CASTLE NECK RIVER

Owned by Bostik Inc., this stone and wood dam is the last dam encountered along the mainstem of the Ipswich River. The dam does not have fish passage and therefore obstructs over 56 river miles from migratory fish access. There are several tributary streams upstream of the South Middleton Dam that would be opened to fish migration following dam removal. Dam removal also has the potential to restore access to over 119 acres of historically important spawning ponds for Alewife. The dam is listed as a significant hazard dam by the MA Office of Dam Safety and is showing significant signs of wear that will eventually need to be addressed for the dam to remain in place. Thankfully, Bostik, Inc. has decided to remove the dam and progress has been made towards that goal.
