Colowyo G 1981-019 16 October 2007 Pg 3/6 c~ Hydrologic Balance (cont.): -The East Taylor Pond (NPDES O1 OA) contained a small amount of water (to the bottom of the riser pipe at the bottom of the pond) at the time of the inspection. The pond embankment was well vegetated and appeared to be stable at the time of the inspection. No erosional problems noted on the embankment at the time of the inspection. The emergency spillway is an open, trapezoidal riprapped channel. The spillway was stable and well maintained at the time of the inspection. -The Prospect Pond (NPDES 007A) contained water approximately three feet below the top of the discharge pipe but was not discharging at the time of the inspection. Due to the large amount of water and debris that entered the pond, the weep-hole on the riser pipe plugged up. There was a large amount of new sediment that entered the pond during and after the last big storm event. The pond embankment was well vegetated and appeared to be stable at the time of the inspection. No erosional problems noted on the embankment at the time of the inspection. The emergency spillway is an open, trapezoidal riprapped channel. The spillway was stable and well maintained at the time of the inspection. Prior to the recent storms, Colowyo had estimated that there is approximately 4,000 yards of material in the pond that will be cleaned out this year. This amount has increased, as mentioned above. - The Gulch A Pond (NPDES 004A) contained waterjust below the bottom of the discharge pipe and was not discharging at the time of the inspection. The pond embankment was well vegetated and appeared to be stable at the time of the inspection. No erosional problems noted on the embankment at the time of the inspection. The emergency spillway is an open, trapezoidal riprapped channel. The spillway was stable and well maintained at the time of the inspection. Goodspring Creek was flowing (relatively clearly) at the time of the inspection. -The Section 16 Pond (NPDES 009) contained water approximately eight feet below the riser pipe and was not discharging 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 an open, trapezoidal riprapped channel. The spillway was stable and well maintained at the time of the inspection. -The Streeter Pond (NPDES 001 A) contained water approximately one foot below the discharge pipe and was discharging through the weep hole at the time of the inspection. The discharge appeared to be clear. The pond embankment was well vegetated and appeared to be stable at the time of the inspection. No erosional problems noted on the embankment at the time of the inspection. The discharge from the Streeter Pond enters Goodspring Creek then flows through a large culvert under Colorado Highway 13. This culvert is owned and maintained by CDOT. The culvert has a grate on the front which is blocked, causing water to back up and create a large "pond" behind it. The water level was very high at the time of the inspection (almost to the bottom of the Streeter Pond flume). Tony indicated that CDOT cleaned this grate about once every six months but he did not know if they had cleaned it yet this year.
