Swimming across a strong current

The first step is to make doubly sure there isn't already a bridge, or a common place people already cross at. No sense in getting wet or risking anything if there is an easier, or proper crossing, a few hundred yards up or downstream.

The other first step is to make sure you are all safe when you cross. Bring a strong rope that is long enough to span the river, or to at least span to a spot midway where you can take a break. A hundred foot rope strong enough for this purpose should be fine for most typical back country adventures. You can then tie the rope securely to the first person crossing, and hang on to that as a safety device in case the crosser wipes out and loses control. Learn the proper techniques for the ad-hoc harness. The rope also comes in very handy in hauling backpacks or other gear across the river. Once someone makes it across.

If the river is not violent, and the danger of falling in is simply that you get wet, have to swim to the other side, then bushwhack through some dense mosquito infested brush to get back to the trail, then you should not use the rope. Use the rope where the danger of falling into the drink is very serious, e.g. a waterfall is not far ahead.

As for where to cross, I disagree with Aaron's answer to target a deeper spot. Shallower is better*. Deeper being slower depends on the width of the stream being constant, which isn't always true. Additionally, the force you feel in a deeper section will be greater, and will be higher up on your body, making it more difficult for you to balance. If it's shallower, and you can see the bottom, you're pretty much in the clear as long as you don't rush yourself.

When you cross, walk across, slowly and carefully. Contrary to Aaron's answer, don't swim across, walk. You can put your feet down. However, the dangers of getting a foot stuck, as he mentions, are very real and very serious. If you maintain your balance as you walk across, you will be fine.

If you lose your balance, immediately pull your feet up, and position yourself flat on your back with your feet in front of you, up high. If the river is violent, your friends can haul you in using the rope. If the river is gentle but strong, then float down in the described position, and paddle yourself to one side or the other, and get out. There is no real technique as far as I am aware, just doggy paddle. Resist the temptation to try and put your feet down to stop you from floating downriver. If the river is deep and fast-moving enough to make this whole ordeal concerning, it is fast enough that if your foot gets stuck you will not be coming back up alive.

Afterwards, collect all your gear, dry yourself off, and continue onward.

*This answer based on the assumption that the river is not very deep, and where 'shallow' is not any deeper than waist height.

I would avoid swimming across if possible. For fording the stream, find a wide and shallow section. If you have a group of people, interlock arms and walk across together with the line of the group being parallel to the stream. This gives each person stability up/down stream, which is the direction you are more likely to fall due to the push of the water.

To cross alone, use a long pole that you can stick into the ground downstream from you. You and the pole become a triangle such that you can lean on the pole to offset the downstream push of the water. Move only one of your feet or the pole at one time.

That all said, sometimes you can't cross. Many years ago, I was on the North Cascades and had gotten dropped off at a trailhead. The plan was to hike over a mountain range and back to camp on the other side, something like 10-12 miles if I remember right. There was a sign near the trailhead saying that the "Panther Creek bridge was out". It was a nice summer day, so I figured I'll just get a bit wet. When I got to Panther Creek, I found it was a lot more than what we call a "creek" around here. It was a swift flowing small river, probably 5 feet deep or so in the middle and maybe 50 feet across. I tried to ford it, but it got too dangerous, and I could see once I got swept off my feet I'd be carried quite a ways downstream before I could eventually make it to one bank or the other and grab hold of something. It was a long walk back to camp along the road.

As a side note, on the long hike back to camp along the road, there were several scenic turnouts. At one such turnout a crowd of people had gathered around a car. When I got closer, I could see they were all listening to the radio in that car, which had been turned up loudly for the purpose. I got there just in time to hear the voice of Richard Nixon say "is abhorrent to every instinct in my body". Yes, it was late afternoon (in Washington state) on 8 August 1974.

Crossing a stream in a group

Each participant will bring their own rope to the trip if such a crossing is anticipated.

First picture: #1 will tie the rope around him. Strongest will cross first. #2 and #3 will not be tied to the rope but they'll simply handle the rope and prevents the crossing person from washing away downstream.

Second picture: When #1 reaches the other side, #1 detaches himself from the rope. #2 attaches himself and crosses the stream.

Third pricture: When #2 has reached the other side, #2 detaches himself, #3 attaches himself and crosses the stream.

From my experiences with white water rafting, It is actually far safer to cross at a deep point where the current will be slower even if you are with someone who is not a particularly strong swimmer. You never want to be able to place your feet down for the risk that a foot will get stuck and the current will force you under. The water is strong enough that even if you are wearing a PFD, you may drown only inches from the surface. The best advice I can give you is to plan ahead to bring PFD's and know where you will be crossing.

Practice swimming at a local pool regularly, so that you know your capacity, strength, endurance, and technique.

If you swim across a river, you can swim diagonal to the current in an attempt to offset the push downstream. A big part of swimming across rivers is psychological: accept that you are going to go downstream to some extent, no matter how strong a swimmer you are, and if you surrender to this fact the whole experience is much more relaxed.
