Okay, so here's the story. There are two pipes. One was to bring rising water from "swamp" or low point, into the small brook, which was always there. In the past 20 years, another large pipe, that would bring groundwater and overflow to the Long Island Sound, broke, exactly at our spot, and now we have all that water coming into our "brook" which is not longer a brook. So the brook was originally to catch overflow water, but now needs to manage the tremendous amount of water that comes in via the broken pipe.
