Big wakes a growing concern for Brome Lake

By : Alison Chave

While Brome Lake is large enough to attract wake sports enthusiasts, experts and local advocates are increasingly concerned about the impact wake boats are having on the lake.

Unlike traditional recreational boats, wake boats are specifically designed to create large V-shaped waves using heavy ballast systems. On a lake such as Brome Lake — with a maximum depth of about 10 metres, extensive shallow areas, narrow sections, and dense shoreline development — those wakes can have significant environmental impacts.

The Town of Brome Lake (TBL) and Conservation Lac Brome (CLB) have increased nautical patrols and introduced pamphlets and mobile applications to identify sensitive areas and encourage responsible boating. Still, many residents believe stronger measures are necessary.

Environmental Impacts

Environmental concerns linked to wake sports are becoming increasingly visible around the lake. Large wakes can disturb bottom sediments, releasing phosphorus that contributes to algae blooms and declining water quality.

In shallow and vegetated areas, repeated wave action can:

• uproot aquatic plants
• damage fish habitat
• reduce water clarity

Shoreline erosion is another growing concern. Powerful wakes can travel quickly across the lake, striking banks, docks, and retaining walls with force.

Property owners increasingly report shoreline damage and loss of natural vegetation buffers that help stabilize the lake’s edges

Growing Conflicts Between Lake Users

Beyond environmental impacts, conflicts between lake users are also increasing.

Brome Lake is shared by:

• swimmers
• paddlers
• sailors
• rowers
• anglers
• recreational boaters

Large wakes can create unsafe and uncomfortable conditions for other users, especially during busy summer weekends.

Regulation Challenges

Regulation of wake sports remains complex. Federal boating laws administered by Transport Canada focus primarily on navigation and safety rather than wake size. Provincial environmental rules protect habitats but do not directly regulate wake sports.

In practice, municipalities and lake associations carry much of the responsibility through:

• local bylaws
• codes of conduct
• navigation restrictions

Across Quebec, many lakes facing similar pressures have followed a familiar pattern:

1. increasing wake boat use
2. growing environmental degradation and user tensions
3. stricter municipal restrictions and calls for federal intervention

Debate Continues

Debate continues over the best approach for Brome Lake.

Conservation Lac Brome (CLB) strongly recommends that wake surfing take place only in areas:

• at least seven metres deep
• more than 300 metres from shore

These are stricter standards than the current privileged area.

The administration appears to be focusing on:

• increased patrols
• enforcement of existing rules
• a new urban plan limiting the size of new constructions to preserve soil permeability

Still, many residents and conservationists argue that long-term navigation solutions are urgently needed as lake use intensifies, including requests for changes to federal regulations.

There are also questions about whether:

• the number of motorboats
• or the types of motors permitted on the lake

should be limited.

Boat numbers continue to rise:

• 546 motorboats in 2015
• about 700 motorboats in 2024

Recommendations for Wake Sport Users

For now, wake surfers and boarders can help preserve the environment by:

• staying in the deepest central areas of the lake
• keeping a large distance from shore
• avoiding ballast-heavy surf setups
• limiting repeated passes in the same area

They can also:

• obtain a TBL Nautical Practices pamphlet and map identifying sensitive and wake surf zones
• download CLB’s ONDAGO app to geolocate themselves
