Flooding threatened to breach the stables at Blue Acre Horse Rescue And Rehabilitation Centre in Ham Island, Old Windsor, on Monday leading bosses to take 21 of the 36 horses to stables in Englefield Green.
Older horses and smaller breeds such as Shetland ponies were moved while river levels rose to around four inches from getting into the stables. The charity could be worse hit if the water continues to rise into the already breached hay barn where around 1,500 bales of hay are stored.
Manager Bob Regan said: “Even if it gets just a couple of feet in there, that is probably 250-300 bales gone and they cost anywhere between £45 and £350 to replace. We have to wait and see. I have been here in Old Windsor since 1966 and this is the worst I have seen it affect us.”
