Harthill Reservoir is a fishing venue located near Rotherham in South Yorkshire. The site consists of a series of three linked ponds lying roughly North to South each split by a small bridge.
Along with nearby Pebley Pond they were originally built around 1770 as a feeder reservoir for the Chesterfield canal that is located Kiveton Park approximately two miles to the north. The largest of the ponds covers 20 acres and drops to 20 feet close to the dam wall. All three are currently used as fishing lakes. The main pond is also the home to the Rotherham Sailing Club.
