This lake is connected to the cooling water of the main ring moat and hence
it stays open longer in the winter than any of the other large lakes on site.
Consequently it is probably the best location on site for overwintering
waterfowl. In the early spring
Common Mergansers and
Common Goldeneyes accumulate on the
lake just before dusk and can often be seen performing their courtship displays.
It is also a very good spot for geese and all the species that have been
recorded on site can be found here most years. Not surprisingly, this lake has
produced an impressive list of rarities:
Black Scoter (1997),
Long-tailed Duck (2004),
Red-necked Grebe (1994),
Iceland Gull (2001), and
Glaucous Gull (2002).
