The Lake Andrews restoration has turned a previously unusable area of the Bates campus into a major amenity. The sloping ground adjacent to Bates’ new Arts Complex was developed into a much-needed lakeside outdoor performance and teaching facility.

It provides a setting for many uses—outdoor classrooms, theater productions, dance programs, concerts, and ecological and biological laboratories. The restoration and reconfiguration of Lake Andrews creates an environment that gives the campus a new and memorable identity.

In response to heavy siltation and erosion at the pond, a passive runoff filtration system was designed in conjunction with the walkway subgrade. Phosphates are leached from the runoff water and bound to soil particles, where they are used by pond-edge emergent plants as a nutritional source. A dredging program eliminated builtup, polluted sediments in the pond and re-established a sustainable pond bottom profile.
