Special Notes: To ensure passage, boaters must arrive at least 1.5 hours prior to closing. Swing bridge at upper lock with clearance of 2.9m (9.5 ft). Swings on demand. Boaters approaching from the upstream side who wish to overnight should head left (north) at buoy NM2 to the greyline docking in the basin rather than heading to the blueline docking at the upper lock. Space is often limited at the blueline docking and the channel is too narrow for larger boats to turn around.
Of Interest: The Merrickville locks are located at the earliest mill site on the Rideau River, that of Roger Stevens, who built a mill here in about 1790. But it was William Mirick, who, a couple of years later, took over the mill and established a community which was thriving by the time of canal construction. The locks bypassed the mills, leaving them intact, allowing Mirick to continue his business. They are spaced out, three detached locks, taking advantage of the natural topography. The largest blockhouse on the Rideau, built here in 1832, is now operated as a museum. Merrickville is known as the “Jewel of the Rideau” and features many beautiful heritage buildings as well as many shops (including Friends of the Rideau's "The Depot", located adjacent to the Blockhouse). The Rideau Migratory Bird Sanctuary is located just upstream from Merrickville.
Notes: Gas is available near the lower lock at Ayling's Boatyard. Groceries and supplies are readily available in Merrickville.

The three locks in Merrickville are in a canal channel built to bypass the original mills built by William Merrick (located near where Ayling's Marina now sits). Merrickville hosts the largest of four blockhouses built along the Rideau, it is located adjacent to the upper lock. Overnight docking is available at either Ayling's Marina or at the Parks Canada docks in "The Pond."
