People prefer to believe in bogus B.S. The truth is that when the river rises to cover the drainage pipe for Swan Pond, the pressure is on the river side and it leaks in. Every time.
What was a nice lawn and even a place where kids played soccer and ice skated in season is now swamp-like — for weeks — every time the river rises. It will always be that way as long as that pipe and “boot” are there. So this planting project won’t restore it.
