A few years ago, the Association had a bathymetric map made of our four lakes. The work was with TrakMaps of St. Donat in the Laurentians.
The map was named in honor of Peter Palmer, a founding and very active member of the Association whose nickname “Mr. Mayor” said it all.
To acquire a copy, please contact the association.
I am also adding a map from Wentworth showing the beaver dams. Carte_topo_argenteuil_76035_barrages_castors
