At this site, real-time estimates of water quality depend on the availability of instantaneous discharge and specific conductivity measurements. During winter months, real-time water quality estimates may not be available for this site due to effects of ice.
Model Form #1
ln(DSR) =
- 0.7738 + 1.0322 ln(SC)
where:
- DSR is computed diss. solids, in milligrams per liter
- SC is specific conductance at 25 degrees Celsius, in microsiemens per centimeter
