Site Observations:

  1. Mechanical damage or joints parting
  2. Structural Problem

Comments: PLMP 92.36. This culvert connects two ponds together. For this reason no stream widths were taken. It is an old pipe and the outlet has begun to rip apart. The outlet is also rusted through. Fish swirls were seen during the survey and a fish was seen jumping as well.
