SOURCE TYPE SEDIMENT POND
CAUSE: OTHER
CAUSE INFORMATION: Callerf states they have a sediment pond into which the washing water drains from washing the sand and aggregate that
they dig up. They discovered a tickle of the water leaking through the wall of the sediment pond into the Cache La
Poudre River. They estimate very approximately that 10 gallons may have leaked to the river. They discovered that the
cause was a pipe that had been in place for several years that had been buried. Somehow a hole had worn through so
that there was a very small leak from the sediment pond to the river.
