Iron guard rail c.150 x 12mm extend along the narrowing of the upper pound and the headland between this and Guilsfield Canal arm. On NW bank, radial-arm paddle gear by Coalbrookdale Co. surrounded on 3 sides by heavy stone blocks. Probably designed by George Buck during engineering improvements to canal (1819-31).
