Ynys Gorad Goch consists of two small islands, the larger one containing a house and the smaller a rectangular building with a smoke tower at one end; the two islands are linked by a stone causeway. Two stone weirs curve round the SE and NW sides of the islands, forming funnel-shaped areas into which fish are swept when the tide is flooding. The fish are retained in the traps by the force of the tide and by upward-sloping grilles situated across the narrow openings.

The scheduled area includes the smoke tower and building and three-quarters of the Anglesey (NW) weir, which was rebuilt in 1924.

The house on the main island has been modernised but is in good condition. The earliest parts may date from the late 16th or early 17th C.

The smoke tower is probably of early 19th C date, and was used for smoking the catch. The tower is nearly square, set at the NW end of a rectangular building which has an extension (mid 19th C?) on the SW. The rectangular building measures 5.5 m by 3.8 m, with walls 0.5 m thick; it has a slate roof with modern timbers. There is one door in the SE gable and another in the SW side, leading into the extension. There is a window in the NE wall.

The tower is 1.8 m by 1.5 m, also with a slate roof, but with a hole in the top and a vent above, to let the smoke out. The extension is the full length of the rectangular building and about 2.7 m wide, with a two-seater privy at the W corner.

The monument is of national importance for its potential to enhance our knowledge of Post medieval fish and production industries. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structures themselves may be expected to contain archaeological information concerning chronology and building techniques.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
