The River Doe Lea is a river which flows near Glapwell and Doe Lea in Derbyshire, England. The river eventually joins the River Rother near Renishaw. The river contained 1,000 times the safe level of dioxins in 1991, according to a statement made by Dennis Skinner, (MP) in the House of Commons in 1992. The river flows through the site of the former Coalite plant near Bolsover, where coke, tar and industrial chemicals were manufactured until the plant closed in 2004. The stream section is designated an SSSI for its geological interest.
