A roughly 326m stretch of leat is depicted on OS County series (Flint. XXII.7 1873), leading from a wier on Emral Brook, believed to have fed a mill in the area of the later kitchen garden, also feeding a fishpond (Nprn309714), possibly concerned with Emrall Hall moat (Nprn309720).
Source: Canon Lee 1888 (AC 5th series 5), 29-41, 275-96 [30].
Leat partly filled in, otherwise utilised as drainage channel.
