Quick Answer
Warning signs of impending flooding in wilderness areas include sudden changes in water levels, increased water flow, and unusual sounds like roaring or rushing water. Observe changes in water clarity, vegetation, and animal behavior. Look for signs of erosion, like washed-out paths or exposed roots.
Identifying Flood Risks
When navigating wilderness areas, be aware of factors that increase the risk of flooding. These include steep slopes, heavy rainfall, and nearby water sources like rivers, streams, or lakes. A general rule of thumb is to avoid areas with slopes greater than 10% to 15%, as these can lead to rapid water runoff and increased flood risk.
Observing Environmental Cues
Pay attention to changes in the environment that may indicate flooding. These include changes in water levels, increased water flow, and unusual sounds like roaring or rushing water. Observe the color and clarity of the water, as cloudy water may indicate sediment or debris being washed into the water source. Changes in vegetation, such as fallen trees or washed-out underbrush, can also indicate erosion and increased flood risk.
Sheltering in Place
If you suspect flooding is imminent, seek higher ground immediately. Identify nearby shelter options, such as trees with sturdy branches or natural rock formations. When constructing a shelter tree platform, choose a tree with a wide trunk and a flat area at the base. Aim to build your platform at least 10 feet off the ground to avoid floodwaters. Use sturdy branches and rope to create a stable platform, and secure any loose materials to prevent them from being washed away by floodwaters.
