A Look at Exeter’s Fish Ladder

Several weeks ago on a soggy gray day, mister gardener attended a presentation by New Hampshire’s Fish and Game Department at Exeter’s fish ladder. The public was invited to see what fish were making the annual spring trip around the Great Dam taking them from salt water to fresh water.

Fish LadderThis is the location where fresh water of the Exeter River flow into the salty Squamscott River. The dam was constructed hundreds of years ago when the town was settled by Europeans to power sawmills, grist mills and more. Naturally, it was an obstacle to the fish that needed to migrate from salt water to fresh water to spawn. With the mills gone and a fish ladder in place, they have restored the natural habitat for such fish as smelt, alewife, blueback herring, American shad, American Eel and sea lamprey.

A small crowd gathered at the street and made the short walk downhill to the river.

Lamprey and more fish.
