Schwerin Creek WMA Hagen Tract 2

The proposal includes full reconstruction of a earthern berm with outlet structure. Approximately 10 feet of the existing corregated metal pipe on the downstream side of the berm has rusted and fallen off. This now shorter pipe on the downstream side of the berm generates increase velocity and has created a scour hole which is eroding back into the embankment. The riser pipe in the wetland pool has also rusted and stop logs can no longer be held to manage the pool within the wetland. The berm is leaking and the wetland pool will go completely dry by July of each year. The berm will be fully removed to replace the drop pipe structure, anti-seep collar and conduit. The earthen berm will be raised two feet and a new emergency spillway will be constructed. Native grass seed mix will be used on all exposed soil including the berm.
