David Entwistle: Weston Water is the base for Otley Sailing Club. Water cold in spring but fantastically warm in late Summer. Amazingly clean clear water with lots of wildlife (pike, variety of water birds). It's about 1 mile up offroad track to Weston Water, and you need to join Sailing Club to get proper access. Also Leeds triathlon club train for swimming here. Sailers regularly swim in here at the end of a long hot days sailing. Beautiful.
