Cameron Lake is situated around the town of Fenelon Falls in the Kawartha Lakes Region of Ontario and is a mile north of Sturgeon Lake. Cameron Lake is twenty-three feet above Sturgeon Lake and drains via the Fenelon River. The lake occupies the expanse between locks 33 and 34 on the Trent-Severn Waterway.
Cameron Lake stretches four miles from north to south and two miles from east to west. Similar to Balsam and Sturgeon lakes, Cameron Lake is located in the relatively narrow belt of limestone topography that lies above the livestock and grain farmland to the south, and the Precambrian Canadian Shield country to the north. The limestone topography dictates the type of waterfront found on the lake - lots are most often level, and generally not steep to the water. Shorelines can be rocky (limestone boulders) or sandy, with older cottages often having concrete retaining walls. Landscaped lots with lawns and gardens are common. Insects tend to be less of an issue than in the Precambrian region. Water levels remain relatively constant throughout the year.
The lake has many properties with hard sandy waterfront, and there is a significant population of year-round residents.
