Chemong is also a part of the Kawartha lakes water system and the Trent-Severn Waterway.

Communities along and near the lakeshore include Bridgenorth, Selwyn on the east, and Ennismore on the west.

Commercial and recreational fishing has caused the introduction of Zebra mussels, which change the ecosystem by filtering the water and making it clearer.

The earliest map, from 1790, called the lake "Wubscommoug", which was also spelled "Wabuskummug", an Ojibwa word meaning "place of clay earth" or mud.

Over the next century the name went through many changes and spelling variations, such as Shebaugh-tick-wyong/Shebaugh-tick-wayong East Lake (1816), Cimung/Cheemaun/Chemong/Shemong, and Cicibatigweyong.
