Lowell, Massachusetts is River Meadow, or Hale's Brook. This brook flows largely in a man-made channel, as the Lowell Connector was built along it. Both of these minor streams have limited industrial histories as well. The bordering towns (clockwise from north) are Dracut, Tewksbury, Billerica, Chelmsford, and Tyngsborough. The border with Billerica is a point in the middle of the Concord River where Lowell and Billerica meet Tewksbury and Chelmsford. The ten communities designated part of the Lowell Metropolitan area by the 2000 US Census are Billerica, Chelmsford, Dracut, Dunstable, Groton, Lowell, Pepperell, Tewksbury, Tyngsborough, and Westford, and Pelham, NH.
