Rake Brook Reservoir is a reservoir fed by two streams, including the eponymous Rake Brook, a tributary of the River Roddlesworth in Lancashire, England. The reservoir is adjacent to the two Roddlesworth Reservoirs. It was constructed in the 1850s by Thomas Hawksley for Liverpool Corporation Waterworks, and was designed to hold compensation water to maintain flows in the rivers, whereas the reservoirs at Lower Rivington, Upper Rivington and Anglezarke held water for the public water supply. Water from the reservoir was fed into Anglezarke reservoir by a 3.75 mi channel called The Goit. Construction of the reservoir was authorised by an Act of Parliament obtained in 1847, and the engineer Thomas Hawksley designed an earth dam which was 85 ft tall at its highest point and 1490 ft long. The reservoir was finished in 1857, and impounded 73 e6impgal of water when full.
