Souhegan River Protected Instream Flow
The upper and lower reaches of the Souhegan River, designated in 2000 were the subject of a Protected Instream Flow Study between 2005 and 2008. Protected instream flow criteria for the upper and lower reaches of the Souhegan River were accepted in 2008, and slightly modified in 2013. The Souhegan River Water Management Plan was completed in 2013.
