River Dunsop

[1] An aqueduct carrying water to Blackburn runs alongside.

[2] The catchment is primarily Millstone Grit, but the tributaries run through older shale and limestone strata[2] On 8 August 1967 Dunsop Valley entered the UK Weather Records with the Highest 90-min total rainfall at 117 mm.

The peak flow of the flood was deduced primarily from wrack mark evidence and roughness coefficients.
