“As ponds start to get low on water, the cattle are sourcing the water from a smaller access point, and so it is important to monitor them,” said K-State veterinarian Brian Lubbers.
He added that there are increased health risks when cattle are drinking from a depleted water source that is hard to get to.
“As ponds shrink, accessibility to the water can be an issue depending on the shape of the pond,” Lubbers said. “Deep ponds can have steep sides that make it difficult for the cattle to reach and leave the water source.”
Also as the pond water becomes stagnant, the quality goes down, White said.
“As the water amount decreases, there is more fecal contamination coming from cattle trying to get to the available water,” Lubbers said.
Once ponds are no longer viable watering options, it is time to look for other solutions, say the experts.
“A temporary solution is to haul water in tanks to the pastures where the cattle are,” K-State nutritionist Phillip Lancaster said.
He added that it is critical that the water tank only be used for storing water and that no amount of rinsing will fully clear the chemicals from a tank that was used for something else prior to hauling water.
“The plastic polymers in the tank may hold onto the nitrates and you cannot dilute them enough through rinsing to be sure that it won’t kill cattle,” Lancaster said.
White agreed, adding: “If the tank has been used for something besides water, it is no longer a viable option for water.”
Another solution to a possible pond dry-up is to look at the grazing rotation of the herd, Lancaster said.
“Producers may need to graze a pasture with the pond earlier in the season to use that water source first, and then rotate cattle to other pastures that either have other water sources or are easier to haul water to,” he said.
