22/2015 as a result of updating the accuracy of the LSD after completing a HPGPS survey. A new LSD elevation of 2355.05 replaced the old elevation of 2355.7 effectively shifting the elevation data downward 0.65 feet. The Water level, depth LSD ft was not revised.

GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 745 ft. Upper casing diameter 2 in; top of first opening 725 ft, bottom of last opening 745 ft.
DATUM - Land-surface datum is 2,355.05 ft above North American Vertical Datum of 1988. Measuring point: Top of steel casing, 3.1 ft above land-surface datum, Jul. 3, 1997 to Sep. 9, 1997; Even level with top of steel casing, 1.8 ft above land-surface datum, Sep. 8, 1997 to present; Top of PVC casing, 1.1 ft above land-surface datum, Nov. 4, 2014 to present.  
PERIOD OF RECORD - Water years 1997 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.
 Site consists of 1 continuous record groundwater wells in a multiple-well monitoring site. There is a data gap between Apr. 17, 2013 -Sept. 10, 2013 and Nov. 28, 2017-Feb. 21, 2019 due to instrument failure.
 
PERIOD OF DAILY RECORD - Dec. 2007 to current year.
EXTREMES FOR PERIOD OF RECORD - Highest daily maximum water level recorded, 165.29 ft depth to water below land surface on Sept. 8, 1997; lowest daily minimum water level recorded, 207.71 ft depth to water below land surface on Jan. 26, 2009.
