Menehune Fishpond, dating from about 1,000 years ago, was formed by a 900-foot (275-metre) stone wall at a bend in the Huleia Stream; according to legend, the wall, 4 feet (1.2 metres) wide and 5 feet (1.5 metres) above water level, was built in one night by the (“little people”), who were said to have accomplished great construction feats. Also near Lihue is Huleia National Wildlife Refuge (closed to the public), which protects the wetlands for endangered native Hawaiian birds. A waterlogged pond or marl pit has been cut into the bank's E end.To the SW of the moat lies an irregularly-shaped grassy, boggy area with maximum measurements of 45m x 21m that is the site of a former fishpond now partially drained and infilled.
A grassy outer bank 9m wide x 0.6m high flanks the NE arm and was originally a dam designed to raise the water level to flood the moat.
However, moated sites were built throughout the medieval period, are widely scattered throughout England and exhibit a high level of diversity in their forms and sizes.
They form a significant class of medieval monument and are important for the understanding of the distribution of wealth and status in the countryside.
Many examples provide conditions favourable to the survival of organic remains.
The monument is unencumbered by modern development and will possess further archaeological evidence of Hough Hall and its associated buildings together with further evidence of activity pre-dating construction of the moated site.
Adjacent to the moat's SW arm is a grassy ancillary enclosure measuring c.40m x 70m that is crossed by a grassy track running from Hulseheath Lane to the fishpond.
