Quick Tips:

Spinnerbaits and crankbaits are effective for producing mid-water bass and pike on The Guelph Lake Conservation Area. Surface lures cast into shoreline vegetation will produce explosive strikes from Largemouth Bass. Jigs tipped with live bait are successful in catching panfish and bass.

The Guelph Lake Conservation Area is a man-made reservoir on the Speed River, in the Township of Guelph/Eramosa. It is located upriver and slightly northeast of the city of Guelph, Ontario. The reservoir was created in 1974, with the construction of the Guelph Lake dam. The site is part of a 1,608 hectare (3,971 acre) conservation area maintained by the Grand River Conservation Authority.

Ever since the reservoir was created in 1974, The Guelph Lake Conservation Area has been popular for swimming and various beach activities. There are changing facilities, and two man-made sand beaches at Guelph Lake; however, the park does not maintain a regular lifeguard patrol.

The Guelph Lake Conservation Area has a camping area with 104 serviced sites with electricity and water and about 190 un-serviced sites in a variety of locations, including riverfront and forest. Approximately five kilometres of hiking and biking trails wind their way through a wide variety of natural wooded areas as well as tall stands of reforestation inside the conservation area. In addition, there is a recreational trail from downtown Guelph that follows the river to Guelph Lake.

The Guelph Lake Conservation area includes two beaches, and a venue for outdoor concerts. The concert area, which has a living roof, is located on a peninsula at the centre of the lake, and is the site of the annual Hillside Festival.

No outboard motor boats are allowed on Guelph Lake Conservation Area. The only motorized boats permitted on the lake are Jon boats, which are small row boat-style boats with an electric trolling motor. They can be rented from the boathouse at the main beach. Canoes and kayaks are popular on the lake and can also be rented from the boathouse.

Since the founding of the Guelph Rowing Club in 1998, the sport of rowing has grown in popularity at Guelph Lake. From 2000, the club has also served as home to the University of Guelph “Gryphons” Rowing Team. In 2008, a permanent boathouse was constructed on the shores of the lake. This boathouse provides facilities for a thriving community of competitive and recreational rowers.

Guelph Lake Nature Centre:
The Guelph Lake Nature Centre is one of several nature centres operated by the Grand River Conservation Authority. The Centre offers environmental education programs for schools, families and community groups, as well as environmental day camps and birthday parties.

Dam and power generation:
The dam at Guelph Lake Conservation Area is one of the main flood control installations on the Speed River. Each spring, melt-water runoff and seasonal precipitation is collected in the reservoir; during the summer, water is released slowly to regulate the flow of the river; and in autumn, the lake is drained to a much lower level, before it freezes over (partially or completely) during the winter. There is a small hydroelectric power generating facility at the dam.
