Explore the Merrimack

Boating, kayaking or canoeing

Great! You’ll find a wide variety of experiences and environments—ranging from lake-like calm water to fierce (and sometimes dangerous) rapids and tidal flows.

Here is information on each of the four major regions of the Merrimack:

the Four Major regions of the Merrimack:

Lower Mass

From the sea to the Great Stone Dam in Lawrence, 30 miles.  Most of this stretch is tidal, which can present challenges for paddlers—particularly when the tide is going out.  This is the busiest stretch of the river, with thousands of power boats docked at marinas, resting on moorings, or entering via boat ramps.  Many miles of excellent water for powerboating.  Some kayaking happens along this part of the river, but in many areas you’ll contend with wakes and confusing currents.

Upper Mass

From the Great Stone Dam in Lawrence to the New Hampshire border, 19 miles.  A wide variety of boating options (kayaks, canoes, power boats, crew boats).  This region has 2 dams—in Lawrence and Lowell.

Lower N.H.

From the Mass. border to Garvin’s Falls dam in Bow, 35 miles.  This area also supports a good variety of boating options, though it can be shallow and tricky in some parts. Not an ideal place to bring a deep-draft boat.  There are 3 dams—in Manchester, Hooksett and Bow.

Upper N.H.

From Bow to the river’s headwaters, in Franklin—30 miles.  This is the arguably the best region for paddlers.  A wide range of water conditions (ranging from calm to rapids). Long stretches of wild, unpeopled shorelines, this area is eligible for inclusion on the national list of Wild and Scenic Rivers.  Tends to be shallow and rocky in many spots.

This is the time of the year near the mouth of the Merrimack where Harbor Seal pups wean from there mom (4 weeks). Occasionally one of the pups gets tired, injured, or sick. This one made it to the sea safely! Remember federal law prohibits anyone from getting closer than 150 ft to a seal. If you come across a seal on the beach leave it alone. If you think it’s in trouble call the Marine Mammal Rescue Center in Rye, NH at 603-997-9448.

Humpback whales have been feeding on menhaden just outside the mouth of the Merrimack River on both the Salisbury and Plum Island side. Menhaden gather in huge schools that the whales find as easy targets!

It’s that time of year when Piping Plovers hatch in the coastal area of our watershed. These endangered birds lay their eggs out in the open sand. Please keep pets away from nesting areas as they can easily destroy a nest or kill the fragile babies!

The gray seal is a common sight at the mouth of the Merrimack. They often lounge on Badgers Rocks just off of Salisbury. This fella followed Board President, Dan Graovac (@dandydannyg) in his kayak for about half a mile.
