Irrigation Canal Safety

Canals are built to move water, and that movement is what makes them dangerous. This guide explains the hazard in plain terms and points to the official bodies that know your local system.

Why are irrigation canals dangerous?

A canal can seem harmless, especially when it looks shallow. But moving water can pull a person off balance, and the sides are often steep, smooth and hard to climb. Cold water and heavy clothing can make things worse.

Canal flow can also change without warning when gates are opened or water is released upstream. A spot that is calm in the morning may be different by afternoon. Do not trust appearances.

• Moving water can overpower even strong swimmers.
• Steep, smooth sides make exit difficult.
• Flow can change when upstream gates open.

Who manages the canal near you?

Many canals belong to irrigation districts, ditch companies or other organizations, and they have their own rules about access and use. Find out who manages the canal near your farm and how to reach them.

That organization can tell you about release schedules, closures and safety rules for your area. Do not enter canal rights-of-way or work on structures without the manager's permission. Rules vary by state and by district, so ask rather than assume.

• Save the district's contact number in your phone.
• Ask how you will be notified of flow changes.
• Never operate gates or structures that are not yours.

How do you keep children away from canals?

Children are often drawn to water, and canals running beside fields and homes are easy to reach. Set a firm family rule that canals are not for play, and explain it in language children can understand. Repeat it often, especially for visitors.

Supervision matters most. Young children need an adult close by whenever water is nearby. Fencing or other barriers may help where canals run close to the house or yard; ask your canal manager and county about what is allowed and recommended.

• Make the rule simple and consistent.
• Supervise young children close at hand around any water.
• Talk to neighbors and visiting families about the rule.

What should workers know before working near a canal?

Workers who must be near canals, for example to check a headgate or remove debris, should have training from the canal manager or the employer. Avoid working alone, and let someone know where you are and when you will be back.

Do not attempt to retrieve equipment or animals from fast water on your own. A task that seems quick can turn dangerous in seconds. Ask your employer, canal manager or safety trainer about approved methods. OSHA's agriculture pages are a good starting point for employer responsibilities.

• Use a check-in system when working alone near water.
• Avoid shortcuts such as walking along wet banks.
• Follow district and employer procedures, not guesses.

What should you do if someone falls in?

Call 911 right away and give the exact location. Do not enter moving water to attempt a rescue. Rescue in moving water is specialized work, and well-meaning bystanders have been hurt. This article does not give rescue techniques, and you should not improvise them.

Stay safe on the bank, keep your eyes on the person if you can do so safely, and follow the instructions of the dispatcher. Training in water safety and first aid, offered by groups such as the American Red Cross, prepares people to act correctly.

How can you prepare before irrigation season?

Before the season begins, walk the canal sections near your property and look for gaps in fencing, missing signs and eroded banks. Report problems to the canal manager.

Hold a short family or crew meeting. Review the rules, the phone numbers and who to call. Add the canal manager's number beside your emergency contacts. Preparation takes little time and can make a real difference.

What are common mistakes to avoid near canals?

One common mistake is treating a canal as a shortcut, a place to cool off or a spot to retrieve something that fell in. Another is assuming that a flow you saw last week is the flow you will see today.

A third is leaving rules unspoken. Neighbors, relatives and new workers may not know what you know. Say the rules out loud, and put them in writing where they can be seen. Layered measures such as fences, signs, supervision and communication with the canal manager work better than any single one.

• Do not use canals for swimming or shortcuts.
• Never assume the flow is unchanged.
