In April 1999 Congress designated 29 miles of the Sudbury, Assabet, and Concord Rivers as Wild and Scenic for their outstanding ecology, history, scenery, recreation values, and place in American literature. The designated reach includes: the 14.9-mile segment of the Sudbury River beginning at the Danforth Street Bridge in Framingham, downstream to the Route 2 bridge in Concord, and the 1.7-mile segment of the Sudbury River from the Route 2 bridge downstream to its confluence with the Assabet River at Egg Rock; the 4.4-mile segment of the Assabet River beginning 1,000 feet downstream from the Damonmill Dam in West Concord, to its confluence with the Sudbury River at Egg Rock in Concord; and the 8-mile segment of the Concord River from Egg Rock at the confluence of the Sudbury and Assabet Rivers downstream to the Route 3 bridge in Billerica.
