From Brownhills it would drop through 30 locks on its route past Lichfield to reach Huddlesford Junction.
However, the company obtained a second Act in 1794, before the original canal was completed, which authorised an extension eastwards from Birchills, passing through Pelsall to reach more collieries at Brownhills, close to Catshill Junction, and on to the site of Ogley Junction, from where it would descend through thirty locks to reach Huddlesford Junction, to the east of Lichfield.
In 1956 the reservoir is purchased by Brownhills Urban District Council from the British Transport Commission for £5,600 and the reservoir is renamed Chasewater.
