The River Dyfi between Aberdyfi and Derwenlas was often a very busy waterway when the tide was up in Victorian times.

Derwenlas also had three boat-building yards, and 36 wooden vessels of up to 75 tons were built there from local oak up to 1869. Most of these were used for coastal trade around Britain.

The map above shows Derwenlas, the diverted River Dyfi, and the railway line in the early 1900's. One of the original loops in the course of the river was completely cut off by the railway.
The railway took over most of the commercial trade from the river boats, and the boat-builders and sailors left the area for good. The lime kilns near the port which were used to burn limestone to produce lime for use as a fertiliser also closed down.
