River Wey

First conductivity test showed 628 μS/cm. Tested again and got 417.

pH square so clear that per the scale it looked like it could be lower than 6 even (assuming test is working ok - box of test sticks is quite old).

pH square quite faint - noticeably lighter than the 6.4 lowest on the test. Guessed at 6.2 given the differences between shades.

Water still by bank, slow in middle of river
No animals at all

Water at test site still, very slow movement in centre of river
