Lagoon Fencing Requirements

Whether a fence is required, and what kind, depends on where you live. This guide does not state any requirement; it explains who decides and what to ask.

Why does fencing matter around a lagoon?

A fence keeps children, visitors and animals from reaching the edge, where falls can have terrible consequences. It also marks a boundary so that everyone knows the area is off limits.

A fence is only one layer of protection. Gates, locks, signs, training and supervision work together with it.

Fences should make it difficult for a small child to get in, not just a deterrent for adults. Think about the youngest and most curious visitor to your farm. Consider that a fence can create a false sense of security if gates are often open. The fence helps only when it is kept closed and in repair.

• Keeps people and animals back.
• Marks a clear boundary.
• Works best with other measures.

Who sets the fencing rules?

Rules about lagoons come from state environmental and agriculture agencies, sometimes counties, and may come with permits or program requirements. Requirements may differ for new and existing lagoons and for different sizes and types of operation.

This article does not state what your location requires. Contact your state agency, your conservation district or NRCS office, and your county. Ask them to put the answer in writing.

Agencies may update rules over time. Ask when the guidance was last updated, and check again before making changes. If you plan to buy land with a lagoon, ask the seller and the state agency about its permit and fencing history before you commit.

• Ask your state agency.
• Ask your conservation district or NRCS office.
• Get answers in writing.

What questions should you ask?

Ask whether fencing is required for your lagoon, what the fence must do, whether there are rules on gates and signs, and who inspects. Ask whether any standards apply to funded projects.

Ask about the connection to permits and plans for your operation. If you are building or changing a lagoon, ask before you begin.

Write your questions down before you call. Having a list makes the conversation easier and ensures nothing is missed. Ask whether any inspections or reports are due, and keep copies of paperwork where you can find it.

• Is fencing required for my lagoon?
• What gate, sign and inspection rules apply?
• Do funding programs have extra standards?

What makes a fence effective in practice?

Beyond the rule, consider how children and animals could get past a fence. Check for gaps, low spots, climbable features and gates that are left open. Consider the terrain and the surrounding area.

Ask your extension office about designs used locally, and use the standards that officials give you rather than guesses.

Check that the fence also keeps livestock away from banks, since animals can cause damage that makes a lagoon edge unstable. Ask neighbors who have lagoons what they learned from agency visits, though the agency's answer is the one that counts.

• Look for gaps and climbable features.
• Keep gates latched.
• Use official standards.

How should you maintain the fence?

Walk the fence regularly and after storms, mowing and heavy equipment work. Repair gaps, damaged posts and loose wire at once. Keep vegetation from hiding damage or making it climbable.

Keep a log of inspections and repairs. A written record helps show diligence and reminds everyone to follow up.

Mark gates with the instruction to keep them closed and latched, and ensure that nobody props them open for convenience.

• Inspect on a schedule.
• Repair damage at once.
• Keep a written log.

Do signs and training matter too?

Yes. Signs warn visitors who do not know the farm, and training makes sure workers understand why the rule exists. Brief new workers and visitors on arrival, in a language they understand.

For employer duties, see OSHA's agriculture page. For youth work rules, confirm with the U.S. Department of Labor.

Review signs yearly. Sun, weather and dirt can make them unreadable.

• Post clear warning signs.
• Train workers on arrival.
• Check employer duties with OSHA.

What if someone gets past the fence?

If a person or animal enters the lagoon, call 911 and give a clear location. Do not enter or reach into the lagoon. This article does not give rescue steps. Trained responders must handle the situation.

After any incident, review what failed and improve it. Support family members and workers who were affected.

After any near miss, talk with the household and workers about what made the lapse possible, and fix the cause. Remember that a rule from one state or program does not carry over to another, so check again if you move or change programs.
