Sebago to the Sea on Stand-Up Paddleboards

Since getting two stand-up paddleboards this spring, the idea of paddling the Presumpscot River from Sebago Lake to the sea occupied a space in my mind. It was an itch that needed to be scratched. So at 6:00 a.m. on a crystal clear July morning I found myself with 6 friends scurrying across Route 35 in Windham, Maine with inflatable SUP in hand. We chose to launch in the Eel Weir Canal, a flat water canal that connects Sebago Lake Basin to the the Presumpscot. This allowed us to do an end run around the unrunnable whitewater that makes up the first mile or so of the Presumpscot River.

It’s roughly 25 miles on the Presumpscot River from Sebago Lake Basin to tidewater. It involves 9 portages around 8 dams and one waterfall. Presumpscot means “many falls” in the Abanaki language. Unfortunately, most of these falls are under either dams or the slow water impoundments created by the dams. Despite these impediments, the river can feel remote and wild……….much of the time it’s hard to tell you’re close to the largest city in Maine.

Heading in I had no idea how long it would take to pull this trip off.  There was a good current but also plenty of slow-moving water. Soon it became apparent we would have plenty of time as we covered the first few miles with ease. The portages were anywhere from a quarter mile to three-quarter mile in length, which by the end of the day adds up to a lot of SUP hauling. All were well-marked and easy to follow except one. More on that later. It helped that I scouted the portages ahead of time to avoid snafus on paddling day.

We made our way through Windham and Gorham, finally arriving in Westbrook. This is where it got a little interesting. The first Westbrook portage was the Saccarappa Dam (or as I like to call it, Sack-a-Crappa). This was a half mile right through lovely downtown Westbrook. The way people were looking at us you’d think nobody had ever walked through town carrying SUPs before. Well, come to think of it, they probably hadn’t. We stopped for some very mediocre Mexican food and a voluminous 27 oz. beer that was included with the tacos. In fact, I’m sure the beer’s main intent was to take our attention off the lousy tacos.

A short paddle through Westbrook brought us to the mother of all portages: Sappi’s Cumberland Mills Dam, a solid three-quarter mile slog on pavement and then a bushwhack through a small jungle. I had visited it a few days earlier and talked to the gentleman in the guard booth, who confidently assured me the portage was “over there.” They even had it indicated on a map. In hindsight, it was the confidence of a man well-versed in the art of bullshitting unsuspecting visitors. Since it was pouring rain I didn’t bother looking too closely, figuring if they had it on a map then it had to be a good portage. When we had to do it for real, however, it proved to be an almost impenetrable thicket of thorns and dense underbrush. After crashing through quagmire of bushes and mud, the final put-in required an otter slide down a steep bank and into the water. Other than the strainers (potentially deadly trees or fallen branches that can trap a paddler) lining the river, it was now a clear run in to Presumpscot Falls, the last portage.

Once below Presumpscot Falls we were in tidewater, making the trip official. Total time was about 11 hours, although we paddled quite leisurely and took a nice long lunch. I bet we could take it down to 8 hours or so with some serious paddling and no lousy tacos. We’ll bring our own beer next time.



SKILL LEVEL/EXPERIENCE: If you are thinking about doing this trip, keep the following in mind. Advanced skills in stand-up paddle boarding are not an absolute requirement. You should, however, at the least be competent in handling a canoe or kayak in moving water. This means being able to avoid obstacles like rocks and submerged tress, avoiding strainers, maneuvering in the occasional bit of fast water and knowing the basic paddle strokes. You should also be reasonably fit as it involves a long day on your feet and a few miles of carrying your board and gear over some rough portages. If you’re a couch potato more accustomed to grabbing a bag of chips than a paddle, you might want to work your way up to a trip like this.

GEAR: With so many portages it was essential to go light. I carried a small dry bag with food, water and a little extra clothing. Westbrook was the first convenient re-stocking spot but that was about 75% into the trip so bringing plenty of food and water was essential. Rounding out the kit was a lightweight PFD (NRS Ninja, PFDs are required by law) and a Werner Carve SUP paddle. A couple guys used inflatable PFDs—the NRS Big Kahuna—which are even lighter. My SUP is an NRS Earl 4 inflatable, weighing in at only 21 lb. Inflatables are certainly not the fastest boards in the world but with the potential of rough portages on rocks I didn’t want to take the chance of smashing my nice touring SUP. The Earl is tough and can easily handle a few bounces off rocks and hard beachings. Water level was high for mid-July so the current easily negated the inherent slowness of an inflatable SUP. Finally, we all wore shoes or sandals that were comfortable to walk in. I like to paddle barefoot but I brought along a pair of closed-toe Keen sandals for the portages.




  1. Nice start to the blog Tom. I did a similar trip on the Mousam River years ago in a kayak. There were just about the same number of portages mostly due to dams. I’m interested in where you take this blog.
