Upper and Lower Ogden Reservoirs are half a mile to the west of the village of Barley, in the Borough of Pendle, Lancashire, England.

Initially water was collected from the river here and purified through filter beds, which began operation in 1892.

[1] The area's central geological feature is a north-westerly facing mounting escarpment, which extends between Whalley and the Aire Gap.

On the southern side of the valley, low gritstone crags are visible on parts of the hillside.

Blue Wood, which was originally planted in 1935 with Scots Pine, Sitka Spruce and Larch was felled and replanted in 1981.
