What are Main Navigation Errors People Make Along Rivers?

Failing to Account for Water Levels

When navigating rivers, it’s crucial to consider the current water level. This can greatly affect the depth and speed of the water. A 1-foot (30 cm) difference in water level can increase the river’s velocity by as much as 50%. Failing to account for this can result in underestimating the risk of swamping or being swept away by strong currents. When possible, take water level readings at multiple points along the river to get an accurate idea of the situation.

Misjudging Current Speed

River currents can be particularly unpredictable, and it’s essential to assess their speed accurately. One method is to use a current meter or a makeshift device, such as a floating stick or a plastic bottle, to gauge the water’s speed. Another approach is to observe the movement of natural objects like sticks or leaves, which can indicate the flow rate.

Overreliance on Visual Cues

Relying on visual cues alone can be misleading when it comes to river navigation. For example, a river may appear calm and peaceful from a distance, only to reveal strong currents and obstacles upon closer inspection. To avoid this, use a combination of observations, measurements, and experience to accurately assess the river’s conditions. Always prioritize caution and seek additional information before proceeding.
