Mitchell Lake is a small, artificial lake in the Great Lakes Basin and located in the city of Kawartha Lakes in Central Ontario, Canada. [1] [2] [3] [4] The lake was formed sometime in the first decade of the twentieth century alongside the construction of the Kirkfield Lift Lock, which was completed and operational by the end of 1907. [5] It is part of the summit of the Trent–Severn Waterway, the middle of a connection via canals of Balsam Lake on the Gull River system, which flows eventually to Lake Ontario, and the Kirkfield Lift Lock and Canal Lake on the Talbot River system, which flows to Lake Simcoe and eventually to Lake Huron.

History

Prior to flooding, the Grass River (now Grass Creek) flowed through the centre of marshland above which the current lake sits in Eldon Township, Victoria County. It entered from the south-west, reaching Fennel Road (Kawartha Lakes Road 35) where it now crosses the Trent Canal. From here it turned west and followed the same course as the modern canal to Portage Road (formerly Ontario Highway 48, today Kawartha Lakes Road 48). Passing under the road, it resumed a north-easterly course towards the village of Victoria Road, where it flowed as it continues to today, now controlled by a dam, westward into the Talbot River. [6]

Modern Mitchell Lake

Like many of the lakes of the Kawarthas, Mitchell Lake enjoys use by recreational cottagers. However, most of the lake is relatively shallow (Between 3 and 6 feet deep), swampy, and filled with partially or wholly submerged tree stumps remaining from before the flooding. As such, cottages are sparse outside of the canal zone and south eastern section of the lake. The shallow south-western section of the lake is isolated from the rest by Hartley Road, which crosses the lake by causeway, and is only navigable by canoe.

The former path of the Grass River north of Kawartha Lakes 48 is still visible beneath the shallow and undisturbed waters of the lake. [7]

Mitchell Lake suffers from man-made tides. Essentially reaching high tide for the summer months , and low tide throughout the winter. Each year on thanksgiving weekend the Trent-Severn Waterway is closed, Mitchell lake floodplain drops its water elevation 2ft, and the shoreline recedes up to 20ft. In late May the Trent-Severn Waterway opens up again and the Mitchell Lake floodplain raises its water elevation 2ft, and the shoreline expands up to 20ft. Since this floodplain used to be a forest, decaying underwater biomass raises small islands and releases dissolved methane gas into the water, acidifying the water. The southern portion exposes the ancient tree stumps during low tide. Mitchell Lake floodplain has been completely overrun by invasive Eurasian Milfoil weed (Myriophyllum spicatum). It has decimated the oxygen and natural flora of the water, and begun spreading to other lakes on the Trent-Severn Waterway via boat travel.

Kirkfield

Kirkfield is a village located in the city of Kawartha Lakes, in the Canadian province of Ontario. The unincorporated village was named in 1864 after the initial name, Novar, was rejected by the government. A list of 8 possible choices was then offered. The village, being predominantly Scottish at the time, chose Kirkfield, after Kirk' o' Field in Edinburgh. It is home to Lock 36 of the Trent-Severn Waterway, a hydraulic lift lock which connects Canal Lake and the artificially flooded Mitchell Lake. Travellers and commuters pass through Kirkfield regularly while travelling on Highway 48 west towards Highway 12 and east towards Highway 35.

Little Lake (Peterborough) Lake in Peterborough, Ontario

Little Lake is a small lake on the Otonabee River in the city of Peterborough, Ontario, Canada. The lake is in the downtown of the city and is used for fishing, swimming, boating, and for various special events. The lake lies on the water route from Lake Ontario to the Kawartha Lakes. The area around the lake was first settled by Europeans around the start of the 19th century. Steam- and water-powered saw mills were built on the lake and on the river upstream to prepare lumber for shipment overseas. Sawdust and other debris from the mills polluted the lake, killed the fish and clogged up the navigable channels. The smell was so noxious it drove residents near the lake to move. These problems were resolved by the end of the century, when the lake became a hub on the new Trent-Severn Waterway from Lake Ontario to Lake Huron. However, industries attracted by cheap hydroelectric power, such as General Electric used the lake for disposal of industrial chemicals for many years. The pollutants seems to be mostly contained in the sediment, and the lake is now considered safe for recreational use.

The Rosedale River is a river in the City of Kawartha Lakes in Central Ontario, Canada. It is in the Great Lakes Basin and is part of the Trent–Severn Waterway. The river is named after Rosa Dale, the wife of settler John Cameron, who first settled the area of nearby Fenelon Falls.
