The Bain valley was formed by a glacier in the most recent ice-age and , although small , is very obvious . The River Bain is very susceptible to flooding and many floods have occurred during its history , about once every 30 – 50 years , the most recent being the 2007 United Kingdom floods , when the river overtopped its banks all along its course . Horncastle was particularly badly hit
