The
Kelvin rises on watershed of Scotland on the moor south east of the village of
Banton, east of
Kilsyth. At almost 22 miles (35 km) long, it initially flows south to Dullatur Bog where it falls into a man made trench and takes a ninety degree turn flowing west through Strathkelvin and along the northern boundary of the bog parallel with the
Forth & Clyde Canal.
