Charles River
“In May, the Charles hosts the run of thousands (millions?) of alewives swimming upstream to spawn, accompanied by black-crowned night herons, great blue herons, double-crested cormorants, ospreys, and other predators. I have seen large turtles, 2-foot-long carp, common mergansers, bufflehead ducks, muskrats, Norway rats, and Canada geese from these vantage spots.” Rob Gogan, Recycling and waste manager, Facilities Maintenance Operations
