Of Interest: Clowes features a single lock, a waste water weir and an overflow dam, one of the few used on the Rideau. Colonel By originally planned all his dams to be overflow dams, but his experiences with spring flood on the Rideau soon changed his mind, and he added waste water weirs (a water control mechanism) to most of the locks. However, at Clowes and a few other places, he left the main dam as an overflow dam, the height of the dam being the level of navigation. The addition of the weir allows excess water to be quickly discharged.
* Time to actually go through the locks. Allow at least twice this time when trip planning. See Schedule Caveats.

A quiet solitude lock with an overflow dam in addition to the weir. A navigation note is that Clowes is located on the opposite bank (west) from the canal cut that leads to Nicholsons (east). The gentle currents of the Rideau River make this an easy transition.
