Livestock water supply must be carefully assessed before implementing rotation grazing plans.
Daily water intake plus evaporation losses may total 20-25 gallons per cow/calf pair during the summer.
When calculating livestock water supply needs, use the highest possible daily intake for your kind and class of livestock plus evaporation losses and four to seven days of storage capacity to account for high evaporation losses and heat stress during the summer.
You should know the flow rate of your wells or pipelines, and how many animals can be supported by each of your water sources, under adequate precipitation conditions as well as drought conditions. The quality of water from various sources must also be considered.
What are your possible sources of water? Many producers advise having a back up source of water in case your primary water resource is insufficient or breaks down. Stock dams may not be reliable as the only sources of water during drought. Purchasing portable tanks may be an option, as might investing in a water development project installing pipelines or new wells.
