- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.
Holocene Alluvium
In August 2024 it was discovered that this site's elevation value had been incorrectly entered into the legacy NWIS site file. The elevation entered was 4240 feet above NGVD29 (based on a manual interpolation between contour lines on the Hereford, AZ USGS topo quad). Upon review, it is clear that the elevation should have been entered as 4140 feet above NGVD29 (likely, a typographic error in data entry occurred). In the process of correcting this error, published water level elevations for all measurements from 1987-1990 at this site were recomputed and republished (note that no changes were made to the actual measured water level value of depth below land surface). Accuracy of interpolated land surface from this top is +/- 12 feet (based on 25 foot contour interval of the map). The site elevation of 4140 feet above NGVD29 is in effect through 12/31/2023 for the computation of water surface elevation from measurements of depth to water.
On January 1, 2024, the site elevation is updated to 4151.58 feet above NAVD88 (accuracy +/- 0.24 feet) based on a GNSS level 1 survey completed in June 2024.
