LOCATION - Lat 35°00'57.10", long 106°37'02.34" referenced to North American Datum of 1983, in SE 1/4 SW 1/4 SW 1/4 sec.10, T.9 N., R.3 E., Bernalillo County, NM, Hydrologic Unit 13020203,
REVISIONS HISTORY -
Well casing failed and well began to fill with mud around April 1, 2009. After review and comparison with continuous water levels from the deep Mesa del Sol well (345758106364001) the period of record from April 1, 2009 to June 12, 2015 was determined to be unrepresentative of water level conditions in the aquifer. Prior to June 18, 2024 the datum of the site was 5100 ft above NGVD29 (determined via topographic map) and updated to 5094 ft above NAVD88 (determined via Lidar) on September 15, 2017. Discrete water levels have previously been published on NWIS Web using old datum(s).
