Quick Answer
To signal for help while on a river, create a visible fire, use a whistle or other loud noise-making device, and create a smoke signal during the day. A mirror or shiny object can also be used to reflect sunlight towards any potential rescuers.
Creating a Visible Fire
A fire is one of the most effective ways to signal for help while on a river. To create a fire, start by gathering dry tinder and kindling. Once you have a small flame, add larger logs to build a fire that can be seen from a distance. Aim for a fire that is at least 3 feet tall and has a diameter of 1-2 feet. A fire can be seen from up to 20 miles away, depending on the terrain and weather conditions.
Making a Loud Noise
A whistle is a simple and effective way to signal for help while on a river. The International Distress Signal is three short blasts of a whistle, followed by a pause, and then three more blasts. This signal can be heard from up to 5 miles away. If you don’t have a whistle, you can use any other loud noise-making device, such as a horn or a bell.
Using a Smoke Signal
A smoke signal is another effective way to signal for help while on a river. To create a smoke signal, build a fire that is designed to produce a large amount of smoke. This can be done by burning damp wood or other materials that produce a lot of smoke. Aim for a smoke signal that is at least 10 feet above the water and can be seen from a distance. A smoke signal can be seen from up to 20 miles away, depending on the terrain and weather conditions.
