How to record a whitewater run with GPS

Prepare the phone before rigging

Charge the device, confirm available storage, and enable the permissions needed for location recording. Download any information you may need where service is thin. A cold battery can drain faster, so keep the phone warm when conditions demand it.

Use a waterproof, impact-resistant case and secure the device inside the boat or on your body where it cannot create an entanglement hazard. A phone is not a substitute for river communication, navigation, rescue equipment, or a plan that works without service.

Start with a clear location signal

At the put-in, give the device a clear view of the sky when practical. Open the correct river section and verify that the GPS indicator has settled before starting. Record the vessel, crew, and any pre-run notes while hands are still dry.

Start recording close to launch, then stow the phone. Do not delay the group in an exposed access area or handle the device in current.

Let the recorder work in the background

River People can capture route, distance, duration, notes, vessels, skills, media, and gauge levels for a run log. GPS samples may drift under cliffs, tree cover, bridges, or inside a bag. Short gaps and imperfect lines are normal limitations, not proof of an exact path.

Keep attention on paddling and the group. If recording conflicts with safety, ignore the recorder. A missing track is preferable to a distracted decision.

Stop at a safe take-out location

After the group and equipment are secure, stop the recording and confirm the intended section. Remove obvious approach or shuttle movement if the product offers editing, and add notes about flow, weather, hazards, access, and the character of the run while details are fresh.

Check whether the duration includes breaks and whether the distance is plausible. Track values are estimates influenced by hardware, sampling, terrain, and signal quality.

Create notes your future self can use

• Record the observation source, value, unit, and time rather than only "good level."
• Describe hazards with a location, date, and direction of travel.
• Note access or shuttle changes that affected the day.
• Separate objective observations from personal impressions.
• Use skill notes as a reflection, not a universal claim about the rapid.

Protect crew and location privacy

Ask before naming or publishing other paddlers. Review photos and tracks for home addresses, private access, sensitive cultural sites, rescue activity, or locations that should not be broadly shared. Keep private notes private.

A recorded track shows where one device traveled on one occasion. It is not a recommended line, a route guarantee, or evidence that a section is currently open or safe.
