Toddbrook Reservoir, a feeder for the Peak Forest Canal, opened in 1838. It is above the town of Whaley Bridge in the High Peak area of Derbyshire, England. The reservoir is a Site of Special Scientific Interest (SSSI) providing habitats for herons, ducks and other animals and fish, while rare mosses and liverworts grow on its shores, particularly short-lived species that grow on seasonally exposed mud. The reservoir is used for sailing and angling. The Peak District Boundary Walk runs around the eastern end of the reservoir. The reservoir is owned by the Canal & River Trust and, like the nearby Combs Reservoir, is a feeder reservoir for the Peak Forest Canal. The feeder runs through Whaley Bridge, and with the Combs feed enters the canal system in a pool close to the transhipment shed at the Whaley Bridge canal basin.
