Model Form #1

log₁₀(TSS) = - 0.83 + 1.16 log₁₀(TURB) + 0.000605 SC

where:

TSS is computed total suspended solids, in milligrams per liter
TURB is turbidity, YSI model 6026, in formazin nephelometric units
SC is specific conductance at 25 degrees Celsius, in microsiemens per centimeter

Notes

This model is used to compute values at this station only from 1999 through 2006, the range of time when a 6026-model turbidity sensor was used. Beginning in 2007, a 6136-model turibidty sensor was installed, resulting in a change to the model.
