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(LDS) =
2.7463 + 0.6795 ln(Q)
where:
- LDS is computed load diss. solids, in tons per day
- Q is computed discharge, stage-discharge rating curve, in cubic feet per second
