Dam of a fishpond 430m WNW of Poulton Farm.
Reasons for Designation
A fishpond is an artificially created pool of slow moving freshwater constructed for the purpose of cultivating, breeding and storing fish to provide a constant and sustainable supply of food. They may be dug into the ground, embanked above ground level, or formed by placing a dam across a narrow valley. Groups of up to twelve ponds variously arranged in a single line or in a cluster and joined by leats have been recorded. The ponds may be of the same size or of several different sizes with each pond being stocked with different species or ages of fish. The size of the pond was related to function, with large ponds thought to have had a storage capability whilst smaller, shallower ponds were used for fish cultivation and breeding. Fishponds were maintained by a water management system which included inlet and outlet channels carrying water from a river or stream, a series of sluices set into the bottom of the dam and along the channels and leats, and an overflow leat which controlled fluctuations in water flow and prevented flooding. Buildings for use by fishermen or for the storage of equipment, and islands possibly used for fishing, wildfowl management or as shallow spawning areas, are also recorded. The tradition of constructing and using fishponds in England began during the medieval period and peaked in the 12th century. They were largely built by the wealthy sectors of society with monastic institutions and royal residences often having large and complex fishponds. The difficulties of obtaining fresh meat in the winter and the value placed on fish as a food source and for status may have been factors which favoured the development of fishponds and which made them so valuable. The practice of constructing fishponds declined after the Dissolution of the Monasteries in the 16th century although in some areas it continued into the 17th century. Most fishponds fell out of use during the post-medieval period although some were re-used as ornamental features in 19th and early 20th century landscape parks or gardens, or as watercress beds.
Documentary sources provide a wealth of information about the way fishponds were stocked and managed. The main species of fish kept were eel, tench, pickerel, bream, perch, and roach. Large quantities of fish could be supplied at a time. Once a year, probably in the spring, ponds were drained and cleared. Fishponds are widely scattered throughout England and extend into Scotland and Wales. The majority are found in central, eastern and southern parts and in areas with heavy clay soils. Fewer fishponds are found in coastal areas and parts of the country rich in natural lakes and streams where other sources of fresh fish were available. Although 17th century manuals suggest that areas of waste ground were suitable for fishponds, in practice it appears that most fishponds were located close to villages, manors or monasteries or within parks so that a watch could be kept on them to prevent poaching. Although approximately 2000 examples are recorded nationally, this is thought to be only a small proportion of those in existence in medieval times. Despite being relatively common, fishponds are important for their associations with other classes of medieval monument and in providing evidence of site economy. The dam of a fishpond 430m WNW of Poulton Farm survives well and is particularly important because it has both early and royal documentary evidence relating to it. It will contain archaeological and environmental evidence relating to its construction, maintenance, longevity, social and economic significance, fishery information and landscape context.
This record was the subject of a minor enhancement on 16 July 2015. This record has been generated from an "old county number" (OCN) scheduling record. These are monuments that were not reviewed under the Monuments Protection Programme and are some of our oldest designation records. As such they do not yet have the full descriptions of their modernised counterparts available. Please contact us if you would like further information.
This monument, which falls into two areas, includes the dam or pond bay of the ‘King’s Bay Mead’ or ‘Great Bay’ fishpond situated in the base and across the wide valley of the River Og upstream of its confluence with the River Kennet. The dam survives as two lengths of flat topped linear bank the western section is approximately 95m long, the eastern 67m long and the bank is up to 20m wide and from 2.8m up to 4m high. Where a breach has been made by the river a modern weir and small bridge have been inserted. The fishpond was constructed in 1204 and is recorded in the Pipe Roll of King John in 1206. The pond produced fish for the Royal Manor of Marlborough.
