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.

Happy Thanksgiving from everyone at MRWC. Whether you volunteer, donate, or advocate for the river, we are grateful for your contribution to preserving the Merrimack!
We had a great time collecting water quality data from the Shawsheen River with students from Lawrence High School. The data is helpful for comparison with a 2015 study in the same area-- we found that the E. coli concentration is much lower in 2022. 

Our education programs would not be possible without your support. To contribute to education for youth and adults alike, click the "support us" link in our bio.

The Merrimack River Watershed is rich in history!

This fall, your investment in the watershed will ensure that the MRWC continues our work towards clean water for all.  Your support helps us monitor water quality, offer educational programming, and host public cleanup events.  Please click the donation link in our bio to help us protect the Merrimack!
You might think that we harness the Clean Water Act, meant to reduce and eliminate water pollution, to protect our drinking water sources... That would make sense, but it’s not what is happening.
Are you as fascinated as we are about old maps of the Merrimack River Watershed?

Take a look at this map from the Norman B. Leventhal Map Center Collection. The year is 1832, the location is the City of Haverhill.  The description says " Partial cadastral map showing names of  land owners, roads, the Merrimack River, other drainage, parish divisions, vegetation, and names of surrounding towns in New Hampshire and Massachusetts."
Today is #NationalPhilanthropyDay, where we celebrate the generosity of our supporters and the incredible impact we have made together in the Merrimack River Watershed. Because of you, in 2022, here are a few of our accomplishments! 

Thank YOU!
