Many more ducks are usually present on Oaks Slouth. The water was
unusually low.
Aqustic plants present included a Cyperaceae around the edges. No
seed heads could be found. It appeared as though no seed pro-
duction took place this year. Lots of Polygonum was pre-
sent. Some Eleocharis, An abundance of Bidens, considerable
amount of Ricciocarpus. Also a grass (submerged) which I have
yet to identify.
