6 Best Livestock Troughs For Hot Summers

It’s the middle of a blazing July afternoon, and the air is thick and still. Your animals are seeking any patch of shade they can find, but their water trough sits baking in the sun. Access to clean, cool water is non-negotiable for livestock health in the summer, directly impacting hydration, heat stress, and overall well-being.

Keeping Water Cool: Summer Trough Essentials

The single biggest challenge in summer isn’t just providing water; it’s providing cool water. A trough full of sun-baked, algae-filled water is barely better than an empty one. Animals will drink less if the water is too warm, leading to dehydration even when water is available.

Location is your first and best tool. Placing a trough in the shade of a large tree or on the north side of a barn can dramatically lower water temperature. If natural shade isn’t an option, a simple lean-to or even a tarp stretched over T-posts can make a world of difference. The goal is to block that intense midday sun.

Material also plays a crucial role. Light-colored poly tanks reflect more sunlight than dark ones, and insulated or partially buried tanks use the ground’s natural coolness to their advantage. Consider the size, too. A larger volume of water heats up more slowly than a small one, but it also needs to be consumed and refreshed before it becomes stagnant.

Tuff Stuff Stock Tank: Classic Durability

When you need a trough that can handle being kicked, bumped, and leaned on, the Tuff Stuff tank is a go-to. Made from a heavy-duty, chemically neutral recycled plastic, it’s flexible enough to resist cracking in temperature extremes. This is the kind of tank you can set up and largely forget about, knowing it will withstand daily abuse from cattle or horses.

The main drawback for summer use is its typical black color, which absorbs heat readily. This makes strategic placement absolutely critical. A Tuff Stuff tank left in the open sun will have bath-warm water by noon. Positioning it in deep shade is essential for summer success.

Despite the heat absorption, its durability makes it a solid choice for high-traffic areas or for animals that are hard on equipment. It’s a simple, effective basin that won’t fail you. Just be prepared to manage its temperature with shade and regular water changes.

Bar-Bar-A Drinker: Automatic, Insulated Pick

For those looking to minimize daily chores and maximize water quality, an automatic waterer like the Bar-Bar-A is a game-changer. This unit connects directly to a water line and only dispenses a small amount of water when an animal presses a paddle. This means the water is always fresh and cool, straight from the underground pipe.

The design is brilliant for summer. Since there’s no standing water, there’s no opportunity for it to heat up in the sun or for algae to grow. It also eliminates water waste from evaporation and keeps pests like mosquitoes from breeding. It’s a closed system that delivers on-demand.

The trade-off is upfront cost and installation. You’ll need to run a water line to your desired location, which can be a significant project. However, for a permanent pasture or paddock, the long-term savings in time, water, and animal health can easily justify the initial investment. This is a solution for efficiency, not portability.

Rubbermaid Trough: Ideal for Portability

Rubbermaid’s structural foam stock tanks are a staple on hobby farms for a reason. They are incredibly tough for their weight, making them perfect for rotational grazing systems or temporary enclosures. You can easily dump, clean, and move one by yourself.

Their portability is their greatest strength. If you’re moving a small flock of sheep or a few goats to a new paddock every few days, you don’t want to be hauling a 50-pound metal tank. The smaller Rubbermaid sizes (50 or 100 gallons) are manageable and fit easily in the back of a utility vehicle.

The downside is that their smaller volume heats up quickly and requires more frequent refilling on hot days. They also lack built-in float valves, so you’re either filling them manually or rigging up your own hose and float system. They are a tool for flexibility, but that flexibility comes with more hands-on management.

Behlen Poly Trough with Integrated Float

The Behlen poly trough with a built-in float system offers a great middle ground between a simple tank and a fully plumbed automatic waterer. You hook up a standard garden hose, and the protected float valve keeps the trough full automatically. This frees you from the chore of topping off the water multiple times a day.

This feature is particularly valuable in the summer when water consumption and evaporation are at their peak. It ensures your animals never run out of water, providing peace of mind if you’re away from the farm for the day. The light color of many Behlen models also helps reflect some sunlight.

The main consideration is the float mechanism itself. While generally reliable, it can be a point of failure. It’s wise to check it regularly to ensure it isn’t stuck or leaking, which could lead to an empty trough or a flooded pasture. It automates the filling, but not the inspection.

Little Giant Trough with Easy-Drain Plug

Cleaning troughs is a constant chore, but it’s especially important in summer when warm water accelerates algae and bacteria growth. The Little Giant series often includes a large, screw-in drain plug that makes this job significantly easier. Instead of siphoning or tipping a heavy, full trough, you can just pull the plug.

This simple feature saves your back and a lot of time. A quick scrub and rinse become a 10-minute task instead of a 30-minute ordeal. For anyone managing multiple troughs for different animal groups, this efficiency is a huge benefit.

These troughs are typically made of durable polyethylene and hold up well, but the drain plug is the star feature. Ensure the threads are clean and sealed properly to avoid slow leaks. It’s a small detail that fundamentally improves the user experience, especially when you need to do a full water change every few days to keep things fresh.

CountyLine Galvanized Tank for Cooler Water

The classic galvanized steel stock tank has an undeserved reputation for getting hot. While the metal itself can get hot to the touch, the water inside often stays cooler than in a black poly tank. The reflective surface of the metal bounces a significant amount of solar radiation away.

Furthermore, the thermal conductivity of metal allows the water to cool down more quickly overnight. A large volume of water in a metal tank, especially if it’s deep, can retain its coolness well into the day. They are also extremely durable and resistant to sun degradation over many years.

The biggest drawback is their weight and potential for rust over time, especially at the seams or if the zinc coating gets scratched. They are best for permanent or semi-permanent locations. For keeping a large volume of water as cool as possible without insulation, a galvanized tank in a shaded spot is a surprisingly effective, old-school solution.

Maintaining Your Trough in High Temperatures

Your choice of trough is only half the battle; summer maintenance is what ensures your animals keep drinking. Algae thrives in sunlight and warm water, fouling the supply and potentially harboring bacteria. You will need to scrub your trough more frequently in July than you do in May.

A stiff brush and a bit of elbow grease are your best tools. Avoid using harsh chemicals that can leave residue. For stubborn algae, a splash of apple cider vinegar can help break it down and offers some health benefits for certain livestock. The key is consistency—a quick scrub every few days is better than a major cleaning every few weeks.

Finally, consider adding a physical element to help cool the water.

• Frozen Jugs: Tossing a few frozen gallon jugs into the trough in the morning can act as giant ice cubes, slowly melting and cooling the water throughout the hottest part of the day.
• Increase Surface Area: A trough that is deeper and narrower will have less surface area exposed to direct sun compared to a wide, shallow one.
• Ensure Fresh Flow: If using a float system, ensuring a steady turnover of water prevents it from becoming stagnant and warm. Even a slow, continuous trickle from a hose can help.

Ultimately, the best trough is the one that fits your system, your animals, and your climate. Whether you prioritize portability for rotational grazing or automated efficiency for a permanent pasture, the goal remains the same: providing a constant source of clean, cool water to keep your livestock healthy and resilient through the summer heat.
