River Wey

Water average height, steady, brown, opaque. Male mallard on water and cloud of midges on bank.

River brown, opaque, high, surging with eddies. Conductivity reading did not stabilise, cycling between higher and lower values.

Water brown, opaque, high (site partly flooded), running fast with surging flow. One of the alder trunks at the site had been broken off, presumably during the storm, and I would think had been swept downstream.

Water level and flow average. Water brown and opaque with no odour or foam. E. coli tested using the R cards (first attempt at this method). Colony numbers on the three cards were 43, 57 and 70 (quite variable), giving a final value of 5667 CFU/100 ml, which is higher than normal. Unfortunately I couldn’t compare directly with IDEXX this time as the lab was closed for Christmas.

River high, surging, brown with eddies and spots of foam. Test site partly flooded.

Water brown, opaque, steady flow, average height, some leaves floating downstream. A male and a female mallard swam past the site.

Water high, opaque, brown with foam, running fast. Floating mat of vegetation drifted past at speed (photo). Testing site very wet and muddy with swan feathers. Flying insect landed on plant (photo).

Water cloudy, green, average height, steady flow. Lots of damsel flies and pondskaters. One swan passing by.

River cloudy but clearer than usual. Sample clear. Lots of pondskaters. Yellow flowered water lilies. Birdsong. Small fish near bank, bigger fish in middle of river. Damsel flies. Two swans.
Water temperature measured with the same thermometer as air temperature was just below 17 degrees. The thermometer seems to measure consistently about a degree lower than the conductivity meter.

Water hemlock? (See photo)
Water lily leaves
Dragonfly (small)?
Damselflies (probably common blue)
Pondskaters
