A bustling summer hub and a busy stop for cottagers, Coboconk gets its name from the native "Quash qua be conk" meaning "where the gulls nest" and is referred to by locals as "Coby". With a population of 800 Coboconk is a hub for cottagers and visitors to Balsam Lake Provincial Park.

Coboconk is the highest point of navigable fresh waters in the world. Balsam Lake (Rosedale) is the Summit of the Trent-Severn Waterway with a height of 256.3 meters. Balsam Lake is highest point in North America in which you can circumnavigate the world. This was confirmed by Roger Stanley the Kawartha sector manager for the Trent-Severn Waterway. When speaking with Roger he mentioned that this was common knowledge among his colleagues. This was later enforced when visiting the Trent-Severn Waterway Lindsay Lock Station when a lockmaster was also aware of this fact. There is no documentation this proves this about Balsam Lake, there is however a map distributed by the Trent-Severn Waterway that provides a profile of each lock stations elevation above sea level. By looking at the map it is evident that Balsam Lake is the highest point of the Trent-Severn Waterway, and more importantly the highest point in North America where you can circumnavigate the globe.
