A brief visit after work to No.6 tank unlike yesterday did produce the juvenile Black-necked Grebe that put on a good performance in the choppy waters.
The water level is higher due to a combination of sludge pumping into the tank and recent heavy rains. The wader species have been accordingly affected. Hopefully higher tides might bring them back again. There were 3 Ruff, 15 Common Snipe and c350 Black-tailed Godwit.
The usual species of ducks again included the drake Common Pochard.
