Bentley Brook
The 883rd longest river in the world
Bentley Brook is a stream in Derbyshire, England. It rises on Matlock Moor, flowing south through Cuckoostone Dale, under the A632, into Lumsdale, gathering the valley's waters—notably from Knabhall Brook, out of Tansley, itself dammed and supporting large mills. In Lumsdale it enters a now disused mill pond or reservoir, then flows over a waterfall in the course of passing several historical mill ruins. Finally, it runs through control gates into the outside bend of a tight oxbow of the River Derwent, just beyond Hall Leys Park in Matlock. Although only about five miles in length, Bentley Brook is classed as a 'main river' by the Environment Agency.
