Western Run is a tiny, meandering brook that flows across a peaceful and genteel valley in upper Baltimore County and joins with Gunpowder Falls east of Cockeysville. As the river winds through a beautiful rolling valley that is dotted by beautiful, old farmhouses, horse farms, and huge mansions it rushes over countless riffles formed by fine gravel and over some rubbly rapids formed by remains of old dams. While the water is very easy, complications arise from fallen trees, barbed wire, and wooden and electric fences.
