Stream Name: NELSON CREEK | Survey Date: January 29th, 2022
Chemical Test	Result	Q-value	Weighting	Index Value
Temperature Change: Temperature	Not enough data	92.00	X 0.10 =	9.2
Oxygen Saturation:	88.00	95.00	x 0.17 =	16.15
pH (units):	6.20	65.00	x 0.11 =	7.15
Turbidity (cm):	0.00	70.00	x 0.08 =	5.6
Total = Water Quality Index (Compare this value to the Water Quality Chart below)				38.1
