This table captures common units used within water datasets. A brief description of the columns is provided below:
Category: Describes the general type of data being discussed. The entries coincide with those used for organizing Standards Development content.
Measurement Type: Describes the general phenomenon being measured.
Units: Captures the common units used for the measurements. Where relevant, common conversion units are also provides (e.g., parts per million = milligrams per liter)
Data Types: Contains a list of water data entries that are usually measured for a given measurement type and unit
Notes: Additional nuances worth being mindful of for a given measurement or data type

For reporting of water data
Water quantity data include measurements of
a. streamflow (CFS) instantaneous
b. lake/reservoir levels (Feet),
c. Reservoir volume (acre-feet) accompanied by area-capacity table
d. groundwater levels (Feet, below ground surface)-usually feet below measuring point accompanied by elevation of measuring point and elevation above ground of measuring point-could look at the parameters in USGS NWIS to spell out every last detail
e. Soil moisture (volumetric water content)
f. Precipitation (inches)
g. evapotranspiration (percent of precipitation)
Water quality data include measurements of the -not sure we should even begin to list these parameters and their units…radionuclides, fecal coliform, you could look at the list of water quality standards for NM or just refer to the standards
a. Trace metals (ppb) * need a separate listing – see USGS – very long list
b. Major ions (ppm) * need a separate listing – see USGS – there are so many
c. Water temperature (C)
d. Dissolved oxygen (mg/L)
e. pH (pH units)
f. nutrients
g. specific conductance (uS/ cm at degrees 25 C)
h. turbidity (NTUs?)
i. ecosystem health data and biological parameters (presence / absence)
Water use includes measurements of volumes (are they all (ac-ft/year)?
a. Water rights or permits (ac-ft/year) look at WATERS to see all the parameters they include that are associated with a water right-I added a few.
b. Diversions ac-ft?-it varies, depending on the water right
c. Withdrawals-same as diversions

f. return flows
g. transfers (interbasin? )
h. wastewater discharge
i. reused wastewater
j. point of diversion
k. type of diversion (well, spring, surface water)
l. place of use
