For the first time in years, river herring are traveling up the Saugatucket River in Wakefield without the help of humans lifting them over a dam during the spring migration.
River herring are an important source of food for other animals. This year the Saugatucket River in Wakefield has a new fish ladder that's easier for river herring to find and swim through. Bryan Sojkowski, an engineer with the U.S. Fish and Wildlife Service, said the new ladder replaces an old one that wasn't well designed.
