USGS Water-Year Summary 2023

Basin and Range basin-fill aquifers
LOCATION - Lat 37°37'54", long 118°50'17" referenced to North American Datum of 1927, in sec.01, T.4 S., R.28 E., Mono County, CA, Hydrologic Unit 18090102,
REVISIONS HISTORY -

The 7/6/21 discrete water-level measurements was revised and prematurely set to approved. The updated value exceeded twice the accuracy value. This revision occurred because the Data Review Tool in Aquarius was not scaling the WL, depth LSD correctly with the field visit readings. The discrete water-level measurement and continuous water level, depth LSD scaling issues were observed by two users at the same time. These issues led to the approval of an incorrect water-level MP depth. The water-level measurement reading has been corrected and reapproved. 

Site elevation resurveyed resulting in a change in discrete water level above vertical datum between 6/16/2021 - 6/29/2022.
