Abington has two major waterways; the Shumatuscacant River to the west provides the town's border with Brockton, and Beaver Brook runs through the eastern part of town; it was the source of much of the water power used by the shoe factories. In the northwestern corner of town lies Ames Nowell State Park, a large forested area around Cleveland Pond. Island Grove Pond was created in the 1700s, when a dam was built on the Shumatuscacant River. Much of the town's population is centered on the eastern side of town, closer to the former town geographic center. The northeast corner of town is also the site of portions of the runways of the South Weymouth Naval Air Station, which was closed in 1997 as a part of the fourth round of BRAC base closures.
