River Mimram

The Mimram Valley is named after the River Mimram, which rises from a spring to the north-west of Whitwell, in North Hertfordshire, England, and makes its confluence with the River Lea near Horn's Mill in Hertford. At Whitwell there are watercress beds which have existed since Roman times and these are fed by the same springs. The valley extends northwards where it becomes known as Lilley Bottom. Other sections of the valley are known as Kimpton Bottom and Codicote Bottom. The Mimram is crossed at Digswell by Welwyn Viaduct, carrying the East Coast main line.
