The Annapolis River in Bridgtown
The two square ponds on the north bank of the river upstream from Bridgetown are part of the Carleton Corner wastewater treatment plant. They are settling lagoons, and can be accesed at the the end of Washington Street.
The bridge over the east and west banks of the Annapolis River is part of the Annapolis Valley Trail System. I have previously made a post about the history of the bridge.
