Unstead Wetland Reserve

The East Lagoon remains dry. There appears to be a blockage stopping water flowing from the 'Dry' Lagoon into the East Lagoon. The warden is not sure what the cause is but he and volunteers will continue to investigate over the coming weeks.
(note the Dry Lagoon was originally dry but is now full of water! One of the first lagoons to be refilled when volunteers started working on the site)

East Lagoon still dry (for about 3 months now) so no sample taken

Both Nitrates and Phosphates low

Re-filled since last month (when it was drained to allow cutting of willow beds at back).

East Lagoon has been drained to cut encroaching willows, therefore it was not possible to take a water sample (and likely that the sediment will have been stirred up when it is reflooded).

Low Nitrates, but high Phosphates. East Lagoon is being drained to allow cutting encroaching Willows, hence flow in from culvert has been blocked off for a few days. This might account for the high Phosphates?

Lots of duckweed covering surface, shading out blue greens. Low Phosphate & Nitrate.

Duckweed covering surface and no sign of any blue/gree algae in water (see in June's test). Low P & N this time.

Both Nitrates & Phosphates low today. Looks like an algal bloom is developing. Hard to see on the photo but looks like clouds of single celled algae on mud bottom (easily disturbed and not strands and not on surface).

Nitrate & Phosphate both very low today. Water levels seem quite high. Duckweed starting to cover water surface.
