(What do these stats mean?)

This was probably a pretty sizeable waterfall at one time, but has been largely altered by the addition of a dam. It is found near the corner of Cascade Street and Water Street. Built across the Seguin River in the early 1900s, the dam is low but wide with at least four different sections of concrete spillway. At higher flows, water slides down a number of inclined ramps. Exposed bedrock still exists at the bottom of the dam, allowing the Seguin River to still pick its way over and through some tilted rock sections for the last few metres of the fall. The total drop is about 7 m, with about 5 m occurring at the dam. There isn't a lot of waterfall left here, but given it's easy access and view from Cascade Street, it's worth a stop. I think that the unique ramp-style spilways add a different texture to your waterfall picture collection.  (updated June 20, 2014).
