 Please clean out the sediment delta formed at Pond E and fill in the rodent holes obs erved on the pond
embankment.
Pond D was holding water and discharging. The embankment appears stable and the primary and emergency
spillway was clear and functional.

Pond C was dry and not discharging. Overall the embankment is vegetated and stable. However the eastern end
of the embankment has fairly sparse vegetation established. Mr. Watterson and Jerry Nettleton indicated that TC
will be conducting some seeding this fall and this embankment is on the list to be seeded.

Pond B was discharging. TC cleaned out the upper cell of the pond. The primary spillway was clear and
functional.

Pond T was holding a small amount of water and was discharging a small trickle out of the v -notch weir. The
embankment was stable and vegetated. The primary spillway culvert is surrounded by cattails that should be cut
back. The emergency spillway was clear and functional.

The Area No. 1 Pond was holding water and discharging into Pond D.
