Kennebec Estuary Land Trust is sponsoring a series of five programs at the Nequasset Fish Ladder on April 21 to celebrate World Fish Migration Day. These free programs will include birding, kid’s story hour and activities, canoe/kayak on Nequasset, a tour at the ladder about the fish count and harvest and a presentation at the town office about the history of Nequasset dam and fish ladder.

Each of these programs will last about an hour:

• Birding at Nequasset is scheduled from 9:30-10:30 a.m. Meet at Nequasset Park and join land trust staff and volunteers to identify birds around the ladder and lake.

• The kids’ story hour and activities program is scheduled from 11 a.m. to noon. It will feature a story about alewives, interactive games to learn about alewives and their migration, and alewife focused crafts.

• The canoe and kayak paddle on Nequasset Lake will be from 12:30-1:30 p.m. Bring your own boat. Local experts will lead a tour around the lake, an introduction to the alewife harvest and information about the way uses of the lake have changed over time.

• From 2-3 p.m.:, land trust staff, volunteers and a member of the Woolwich Fish Commission will discuss alewife migration across the state, the design of the ladder, the number of fish that are annually harvested or spawn in the lake, and how to take part in KELT’s annual fish count.

• From 3:30-4:30 p.m., Woolwich Selectboard member Allison Hepler and Woolwich Fish Commission member Bill Potter will give a presentation about the history of Nequasset Lake, Nequasset Dam and the Nequasset alewife harvest at the Woolwich Town Office.
