Big Humpty takes the River Medlock through a short but large egg shaped culvert.

This large brick and stone culvert takes the River Medlock around 600m near Philps park.

One of the culverts of the Chorlton Brook, dual arched brick goodness.

A brick channel culvert takes the Chorlton Brook under Platt Field Park.

Gorton Falls was built by the Victorians in 1876 to keep the increasingly polluted waters of the Gore Brook out of Debdale reservoir. Four aqueducts carry the culvert across the water with the rest hidden within the banks.

This is the drain that got me into draining. I found a dark filled entrance, heard the water and smelt the culvert smell. After heading back a bit more equipped I went in and got my first taste of an underground river.
