A 'Tin Town' corrugated iron temporary village was built near Fernilee for the navvy workers.

The hamlet of Goyt's Bridge and Errwood Hall (the Grimshawe family mansion) were destroyed in the 1930s to prevent any pollution of the water running into Fernilee Reservoir.

The reservoir provides drinking water for Stockport town and the surrounding area.

[2][3][4] The lower Toddbrook Reservoir at Whaley Bridge drains into the River Goyt but is fed from the Todd Brook stream.

The disused Cromford and High Peak Railway line (which connected the High Peak canal at Whaley Bridge with the River Derwent in Cromford) runs along the east side of the reservoir.
