Spillway

Engineering brick walls with heavy gritstone coping. Upper end has ground paddle and radial arm gear by Coalbrookdale Co. surrounded on 3 sides by heavy stone blocks. Paddle gear probably designed by George Buck during engineering improvements (1819-31). Iron shod timber gates removed at time of inspection, August 1994. Narrowing of main pound walls also of blue brick.

On N side, a feeder stream with tapered spillway, having a central flume controlled by a ratchet paddle gear, and C20 60m spun concrete culvert to a blue brick interceptor bay at the side of the tapering walls of the main pound.
