Farmers should secure livestock in safe areas, such as higher ground or berms, to protect them from flooding. Removing fencing in flood-prone areas can allow animals to move to safer locations. Mark animals with identifiers like ear tags, paint, or clipped initials to help recover them if they become lost. Stock up on feed, water, and supplies to sustain livestock for at least three days, and store these items in a way that prevents contamination from floodwaters.
