Notes

The tests were conducted just before the 1st pool (the water in the pool is usually much clearer - this could be due to a storm we had a few days ago. The water before the pool where the sample was taken was clear). Sunny autumn day! :)

Location description
Near the source of the stream, the water is moving downhill (relatively fast). There are a few "pools" further down. Lots of big rocks with moss growing over them.
