USGS Water-Year Summary 2024
324307117063505 017S002W05Q005S
LOCATION - Lat 32°43'08.16", long 117°06'35.81" referenced to North American Datum of 1983, in SE 1/4 NE 1/4 SW 1/4 sec.05Q, T.17 S., R.2 W., San Diego County, CA, Hydrologic Unit 18070304,
REVISIONS HISTORY -

Revisions: Between 9/4/2019 and 12/9/2019 the incorrect conversion of input equation was used. The equation did not contain parenthesis so the mathematical order of operations was performed incorrectly. To fix this, the raw values from the EDL data were put into an Excel spreadsheet along with the correct equation to provide the correct WL in feet below LSD. 

Discrete water-level readings for NAVD88 and NGVD29 values were updated due to an incorrect offset that was originally applied. The changes were made to the values from the start of the record through May 18, 2021.

GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 250 ft. Upper casing diameter 1.94 in; top of first opening 230 ft, bottom of last opening 250 ft.
DATUM - Land-surface datum is 84.7 ft above North American Vertical Datum of 1988. Measuring point: Black mark top of 2 inch PVC casing (below LSD), 0.64 ft below land-surface datum, Dec. 29, 2011 to present; Even level with top of vault directly over casing (above LSD), 0.5 ft above land-surface datum, Dec. 29, 2011 to May. 6, 2020.
PERIOD OF RECORD - Jan. 7, 2012 to Oct. 31, 2021.
GAGE - Electronic data logger and pressure sensor.
REMARKS - Records rated good. Sudden water-level changes may be attributed to nearby anthropogenic effects such as pumping and sampling. Home & Federal Cluster Wells consist of six continuous record groundwater wells, located in a common ground-level vault.
PERIOD OF DAILY RECORD - Jan. 7, 2012 to Oct. 31, 2021.
EXTREMES FOR PERIOD OF RECORD - Highest daily maximum water level recorded, 1.03 ft NAVD 88, Mar. 17, 2012; lowest daily minimum water level recorded, -9.12 ft NAVD 88, Oct. 26, 2021.
