Unstead Wetland Reserve

Virtually dry although I could hear a faint trickle of water passing through the brick tower/bat roost. The lack of water relates to the 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)

Exit (Battery) almost dry (and very overgrown) so no sample could be taken.

Nitrates v high!

Very high Nitrates (and fairly high Phosphates)

Pretty grown over so hard to get sample. Both Nitrates and Phosphates high this month (despite lots of rain?)

High in Nitrates, but low in Phosphates

Very overgrown so hard to get sample. Nitrates 2 (med/high), Phosphates 0.4 (high).

Very overgrown at sampling spot, so quite hard to get a sample. Both Nitrates & Phosphates high again.

Heavily overgrown, but path cut back to provide access to outlet pool.
No Phosphates but Nitrates very high.

The surface had more foam than usual and what looks like threadlike mats of brown algae. The phosphate reading also seems high (0.3) and nitrate (4). This could be due to having been intentionally dropping water levels in the new scrapes and barrowing in some shingle (so some ground disturbance).
