Fishing safety: life jackets, cold water, lightning and rising rivers

The Wet That Line team · Updated October 10, 2026

Most fishing trips are quiet. The few that go wrong usually come down to the same handful of things, and the agencies that track them publish simple rules for each.

Wear a life jacket

Wear one on a boat or kayak. The U.S. Coast Guard reports that most people who drown in boating accidents were not wearing a life jacket. A life jacket only helps if it’s on you; there’s rarely time to put one on after something goes wrong.

Cold water: the 1-10-1 rule

Falling into cold water can trigger a gasping “cold shock” response. The National Center for Cold Water Safety sums up what happens next with a rough rule of thumb, 1-10-1. The times are approximate warnings, not a timeline to count on:

About 1 minute to get your breathing under control.

About 10 minutes of useful movement.

About 1 hour before hypothermia makes you lose consciousness.

Lightning

“When thunder roars, go indoors” (National Weather Service). Get off the water at the first thunder. A long rod does not make you any safer.

Rivers that rise fast

Rivers can rise quickly after rain or a dam release, even under clear skies. USGS stream gauges report real-time flow and water level; rising, high or fast water makes wading dangerous. Where a USGS gauge is nearby, Wet That Line shows its readings (flow, and water temperature where the gauge measures it) in a spot’s conditions. A gauge up- or downstream may not match the water in front of you, so look at the river itself before you step in.

Tell someone

Let someone know where you’re going and when you’ll be back, especially at remote water with no signal. Before you lose service, you can save a map area for offline use in Wet That Line.

Frequently asked questions

What is the 1-10-1 rule?

From the National Center for Cold Water Safety: after falling into cold water, you have about 1 minute to get your breathing under control, about 10 minutes of useful movement, and about 1 hour before hypothermia makes you lose consciousness. The times are rough warnings, not a dependable survival timeline.

When should I get off the water for lightning?

At the first thunder. The National Weather Service says: when thunder roars, go indoors. A long fishing rod does not make you safer.

How do I know if a river is rising?

USGS stream gauges report real-time flow and water level. Rivers can rise fast after rain or dam releases; rising, high or fast water makes wading dangerous.
