CSO/SSO Reports and Files (33 files)

Montague's CSO outfalls are located along the Connecticut River, adjacent to Power Street (downstream of the Turners Falls Dam) and Greenfield Road (below the Poplar Street put-in) in Turners Falls. CSO events may impact these area and any areas downstream as deicted in the mas above.

CSO overflows include stormwater that include, or likely include, some quantity of untreated or partially treated sewage and waste. 

 

Precautionary measures to be taken by the public following a CSO discharge event:

Avoid contact with these water bodies for 48 hours after the discharge or overflow ceases due to increased health risks from bacteria and other pollutants. See above for more information on whether specific resource areas, such as bathing beaches, are affected.
