American Whitewater Accident Report - January - July 2025

4. The current is carrying you into a sweeper. Good luck. Pray. Some advocate switching into a traditional stomach-down, head-forward swimming posture, and then trying to launch-up your belly onto the sweeper trunk. I've never been in this situation and never want to.
I thought the standard "last resort" recommendation is to swim aggressively directly towards the strainer to build momentum to give you a better chance of getting on top of it. Is there a different school of thought?

 
When I was 60 years old, I signed up for a Swift Water Rescue Technician certification course given by NYS Homeland Security. Before being allowed in the program, all had to demonstrate we could flat water swim 400m using various designated strokes without stopping. The facility in central NYS was designed and built by the same organization that builds Olympic whitewater courses. Ours is capable of discharging and recycling 100,000 gal/min. Not only do we swim aggressively, learning rescue techniques, we also learn to control rescue rafts, and even canoes and kayaks. Included is a simulated low head dam, and a city scape with flooded buildings with furniture, and flooded vehicles for rescue training. We were taught to avoid strainers, if possible, but otherwise to swim aggressively toward it, fast enough to launch yourself over the top. Of course, we only used smooth inflatable strainers, lacking any upward pointed branches.

After Swift Water certification, I went on the next winter to train on a frozen lake for cold water ice rescue training.

Following that, I certified in a steep sided white water canyon as a swift water rescue motor boat operator.
I had a tremendous amount of fun in each of these, as well as learning valuable rescue skills for myself and others.



Although I am primarily a flat water canoer, one never knows when a race might have a segment including some class 1 or 2+ swift water, or the weather on a large. wide body might kick up some nasty stuff. There are two short segments on the Yukon River where such knowledge could be useful where it is common for some racers to capsize on almost every race.

I meant the same thing.

Last ditch: go into a forward crawl swimming posture, swim aggressively at the sweeper for momentum, and then try to launch your torso up onto the sweeper/strainer high enough so that the current doesn't pendulum-drag your legs under it. This theoretically should give you a better chance of surviving the sweeper than hitting it in a defensive posture on your back with feet downstream. However, I've never seen it done—and if it can be done, it surely would take a huge amount of energy and technique from a swimmer with significant upper body strength.

Avoiding sweepers is the best deterrent. That takes river experience, river condition judgment, and scouting whenever possible. On blind corners, paddle on the inside of the turn where the water is shallower, the current is slower and the probability of sweepers much lower, using a back ferry or other highly practiced inside-corner-hugging technique.

That is exactly what the rescue training course taught us. I can say that it does work for. a smooth top inflatable "strainer" durijng the training. although many different get legs caught in the current under and got sucked down and under into the unknown.
