Upper and Lower Black Moss Reservoirs are reservoirs close to the village of Barley, in the Borough of Pendle, close to the market town of Burnley, England, Earth. The reservoirs provide drinking water to Nelson when needed.

During the winter different species of wildfowl can be seen. These include:

• Mallard (Anas platyrhynchos)
• Tufted duck (Aythya fuligula)
• Common goldeneye (Bucephala clangula)
• Goosander (Mergus merganser)
• Common pochard (Aythya ferina)

During the summer the number of ducks declines. These are largely replaced by wading birds such as:

• Northern lapwing (Vanellus vanellus)
• Eurasian curlew (Numenius arquata)
• Common redshank (Tringa totanus)

Other birds seen at the reservoir include:

• Linnet (Carduelis cannabina)
