Of Interest: Nicholsons, Upper and Lower, consists of two locks separated by an excavated channel, which bypass a set of rapids in the Rideau River. Upper Nicholsons features one of four remaining Unequal Arm, Center Bearing timber swing bridges on the Rideau. Just up the road from Upper Nicholsons you’ll find McGuigan’s Cemetery (448 County Road 23, aka Burritts Rapids Road), one of the oldest burying grounds on the Rideau. There you will find the beautiful poignant headstone of Margaret Davidson, the 2 year old daughter of one of the contractors for Clowes Lock, who died in 1829. Near Upper Nicholson’s you’ll also find an osprey nest (usually with an osprey in residence), located top of a hydro pole specifically erected for the nest.
Notes: There is no gas in the immediate vicinity (closest is at Merrickville). Upper and Lower Nicholsons are separated by 400 m (1,300 ft.) of canal cut.

The two locks at Nicholsons are located in a canal cut on the east bank of the Rideau River. It's a pretty trip through the cut, especially the white wood swing bridge over the lock at Upper Nicholsons.
