Notes

Regression models were updated in Kramer and others (2021) and the newest version of the model was applied beginning January 1, 2021. This model was developed using a model calibration dataset with YSI 6-Series model 6136 turbidity sensor data. The computed data uses real-time turbidity data from a YSI EXO turbidity sensor. There are known sensor differences that can affect computations. More information detailing sensor differences, models, period of application, and computed concentrations can be found in Kramer and others (2021).
