Hydrologic Balance (cont.): - The West Pit Pond (NPDES 008A) contained a small pool
of water and was not discharging at the time of the inspection. The presettling cell
was full. The pond embankment was well vegetated and appeared to be stable at
the time of the inspection. The emergency spillway is a riprapped, open channel
spillway. It appeared to be stable at the time of the inspection. No erosional
problems noted on the embankment at the time of the inspection. There was a lot of
water flowing in the Taylor Creek drainage at the time of the inspection as a result of
snow melt.
- The Stoker Siding Pond (NPDES 005A) contained water approximately four feet
below the top of the discharge pipe and was discharging a very small amount
through a weep hole in the pipe. The discharge looked clean at the time of the
inspection. The pond embankment was well vegetated and appeared to be stable
at the time of the inspection. The emergency spillway is a riprapped, open channel
spillway. It appeared to be stable at the time of the inspection. No erosional
problems noted on the embankment at the time of the inspection.
- The East Taylor Pond (NPDES 01 OA) contained a small pool of water and was not
discharging at the time of the inspection. The pond embankment was well

- The Prospect Pond (NPDES 007A) contained water approximately five feet below
the top of the discharge pipe and was discharging a trickle through the weep hole
on the pipe. Water was also flowing into the pond (from the melting snow) at the
time of the inspection. The pond embankment was well vegetated and appeared
to be stable at the time of the inspection. The emergency spillway is a riprapped,
open channel spillway. It appeared to be stable at the time of the inspection. No

was flowing out of its banks and its flood plain at the time of the inspection. The field
that is in front of the pond was partially under water (up to six inches).
- The Streeter Pond (NPDES 001 A) contained water approximately 18 inches below
the discharge pipe and was discharging through the weep hole at the time of the
inspection. The discharge measured 0.2 on the flume (high for the Streeter Pond)
and appeared to be clear. Water was flowing into the pond from the Streeter ditch.
