Monument record MNL 463 - River Lark; West Row Fen; The Mildenhall River (Rom)

Canalised course of the River Lark between approximately TL 640 765, near Bank Farm, northwards to TL 605 829, where the River Lark joins the River Ouse at Prickwillow (Cambs). Total length between these points of circa 7.2km.
It is suggested that the section northwards, from Lark Hall Farm, Isleham Fen (TL 624 797), is part of a Roman diversion which continued S from Lark Hall Farm across Baskeybay in Cambs to TL 640 765, as an old slade (an extinct river channel infilled with shell marl),SW of the present course (cf S1, S2, S3).
Note for Rom finds from river, or from eroded embanking material(!) where surroundings are below 0m contour (so deep fen location), see MNL 098 & 099 (pot scatters) and in Cambs (see Cambs HER & S1), from an extinct stream at Isleham is a C4 coin hoard, from the bed of the old slade at Isleham is a pewter hoard & indented beakers (S1-237)(R1)(R2) and `found in bed of river in Isleham Fen' are `rude draining tiles, samian and other pottery' (ibid; R3).
The present course of the Lark S of Lark Hall Farm, replacing the old slade is thought to be Med, possibly monastic.
Note: Baldwins Lode links into the Lark. The present course would certainly appear to have been in existence from the C17 onwards.
