A short stroll under overcast skies from the hamlet of Winterburn, located 3 miles or so north of Gargrave. Our route was up the wooded valley following Winterburn Beck, (notice a theme here?). The track is metalled, although private all the way to the reservoir. Frustratingly the right of way veers off to the left only 50 metres away from the dam. Lots of signs from British Waterways saying private etc, however a short trespass was in order to catch a glimpse of this little known stretch of water. Photo's taken, we retreated and made our way to the car by higher level field paths, getting caught in a rain shower just before we got back. I was surprised to see the British Waterway signs at the reservoir, presuming it had been built as a water supply for towns and villages in the Airedale. It was however constructed for the Leeds-Liverpool Canal in the late 1800's, canals of course use lots of water through the locks. Hence the British Waterways signs, I don't quite see why it must be off limits to the public though.
