Last Wednesday morning, after paddling 6 miles up the Pemigewasset River (north of Franklin, NH), I reached my main objective for the day, Sumner Island. The paddling was well suited to this primarily flatwater paddler. Unlike the whitewater sections of the Pemigewasset, this section had sufficient depth to allow my boat's passage above the rocks. What made it possible for me to enjoy such a paddle was the Franklin Falls Flood Control Project built by the U.S. Army Corps of Engineers between 1939 and 1943, and the Eastman Falls Hydro Dam 1.5 miles downriver of Franklin Falls Dam. This plaque at the USACE's Ledgeview Outlook provides an aerial view (looking upriver) and describes the project's purpose...
According to the USACE the Franklin Falls Dam is designed to hold back the river only during times of flooding, and can hold back as much as 50 billion gallons within its 3,683 acres. However, in normal times the only backed up water is created by the backwaters of the Eastman Falls Hydro Dam, which requires a pool to generate power. This permanent pool covers 440 acres with a maximum depth of 7 feet and provides steady flow to Eastman Falls Hydro which is rated low impact and operates in run-of-river mode.

Thanks to most signs of civilization having been removed 80 + years ago, the area I paddled through had a wilderness feel. Homes, a cemetery, and nine miles of Route 3A were moved to higher ground away from the river. A railroad line was completely removed as well. According to an article by Harry A. Frye in the Boston and Maine Railroad Historical Society's B and M Bulletin (Summer 1978) the railroad line was built in 1847 and hugged the Pemi's west bank for the 12.8 miles between Franklin and Bristol, NH. The article notes the branch having been placed out of service in 1936.
Upon reaching the spot where the village of Hill was formerly located I came across this manmade structure sitting in the middle of the river...
In the late 1800s it was the center support for a covered bridge connecting the communities of Sanbornton and Hill. My guess is that the tree limb sitting atop it attests to just how high the water level has backed up on occasion.
Just a little further up, Needle Shop Brook entered the river...

At Sumner Island, where the influence of Eastman Falls Dam begins to fade, the current was noted to be much quicker and I began to see good-sized rocks just beneath the surface. Turned about there and paddled back down to Shaw Cove having not seen or heard another person all morning.
I walked a short distance from the marker to a set of parallel bridges carrying Rt. 3A and the Pemigewasset Valley Railroad over the Asquamchumauke River. The view from the bridge looking upriver...
