6 Best Water Trough Covers For Predator Protection

You walk out to the barn at dawn and see it: muddy paw prints all over the edge of the stock tank, with feathers or worse floating in the water. It’s a clear sign that a predator was here last night, using your livestock’s water source as their personal drinking fountain or, more grimly, a wash basin. Securing your water trough isn’t just about animal safety; it’s about making your farm a less attractive target for unwanted visitors. A good cover protects your water quality, your time, and your animals.

Why Predator-Proofing Your Trough is Crucial

An open water trough is a massive invitation. To a coyote, raccoon, or fox, it’s a reliable water source that tells them this is a good place to hang around. They come for a drink, and they stay to scout for a meal—your chickens, your ducks, or even your young lambs. By securing the trough, you remove a key resource, encouraging them to move on to easier territory.

Beyond predators, a cover is a critical safety feature for your own animals. We’ve all heard horror stories of ducklings, chicks, or even barn kittens falling into a stock tank and being unable to get out. A secure cover completely eliminates this heartbreaking risk. It turns your trough from a potential hazard into a safe, reliable water station.

Let’s not forget the practical benefits. A covered trough stays dramatically cleaner. It keeps out falling leaves, windblown dirt, and stirred-up bedding, which means the water stays fresh longer. By blocking sunlight, a cover also significantly reduces algae growth, saving you the constant chore of scrubbing green slime. You’ll spend less time cleaning and more time on other farm tasks.

Key Features of a Secure Water Trough Cover

The most important feature is weight and a secure fit. A flimsy piece of sheet metal or a loose plank of wood is a joke to a determined raccoon. The cover needs to be heavy enough to resist being pushed aside or have a reliable latching mechanism. Think less "lid" and more "barrier."

Material choice dictates longevity and effectiveness.

• Galvanized Steel: The gold standard for durability. It’s chew-proof, rust-resistant, and heavy.
• Heavy-Duty Polyethylene: Excellent for modern poly tanks. It’s lighter than steel but tough enough for most predators and won’t rust.
• Wood: A great DIY option, but it must be exterior-grade and sealed with an animal-safe product to prevent rot. It requires more upkeep.

Finally, consider your own access. A cover that’s a fortress against predators but a ten-minute ordeal for you to open is not a sustainable solution. The best designs are hinged or have a smaller, built-in access door. This allows you to check water levels, clean, and refill without having to wrestle with a heavy, cumbersome lid every single day.

Tarter Galvanized Stock Tank Cover for Durability

When you need a solution that just works, the Tarter galvanized cover is hard to beat. These are specifically designed to fit Tarter’s own line of steel stock tanks, ensuring a perfect, no-gap fit that leaves no edge for a predator to pry up. It’s a purpose-built system, and that precision is its greatest strength.

The sheer durability of galvanized steel is the main selling point. It can handle the weight of a curious coyote, the claws of a raccoon, and won’t degrade under years of intense sun or winter ice. This is a buy-it-once solution. Its weight alone is a significant deterrent, sending a clear message to wildlife that this water source is closed for business.

The primary tradeoff is its specificity. This cover is not a universal solution; it’s made for Tarter tanks. If you have a different brand, you’re better off looking elsewhere. It’s also an investment, but when you factor in the time saved on cleaning and the peace of mind it provides, the cost becomes much more reasonable.

High Country Plastics Insulated Water Tank Lid

High Country Plastics offers a lid that solves two problems in one, making it a brilliant choice for farms in variable climates. Their covers are designed for their insulated tanks, providing a complete system to keep water from freezing in the winter and keep it cool and palatable during summer heat waves. This dual function is its standout feature.

From a security perspective, the heavy-duty molded plastic is more than sufficient for common farm predators. The lids are designed for a snug, overlapping fit that frustrates prying paws and noses. While a determined bear could likely get through, it will stop raccoons, skunks, and opossums in their tracks.

The decision to choose this lid hinges on your climate. If you regularly deal with frozen water troughs, the combined value of insulation and protection is immense. However, if you live in a mild climate where freezing is never an issue, you may be paying a premium for a feature you don’t need. It’s an excellent, efficient system for the right environment.

Behlen Country Poly Cover for Versatile Use

Behlen’s poly covers are a fantastic all-around option, striking a great balance between durability, weight, and price. Designed to fit their popular poly stock tanks, these covers are much lighter than their steel counterparts, making daily access significantly easier for the farmer. You don’t need to be a weightlifter to check the water.

What sets these covers apart are the thoughtful, practical design elements. Many models come with pre-molded areas for installing float valves or access ports for de-icer cords. This shows an understanding of how farmers actually use their equipment, saving you the hassle of cutting and modifying the lid yourself.

The main consideration here is long-term UV exposure. While the polyethylene is UV-stabilized, it will not last as long as a galvanized steel cover. After a decade or so in direct sun, it may become brittle. That said, for its cost and ease of use, it offers outstanding protection and functionality for the vast majority of hobby farms.

Custom Welded Metal Grate for Heavy Duty Needs

For situations where off-the-shelf won’t do, a custom-welded grate is the ultimate in predator protection. If you have an unusual-sized trough, a concrete tank, or are dealing with persistent, powerful predators like bears, this is your answer. You hire a local welder to build a heavy-gauge steel grid that fits your tank perfectly.

The beauty of this solution is its simplicity and brute strength. Animals can easily drink through the grid, but nothing can get in. The sheer weight of a rebar or angle-iron grate makes it impossible for any predator to move. You can design it to be hinged in the middle for easier access for cleaning.

This is not a cheap or easy option. It requires finding a fabricator and paying for custom work. It will also be extremely heavy. But when you’ve tried everything else and are still finding your troughs compromised, a custom grate is the final, definitive solution that puts an end to the problem for good.

DIY Hinged Plywood Cover for a Custom Solution

For a practical and budget-friendly approach, nothing beats a well-made DIY cover. A sheet of 3/4-inch exterior-grade plywood, a couple of heavy-duty strap hinges, and a solid latch are all you need. This allows you to create a perfectly sized cover for any trough, old or new, metal or plastic.

The key is to go beyond simply laying a board on top. A loose board is a toy for a raccoon. Securely fasten the hinges to one side of the trough and the plywood. On the opposite side, install a hasp and a carabiner clip or a simple barrel bolt. This prevents the cover from being lifted or slid off.

To ensure it lasts, you must protect the wood from the elements. A few coats of animal-safe exterior paint or a deck sealant will prevent water from soaking in and causing the wood to warp and rot. While it requires a bit of weekend work, a properly built plywood cover offers robust protection at a fraction of the cost of commercial options.

Rubbermaid Commercial Lid for Smaller Troughs

Sometimes the most obvious solution is the best one. If you use the ubiquitous Rubbermaid structural foam stock tanks—the black ones seen on nearly every farm—their own branded lids are an excellent choice. They are designed for a perfect, snap-on fit that is surprisingly secure.

While made of plastic, the tight seal and recessed grip make it very difficult for animals to get any purchase to pry it open. It’s an ideal barrier against raccoons who rely on their dexterity to lift and manipulate objects. It also does a fantastic job of keeping hay, chicken feed, and other debris out of the water in a busy barnyard.

This is clearly a solution for smaller-scale needs, typically for troughs 150 gallons and under. It’s not a heavy-duty security system for large cattle troughs or high-pressure predator areas. But for protecting the water for your goats, sheep, or poultry, it’s an affordable, effective, and incredibly simple solution.

Ultimately, the best water trough cover is the one that fits your specific tank, budget, and predator challenges. Whether you choose a durable steel lid, a versatile DIY solution, or a simple plastic cover, the goal is the same: to make your water source secure, clean, and safe. By removing this easy target, you make your entire farm a less appealing place for predators to linger.
