This is Montague's resource for public notification of Sanitary Sewer Overflows (SSO) and Combined Sewer Overflows (CSO). For additional information regarding Montague's CSO locations, including static maps, please visit our CSO Information Page.
When a discharge or overflow occurs, the Town sends out a public advisory notification. On business days, this website will be updated within 24 hours of the notification. During weekends or holidays, this website will be updated on the next available business day.
You can also see a list of discharge and overflow events on the MassDEP website (link below). This list is updated within 18 hours of when the public advisory notification is sent. Enter Town of Montague in the Permittee field and click “Search.”

CSO Long Term Control Plan: To access the most recent update to the town's CSO Long Term Control Plan (LTCP), click here. Note that this document is also posted below ion a separate file module, along with its several appendices. Based on the LPTC analysis, the Town recently enhanced training and establisheda dedicated collection system maintenance staff position, bringing greater consistency to its operation of CSO reduction assets. The Town has and will continue to submit grant requests and seek Town appropriations to fund other measures that would optimize the effectiveness of the CSO mitigation infrastructure.
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.
