Tips for Assessing Distance to Swim to the Riverbank?

Counting Time to Cross a Known Distance

If you can spot a known distance, such as a 10-meter wide patch of calm water, you can estimate the time it will take to swim across it. To do this, swim at a moderate pace and time yourself for 10-15 seconds. This will give you an estimate of your swimming speed. Multiply this speed by the time it takes to cross the distance you are trying to get to the riverbank. For example, if it takes you 15 seconds to swim 10 meters at a moderate pace, your swimming speed is 0.67 meters per second. Multiply this speed by the time it takes to cross the distance you are trying to get to the riverbank.

Observing the Speed of the Water

You can also gauge the speed of the water by observing the speed at which objects like leaves or small debris move downstream. Hold your hand vertically in the water and observe how quickly the water flows past your palm. If the water flows faster than 1-2 meters per second, it is likely too powerful for you to swim against. In this case, try to swim at an angle against the current to conserve energy or seek a nearby object to grab onto.

Visual Estimation

If you cannot gauge the speed of the water or estimate your swimming speed, try to visually estimate the distance to the riverbank. Look for objects on the riverbank that you can recognize from your initial vantage point. If you see a familiar landmark or object, try to estimate the distance to it and swim in that direction. Keep in mind that your estimate may be off, and it’s always better to err on the side of caution when swimming against the current.
