Stepped cascade

Selected for Google Maps and Google Earth

A stepped cascade just downstream from the first byewash, in operation still 1985.

Donald McLeods decision to use these simple devices was quite radical for the time and certainly the use of concrete was visionary as the stepped cascade is subject to erosive wear. They were a very economic way of keeping the speed of the water under control in those sections of the terrain where the natural fall was in excess of the designed fall, and by making the race a series of levels and waterfalls the erosion and transport of silt.
