Butterley Reservoir, located near junction 28 of the M1 and easily accessible by following the National Heritage signs for the Midland Railway Centre, has a postal code of DE5 3QZ. Constructed in 1795 by William Jessop, it is the largest of three reservoirs built to supply the Cromford Canal, with the other two, Codnor Park and Butterley Park, no longer in existence. The reservoir was created by damming the Hartshay Brook and covers approximately 50 acres, holding an estimated 283 million gallons of water. In 1875, the Midland Railway extended the Ambergate to Pye Bridge line over the reservoir using a wooden viaduct with 22 spans of 9.1 meters each. This viaduct was later replaced by a stone causeway in the 1930s, which remains in place today. Thanks to the efforts of the Angling Club and their maintenance team, Butterley Reservoir has undergone changes over the years. Divided into two sections by the Midland Railway, which runs through it, the reservoir offers two separate fishing venues. Anglers who explore the reservoir will find good fishing opportunities, with shallow areas being advantageous during the summer months and pegs along the dam wall in deeper water being popular in colder months. Overall, Butterley Reservoir provides a peaceful and scenic location for angling enthusiasts to enjoy.
