Bobs and Crow Lakes are part of the Tay River system and the Rideau River watershed and an integral part of the Rideau Canal waterway. The Bobs and Crow Lakes watershed comprises about 5% of the total Rideau watershed. Much of what we now know as Bobs Lake did not exist prior to the construction of the dam at Bolingbroke at the outlet to the Tay River and the flooding of the low-lying lands in 1870-1871. Bobs Lake and Crow Lake are an off line reservoir supporting the water supply for navigation of the canal system.
The relationship between the Rideau Canal system and Bobs and Crow Lakes is probably the single most significant feature of the lakes because the lakes are no longer natural water bodies. Water levels are regulated for the management of the Rideau Canal. The dam at Bolingbroke is owned and operated by the Rideau Canal Office (RCO) of Parks Canada. Operation of the dam affects the whole environment of the lake and how we interact with it.
Bobs and Crow Lakes are connected bodies of water situated 30 kilometers west-southwest of the town of Perth and 45 km north of the City of Kingston. Road access is via secondary roads off Road 38 to the west, which connects Kingston in the south and Sharbot Lake in the north. County Road 8 (also known locally as Mast Road) provides main road access from Road 38 to the southern shores of Bobs Lake. Crow Lake Road runs between Road 38 and County Road 36 and provides access to Crow Lake and the northern and eastern shoreline of Bobs Lake. County Road 36 connects this part of Bobs and Crow Lakes to Highway 7 to the north and to Westport, Kingston and Gananoque to the south and southeast.
