Abstract:
This brief National Rivers Authority (NRA) leaflet describes the River Mirmram. The River Mimram is a chalk stream rising near Kings Walden, Hertfordshire although a dry valley extends further north west towards Luton. The perennial source is at Whitwell watercress beds and the river flows in a south easterly direction to join the River Lee in Hertford, 1km west of Hertford Castle. From its source to its confluence with the Lee it is about 23km long. The fall in the river between Kings Walden and its confluence with the Lee is approximately 60 m. The average rainfall in the Mimram catchment is 650mm. The Mimram catchment covers an area of 145 square km. The average flow in the Mimram is 11,500 cubic metres per day.
