About: Scott Comings, associate state director for The Nature Conservancy, will lead a presentation titled “Pawcatuck River Fish Passage Projects” about TNC’s efforts to reconnect the lower Pawcatucket River for river herring. Removal of the Bradford Dam will benefit fish, create less flooding and open up the river to paddling. The pot-luck dinner begins at 6 p.m., followed by the presentation at 6:30. Space is limited.
