Lake Scugog

A shallow, island-defined Kawartha lake known for warm-water fishing and its connection to the Trent–Severn Waterway.

Lake Scugog is a broad, shallow lake spanning Durham Region and the City of Kawartha Lakes. Its warm-water fishery, large central island and connection through the Scugog River give it a distinctly different character from Ontario’s deeper Canadian Shield lakes (Kawartha Conservation, 2010).

Location Regional Municipality of Durham and City of Kawartha Lakes, Ontario.

About the Lake

Lake Scugog is one of the largest water bodies in the Kawartha Lakes area by surface area, yet it is exceptionally shallow, averaging only 4.6 feet deep. Its present water level is maintained by the Lindsay Dam, and water leaves the lake through the Scugog River before continuing north through Lindsay to Sturgeon Lake. Because of its shallow basin and nutrient-rich environment, aquatic vegetation is an important part of Lake Scugog’s ecological character. (Kawartha Conservation, 2010)

This makes Lake Scugog fundamentally different from lakes such as Joseph or Rosseau: its identity comes from broad shallow water, wetlands and warm-water habitat rather than deep, clear basins.

Reading the shoreline

Lake Shape & Shoreline Character

Lake Scugog has an irregular, two-basin shape dominated by the large Scugog Island, with major water channels passing along both sides of the island. Unlike the rocky shorelines of many Muskoka lakes, much of Scugog is shallow and associated with wetlands, aquatic vegetation and softer glacial sediments; its average depth of only 4.6 ft also makes water depth an important consideration for boaters. (Kawartha Conservation, 2010)

What makes the outline distinctive: the large central island effectively divides much of the lake into eastern and western waters, making Scugog Island itself the defining feature of the lake’s silhouette.

Things to Do

Lake Scugog combines lake recreation with the walkable waterfront of Port Perry. The Port Perry Waterfront Trail System follows approximately five kilometres of lakefront, while Palmer Park, Birdseye Nature Walk and Rotary Environmental Park provide places to walk and enjoy views of the lake. Scugog Island Crown Land also provides lake access, while boating and fishing are major recreational uses of the lake. (Township of Scugog, n.d.-a, n.d.-b)

Visitors interested in local history can also visit the Scugog Shores Museum Village and Archives, which interprets the history of the Lake Scugog area and includes exhibits concerning First Nations history and traditional use of the lake’s natural resources. (Township of Scugog, n.d.-c)

Boating

Lake Scugog has numerous public boating access points. On the Durham side, municipal ramps include Port Perry, Caesarea and Scugog Island, while the City of Kawartha Lakes maintains additional Lake Scugog launches around areas such as Pleasant Point, Washburn Island and Little Britain. (Township of Scugog, n.d.-d; City of Kawartha Lakes, n.d.)

Lake Scugog also connects to the larger Trent–Severn Waterway. Boats can travel north through the Scugog River to Lindsay, where Lock 33 provides access between Lake Scugog and the main Trent–Severn navigation channel. From there, the waterway connects with Sturgeon Lake and the other Kawartha lakes. Parks Canada notes that channel depths beyond Lindsay can vary considerably and that a fixed bridge has approximately 3.7 metres of clearance. (Parks Canada, n.d.)

What makes boating different: Scugog is dramatically shallower than lakes such as Muskoka, Rosseau or Joseph. Rather than deep-water island cruising, boating here involves shallow-water awareness and navigation toward the Scugog River and Trent–Severn system. Kawartha Conservation notes that the lake contains extensive shallow areas and aquatic vegetation. (Kawartha Conservation, 2010)

Fishing

Lake Scugog is a warm-water fishery. Kawartha Conservation reports that no cold-water fish species are native to the lake and that its warm-water fish community is supported by natural reproduction. Species recorded in the lake include muskellunge, smallmouth and largemouth bass, yellow perch, black crappie, bluegill and pumpkinseed, among others. (Kawartha Conservation, 2010)

Fishing remains important enough that the Ontario government includes Lake Scugog among the province’s 12 Provincially Significant Inland Fisheries that receive additional monitoring. A 2020 provincial recreational fishing survey found that fishing effort on Scugog was strongly oriented toward bass, sunfish and crappie. (Government of Ontario, 2026; Ontario Ministry of Natural Resources and Forestry, 2023)

Lake Scugog also has special fishing regulations. Walleye fishing is currently closed year-round in Lake Scugog and the associated Scugog River waters covered by the exception, so visitors should always consult the current Ontario Fishing Regulations before fishing. (Government of Ontario, n.d.-a)

What makes fishing different: unlike the deep, cold-water lake-trout fisheries of Muskoka cottage country, Scugog is primarily a shallow, warm-water bass, panfish and muskellunge environment.

Swimming

Public swimming is available at Kinsmen Beach at Palmer Park in Port Perry, which is included in Durham Region’s seasonal beach-monitoring program. The beach sits directly beside Port Perry’s waterfront parks and downtown, giving Lake Scugog a more community-oriented public waterfront than many cottage-dominated lakes. (Regional Municipality of Durham, 2023)

Lake Scugog has experienced blue-green algae blooms, and Durham Region has issued advisories in recent summers. This does not mean the entire lake is continuously unsuitable for swimming, but visitors should check the current Durham Region beach report and avoid water where visible algae or an advisory is present. (Regional Municipality of Durham, 2025)

Nearby Communities

Port Perry is the principal waterfront community on the southwestern side of Lake Scugog, with its historic downtown, waterfront parks, marina and municipal boat launch. Caesarea and View Lake lie along the eastern side, while Pleasant Point, Little Britain and Washburn Island are associated with the northern and northwestern portions of the lake. Lindsay lies farther north along the Scugog River and provides the boating connection to the main Trent–Severn Waterway at Lock 33.
