Here are all the reported sewage overflow totals for Jacksons Bay Barry in 2024.
We use data from the water companies, but we are seeing many anomalies that make us believe that bathing location information is quite poor. The situation is likely far worse than reported here.
If the locations of the sewage outlets look a bit unusual, it is likely that the reporting of the data from the water company is in error. We rely on their data in order to draw these maps.
Other CSO Combined Sewage Overflow - a device that, when operating, pours combined rainwater & sewage into a waterway s may also be located nearby, however the water companies claim that these do not affect the water quality here.
