Harthill ponds are as series of 3 reservoirs and are today a popular coarse fishing and sailing site. They were formed in the 1760s by the damming of the Derbyshire Dyke and they acted as a water reserve for the Chesterfield Canal (see the canal pages). The waters were later used for the boilers of Kiveton Pit.
Below is the boat house of the dinghy sailing club.
The ponds are also connected to Pebley pond (this link also gives an aeriel view of the Pebley/Harthill pond system).
