Carved by Ice
The story of Bobs and Crow Lakes starts with the last Ice Age. A glacier scoured away metres of surface soil and bedrock, and its sheer weight pressed the land beneath it downward by as much as 30 metres. When the ice retreated, the land slowly rebounded, but unevenly, turning what had been fairly flat terrain into the rugged hills and lake-filled valleys we see today.
As the glacier pulled back, small bands of hunters followed the retreating ice north, tracking large game like mastodon and caribou along its edge. A single artifact found at the north end of Bobs Lake is our only direct evidence that people were here that early. When the tundra moved north with the ice, so did they.
Settlers, Sawmills, and a Dam That Changed Everything
1832: The Rideau Canal is completed, bringing Scottish and Irish canal workers south of Bobs Lake to settle as farmers and loggers.
1830s–1860s: More settlers arrive from Kingston, Westport, and Perth. Small communities take root around the lakes: farming begins around Burridge, milling starts at Bolingbroke (1848) and at Crow Lake Mills (1840), and a settlement forms at Crow Lake village (1862).
1870: Everything changes shape, literally. A new dam at Bolingbroke raises water levels by 15 to 18 feet, flooding the low-lying back bays: Long, Green, Buck, Mill, and Mud . This merges four separate bodies of water into one much larger lake. The Bobs Lake we know today is largely a product of that flood. Crow Lake, sitting at a higher elevation, is untouched by it.
1872: The K&P railroad reaches the western shore, and word of good fishing starts drawing anglers from Ontario and the U.S.
1870s–1920s: Visitors camp for weeks at a time or build simple cedar-log and wood-stove cabins along the shore. A handful of those original camps still stand today.
Much has changed since then, but the lakes still draw the same kind of visitor. People who came for the fishing- and stayed for the quiet- have spread word over the decades to their family and friends who also value time in the great outdoors. Much of our natural, simple shorelines have been preserved, and visitors often note the wild aesthetic compared to more developed Ontario lakes.
Where the Lakes Sit Today
Bobs and Crow Lakes rest on the Frontenac Axis, a ridge of Canadian Shield rock extending south from Algonquin Park. This is the meeting point of southern hardwood forest and northern boreal forest, which is why the shoreline mixes hemlock, white pine, and maple with patches of more diverse growth. The lakes are part of the Tay River system and the Rideau watershed, acting as a reservoir that helps supply water for the Rideau Canal's navigation system. To keep the canal at navigable water levels, our lake levels drop by about five feet throughout the season — worth planning for if you're adjusting docks or shoreline structures as the water recedes. We encourage explorers to take special care when boating in fall, when lower levels bring rocks and shoals closer to the surface.

Though it's commonly thought of as two lakes, the province actually classifies Bobs and Crow as one water body made up of nine basins: Crow Lake, Crow Bay, Buck Bay, Green Bay, Mud Bay, Mill Bay, Long Bay, and the Eastern and Western Bobs basins.
Shoreline ownership is a patchwork of private land and protected Crown and conservation land. Roughly 85 acres on Green Bay, once owned by a Westport doctor, are now preserved by the Nature Conservancy of Canada, and 120 donated acres form the Meisel Woods Conservation Area near Crow Lake, maintained by the Rideau Valley Conservation Authority.
So... Where Did the Names Come From?
Here's the fun part: nobody actually knows. Neither the provincial nor federal naming authorities have any record of how Bobs or Crow Lakes got their names. "Bobs Lake" only became the official spelling in 1939, when the Geographic Board of Canada dropped the apostrophe that once followed it.
Crow Lake's origin is even murkier. One local historian liked to imagine early loggers being woken at dawn by crows calling from the surrounding hills, much like he was. Others have pointed to a settler named Peter Crowe, though no connection to the lake was ever confirmed. An 1824 survey even labelled it "Clear Lake"- a name that clearly never stuck. In the end, the true story is lost to time, which might be part of the lake's charm.
