Lake Kashagawigamog is situated within two geo-political jurisdictions. The eastern portion of the lake near the village of Haliburton is within the Municipality of Dysart et al. Nearing the village of Minden, the western portion falls within the Municipality of Minden Hills.
The lake itself is located in the Haliburton Highlands, a vast region of more than 600 lakes that stretch from the village of Norland on Highway 35 to as far north as Algonquin Park. It is the central lake in a five-lake chain running southwest from the town of Haliburton to as far as Minden. Connected to Grass Lake and Head Lake to the east, Soyers Lake to the north, and Canning Lake to the west, the lake is long and narrow. It is essentially a widening of the Drag River, which flows from Drag Lake into the chain of lakes at Head Lake and out again at Canning Lake where a dam is controlled by the Trent-Severn Waterway.
The lake is comprised of two basins connected by a narrow channel, the southwest basin being a little larger and wider than the northeast basin. Most of the shoreline is developed with cottages and resorts, but these are largely hidden from view by the forest of deciduous and conifer trees that grow right to the water’s edge. Almost all of the granite bedrock surrounding the lake is covered by a thin layer of topsoil, with few rock out-crops, and there are a number of sand beaches. There is one notable island, which is located in the southwest basin and supports four cottages.
