** The NF Long Canyon Creek
Diversion Dam is approx. 10 feet high.
Water may get as deep as the height of
the dam while water is diverted through
the pool. However, PCWA stops water
from diverting through the diversion
pool in July of each year. At the time
this survey was conducted (August),
water in the pool was less than 1 foot
deep, with some areas of exposed
mud/dirt. Thus, water does not remain
in the diversion long enough to support
a breeding population of CRLF.
