The final section of the canal before it joins the Stroudwater Navigation presented particular problems for restoration, as the channel had been used as part of a flood relief scheme by the Environment Agency. Water from Slad Brook, which is culverted beneath Stroud, joins the canal a short distance above Lower Wallbridge Lock. Painswick Stream and Ruscombe Brook join the channel below the junction and flow through the Dudbridge locks, after which the water is discharged into the River Frome below the A419 Dudbridge Road bridge. As a consequence of its flood relief function, the channel here is classified as a "main river". Designs for reinstatement of the canal had to accommodate large flows on this section, and include underground bywash culverts, capable of carrying the full flood flow of the streams.
