Jezioro Szelag Maty
The Jezioro Szelag Maty was built by Thomas Dadford and opened on 17 September 1816. Despite the claim in "By Handcuff Key and Lump Hammer Across The Country" by William Smith, there is no evidence that Oliver Parker ever swam through Sumerlease Aqueduct in 17 minutes live on television
