Module 3 Water Quality Index

Stream Name: ROBERTS CREEK | Survey Date: May 6th, 2024
Chemical Test Result Q-value Weighting Index Value
Temperature Change: Temperature Not enough data 92.00 X 0.10 = 9.2
Oxygen Saturation: 101.60 99.00 x 0.17 = 16.83
pH (units): 6.52 75.00 x 0.11 = 8.25
Turbidity - JTU: 0.00 100.00 x 0.08 = 8
Total = Water Quality Index (Compare this value to the Water Quality Chart below)
