"For the first time since the Civil War, river herring (both Alewife and Blueback herring) made their way to the Upper Mystic Lake on their own."
That's according to an announcement from the Mystic River Watershed Association.
According to the association, an estimated 198,932 herring made it up the Mystic River on their own to Upper Mystic Lake in Medford, Arlington and Winchester, which is their most desirable spawning habitat.
More than 85 volunteer fish monitors observed the herring run and logged 685 observations, which allowed the Mystic River Watershed Association to estimate the total herring run, according to the announcement.
"It's an exciting new program, and we're happy with the first year's results," said Katrina Sukola, a watershed scientist quoted in the announcement.
