Weather Forecast
The probability of CSO discharges increases during wet weather.
Buffalo Sewer has developed this notification system to alert the public of the occurrence of combined sewer overflow (CSO) events. During wet weather, stormwater enters the sewer system, combining with wastewater, often leading to permitted CSO discharges. These discharges are the result of the historical design of the system to prevent basement flooding. Buffalo Sewer is working to eliminate the effects of CSO’s on our Great Lakes waterways. As our efforts to address CSO’s continue, we want to make sure to notify the users of our waterways about the pollution concerns. As many other conditions affect the water quality of our waterways, we urge users to use care during recreation. Please be advised that the information displayed in this map is based on a computer model and may not represent real-time activity. Buffalo Sewer continues to update the model to better reflect actual conditions.
