Macro invertebrates and Water Chemistry

Today we went upstream in the Wood Cock dam area. 

Temperature: 20*C

PH: 7.1

Total dissolved solids: 120

Turbidity: 20

Dissolved Oxygen: 13.5

Alkalinity: 126.5

Nitrogen: 0.5

Phosphorus: 0

Pollution Toleration Index: 36.4 (Which is Fair)

Number of Taxa: 9

We found different macro invertebrates than yesterday. We found 3 Water Penny larvae. That's really exciting because the Water Penny Larvae show good signs good water quality.We also 3 Crayfish. We didn't find any yesterday downstream. So it was pretty nifty. 

There was a less abundance of different species. We found 9 different species compared to the 16 from yesterday. The 9 species we found show signs of good water quality because they are sensitive to pollution.

Love,
