White Water Rafting on the Kennebec River

Posted September 09, 2009 10:50 AM by baumah

After a 45-minute bus ride to the beginning of Maine's Kennebec River, we got in line for a raft and a guide. The Kennbec, our tour guide told us, is ordinarily characterized by flows of 4,500 cubic feet per second (CFS). Because of all the rain that fell this summer, however, the 150-mile river was now flowing at about 8,600 CFS. This meant larger, faster-flowing rapids for my first whitewater rafting trip.

What is White Water Rafting?

As a sport, white water rafting has been popular since the mid 1970s. It involves navigating an inflatable raft made of multi-layered rubberized or vinyl fabrics down rivers of varying degrees of difficulty. Rivers are rated by the level of skill required for navigation. Class 1 is the easiest and Class 6 is basically un-runnable. The rapids at the Kennebec River are rated at Class 3 and Class 4. Because of the conditions we faced, however, our guide said the waters would be better than most Class 4 rapids.

In white water rafting, hydraulics are areas where water has been affected by a rock, ledge or other object in the river so that the water runs into the object and then rolls back on itself. These formations are often known as "holes" because they can trap a person, kayak, or even a raft full of people. One of the more exciting maneuvers in rafting is when a raft paddles through a hydraulic with enough momentum to push right through.

The Adventure Begins

As our group set the raft in the water and pushed off, I wondered how big the rapids would be - and could I fall out of the boat? As we paddled into the first set of rapids, the waters of the Kennebec looked pretty rough. Yet the boat seemed to push through the waves without any problems.

After successfully navigating the first few rapids, our guide let us know that the next set of rapids contained a hydraulic named "Maytag" that was usable be only when the Kennebec featured at least 8,000 CFS of water. Luckily for us, the heavy summer rains provided more than enough flow.

Our guide then reminded us that we needed to follow her instructions exactly, and that we would need to hold on tighter than normal to get through.

When we first saw Maytag, the hydraulic seemed to be not much larger than the other rapids we had navigated. As we came closer, however, we began to notice a hole in the water and a big wall right in front of it. Our guide shouted at us to row. When we were a few feet away, I grabbed onto a rope in the raft and held on as tightly as I could.

Toes and Nose Up

Our raft's front-end plowed into the wall of water and launched three people, myself included, into the Kennbec River. As the realization that I had just been thrown out of the raft sunk in, I tried to get back onboard as quickly as I could. The other two rafters who had fallen out of the boat were quickly pulled in. But as I struggled to approach the boat, I noticed the rafters' efforts had changed from trying to pull me in to trying to navigate through the rest of the rapids since I was now too far away.

Realizing that I would probably remain in the water through the rapids with just my life jacket on, I remembered the safety instructions I had been taught - "toes up and nose up".. Floating on my back while keeping my face and feet above the water would keep me from getting caught on anything below the surface.

After spending a couple of minutes that seemed like hours in the water, I was able to reach calmer waters and get back on the boat. My life jacket had deserved its name 100%.

One of my favorite pastimes... however I generally like a bit calmer water... And I must have my fishing pole handy.

I remember white water rafting in Girl Scouts many years ago, although it wasn't so rough. It was more like don't get caught on the rocks while going down a river. We hit a rock and I flew overboard. It was so fun. I waved to my peeps watching me from the raft before I realized that I should do the dead man's float before I hit something and get hurt.

My senior year in high school we did more white water rafting and that was so enjoyable. We even purposely flipped the raft by going against the current, which was thoroughly exhausting, but really enjoyable. There was even a point in the river which you could jump off of a tall rock into the river. The experience was very good and I wish that I had the chance to do it again.

I've only gone White Water Rafting once and would love to do it again. I floated the Gauley River in West Virginia. It was a 2 day trip the first day had everything from class 1 to a high 4 maybe even a 5. The second day was calm play in the water conditions.

I often pull out the video tape that was made for us by the companies Kayakers that floated with us as both a safety precaution and to take the video. Looking at your pictures you were in a strictly paddle controlled boat. We had both paddle & oar controlled in our group. The Guide had much more control if they were in the an oar boat. There was even a hole called Guide's Revenge. The theory was the guide would hit the hole just right and dump all the passengers out while they stayed in the boat. Our guide made a slight miss calculation he ended up in the water with only about half of the passengers. Maybe some day I'll get to do this again.

Hey, that sounds like you had a great time. This coming weekend a bunch of us are going up to the Kennebec, though the only difference is the dam up river is conducting a turbine release of water, so that the rapids are Class 4-5. Just by the pictures it looks like fun.

I've been rafting on the upper Hudson River. It is truly a thrilling adventure, especially if the water is high.

I have also been to the kenebec for flyfishing reasons many many times. It has to be one of my top five favorite rivers. It is full of great pockets and hydrolics as well as very clean water. Glad you enjoyed it.

Bob
