The Slyke refers to the small, open stream that ran, and still runs beneath the road, down Bagdale, emptying into the harbour at Dock End near the railway station. It was tidal as far as Bagdale Brewery. In the early 1800s, it was still possible to fish from the houses around what is now Victoria Square. During heavy rain or high tides the stream swells in size, and buildings in Linskill Square, Station Square and surrounding areas are still subject to flooding.
