Staff from the Kennebec Estuary Land Trust plan to give a presentation from 10 to 11 a.m. Saturday, May 21, at the Nequasset Fish Ladder, to discuss alewife biology, life history, and the history of the alewife run at Nequasset Lake in Woolwich.

This presentation is free, according to a news release from the Bath-based trust.

May 21 is World Fish Migration Day, a day of international celebration for open rivers and migratory fish that includes events at fish migration sites in 60-plus countries across the world.

The alewife run is underway at Nequasset Lake, so during the program attendees can watch fish climb up the ladder, see an active alewife harvest, buy smoked alewives for 75 cents apiece, and potentially spot one of the ospreys or eagles that are drawn to the site by the abundant fish.

The best parking is at Nequasset Park. The park is located on George Wright Road in Woolwich, just to the east of the intersection with Nequasset Road. Registration is not required, but it is appreciated for help with program planning.
