LOCATION - Lat 35°03'59.37", long 106°33'52.45" referenced to North American Datum of 1983, in SE 1/4 SW 1/4 NW 1/4 sec.30, T.10 N., R.4 E., Bernalillo County, NM, Hydrologic Unit 13020203,

REVISIONS HISTORY -

The period of record from 2015-11-03 to 2016-11-14 was revised because the 2016 aquifer test discrete values were revised to correct a systemic MP correction error.  The new MP correction makes the new depth to water 0.76 ft deeper than previously. Prior to June 04, 2024 datums published for this site included: 5350.30 ft above NAVD88, 5349.94 ft above NAVD88. The measuring point height of MP-1 was updated from -0.33 feet  to -0.38 feet based on survey data collected in June 2016 and then updated to -0.35 feet based on a reevaluation of the survey data in 2024. Discrete and continuous water level data were published on NWIS Web using the previous datum and MP values.
