Located at the center of the site , the wetland marsh is an orienting device , a point of focus , and a place to stop and listen to the bullfrogs . Usually filled with water , it holds cattails that filter nitrogen out of upland stormwater that courses over fertilized lawns , stopping pollution of Lake Waban . It also draws unique animal species inward , putting them in full view of visitors while still being protected by vegetation . Before stormwater reaches the lake , it flows over a stone spillway ( made from granite found during excavation ) and becomes reaerated . Together these features form a landscape whose overarching function is to seal off past environmental mistakes so that the land can become a productive part of the campus .
