Stream Name: GRAVELL CREEK | Survey Date: November 16th, 2019
Chemical Test Result Q-value Weighting Index Value
Temperature Change: Temperature Not enough data 90.00 X 0.10 = 9
Oxygen Saturation: 96.00 98.00 x 0.17 = 16.66
pH (units): 7.47 93.00 x 0.11 = 10.23
Turbidity (cm): 0.00 80.00 x 0.08 = 6.4
Total = Water Quality Index (Compare this value to the Water Quality Chart below)
