2 PM hole through
bottom of dam just
above where I killed the ? last year,
has completely drained this pond.
Level dropped 18". The former bottom
is still wet so the damage is probably
fairly recent. A bank burrow has been
exposed. The same thing has happened
to the second dam below "flash tree"
dam and the level has been lowered
about a foot. Have no idea as to
what might have done this. Left 2:40.
Aug 29 Arr. 2:40 to do asp samples D-G
