Cottages For Sale on Lake Eugenia

Owning a cottage on Lake Eugenia

Lake Eugenia is a working reservoir that became a cottage lake. Ontario's provincial hydro commission flooded farmland on the Beaver River just before the First World War to feed a power station below Eugenia Falls, and the result is a lake of long bays, inlets and points where fields used to be. Today about 400 cottages line the shore.

It is a warm-water lake rather than a cold, deep trout lake. The fishing is bass and panfish, and the appeal is relaxed summer days on a sheltered shoreline. The big selling point is location: the Niagara Escarpment, Eugenia Falls, the Bruce Trail and the Beaver Valley ski hills are all close, so a cottage here works in February as well as July.

Because Ontario Power Generation still runs the lake as a reservoir and Grey Highlands licenses short-term rentals, owners deal with a few more rules than on a typical cottage lake. Read the buying notes below before you fall for a view.

History of Lake Eugenia

Eugenia was named for the Empress Eugénie, wife of Napoleon III. In 1852 a rumour of gold at the falls brought a rush of prospectors, but the shiny rock turned out to be pyrite. William Hogg put the area's first generator below the falls in 1893.

The Hydro-Electric Power Commission of Ontario took over the power project in 1912 and bought roughly 1,900 acres of farmland the next year. Crews cleared the land and dammed the Beaver River, creating the reservoir by about 1914. Water ran down two long wooden penstocks to a station with about 180 metres of head, the highest in Ontario, which supplied Owen Sound and Collingwood. By the 1950s local families were using the lake as a summer getaway.

In 1960 cracks in the original dam forced the commission to lower the reservoir by about 4 metres, leaving some cottages more than 15 metres from the new shoreline. A new earthen dam built in 1962 brought the lake back to its old level. Ontario Power Generation took over the station from Ontario Hydro in 1999.

Living on a hydro reservoir

Lake Eugenia exists to store water for the Eugenia generating station, so Ontario Power Generation controls the level, not a lake association or conservation authority. Ask the seller how the level has behaved over the seasons, and set up docks to handle some change. The 1960 drawdown is a reminder that the dam comes first.

Because the lake filled former farm fields and river valley, the shoreline is full of bays and inlets. That gives many cottages a sheltered, cove-like setting. It also means your view may end at the next point across the bay rather than a wide open horizon.

Bass and panfish fishing

This is a warm-water fishery. Largemouth and smallmouth bass are the main draw, with rock bass, yellow perch, sunfish and bullhead making it an easy lake for kids to catch fish from the dock. Check Ontario's fishing regulations for bass season dates before you go.

Water quality, algae and swimming

Grey Highlands tests Lake Eugenia weekly from June to September and posts results on its website. In 2026 the lake was rated okay to swim on every test date from May to October. The municipality also notes that elevated E. coli and blue-green algae blooms have happened here in some summers, usually in late summer or early fall.

If you see a bloom, assume it is toxic. Keep children and pets out of the water and do not drink untreated lake water. Cottagers can help by keeping septic systems in good shape and leaving natural vegetation along the shore.

Public access is limited

Most of the shore is private. The municipality's only public access is the boat launch and beach off Canrobert Street, run by the Eugenia and District Community Improvement Association. A seasonal launch pass is required and sold at the launch, and the beach has set hours on summer weekends and Friday afternoons. If you own on the lake, your own dock is your launch, but guests trailering a boat will need that pass.

Eugenia, Flesherton and the Beaver Valley

The hamlet of Eugenia has stores, restaurants and bed and breakfasts, and hosts a Gold Rush Days festival each year. Flesherton is just to the south for more services. Eugenia Falls drops about 25 metres into the Beaver Valley, and the Bruce Trail passes through, so hiking starts at your door.

For health care, Brightshores Health System runs a hospital site in Markdale. The Beaver Valley Ski Club is close by, which makes a winterized cottage here useful in every season.
