(Richmond, IN)--Some work is coming to improve the pond at Glen Miller Park in Richmond.  That includes dredging.  Here’s Park Superintendent Denise Retz:  "The last time it was dredged was 1972.  We also are concerned when we dredge that the spillway is something that we want to make sure is intact.  There are some cracks in the spillway."  Work has already been done to remove an invasive plant species called tree of heaven from around the pond as part of a stabilization process.
