Shoreline Protection
- Hits: 234
Lakeside resident destroys shoreline. Municipality sues. Read what the Quebec Superior Court decides.
This is a first in Québec. A property owner by lac Ouareau, in Lanaudière – near St-Donat – built a large house on a lake-front lot and decided to clean cut and level his shoreline even though the municipality, Notre-Dame-de-la-Merci (pop: 1100), had previously informed him of its 1996 by-law forbidding such action in the 10-15 meter lake protection band. The by-law is basically the same as Argenteuil’s.

2011 RSVL Lake Louisa Water Testing Report
- Hits: 291
The Voluntary Lake Monitoring Network (RSVL) has been testing the waters of Lac louisa since 2009. See the Lake Louisa locations map. See all sites tested by RSVL.
These results are from the three testing sites on the Lake. Site A, is above the deepest part of the lake about half-way between Murray's Island and Radimer's Point. Site B is at the Southwest end in the middle of Black Bay. Site C is at the Northeast end in front of Boyd's boathouse. The Ministry recommends that we complete 12 tests, one every 2 weeks throughout the season, May - October. This number could be achieved if we had some assistance.

Supporting the Health of Lake Louisa
- Hits: 329
We have reported to you on numerous occasions that according to the RSVL (le Réseau de Surveillance Volontaires des Lacs) the arm of MDDEP to which we send our collected water quality data every year, Lake Louisa continues to be a clean lake and continues to maintain its trophic status (oligotrophic). We have also reported that these results fail to explain why we see increasing water plant growth, reports of decreasing water clarity, occasional algae blooms and periphyton (slime) growth on shoreline rocks and structures.
In order to see if an additional scientific approach can provide some answers, we are adopting the new periphyton protocol provided by RSVL.

Please read the Wentworth Bylaw Summary for Protection of Shorelines, Lakes, Streambeds and Flood Plains before doing any work on your shoreline.
Read Wentworth Bylaw Summary for Protection of Shorelines, Lakes, Streambeds and Flood Plains.
Please be advised that the Wentworth Bylaw Summary for shorelines that is posted on our website may be misleading because it quotes the MRC RCI bylaw. The Wentworth Municipal Urban Planning Bylaws, as well as the draft modifications to these bylaws which were adopted in July of this year, are available on line on the Wentworth Municipality’s website at www.wentworth.ca.
The Municipality is planning to update the summary pamphlet over the winter and will post it and other pertinent literature on their website. In the meantime, Éric Boucher or Martine Renaud can answer any questions concerning the shoreline at 450-562-0701 or by e-mail at This email address is being protected from spambots.
