Since 2006, Bylaw Q2-r.8 requires the mandatory pumping of septic tanks for all properties in Ogden. This measure protects the quality of groundwater and surface water, particularly Lake Memphremagog.
The riparian buffer zone along the shores of Lake Memphremagog and other waterways in Ogden plays a crucial role in protecting water quality. It filters runoff, prevents erosion, provides wildlife habitat and helps prevent blue-green algae blooms.
Residents living along a shoreline are required to maintain a natural vegetation strip of at least 10 to 15 metres from the high-water mark. Cutting, clearing or any construction within this zone requires authorization from the municipality.
The MRC de Memphrémagog offers a subsidy program for the purchase of composters and rainwater recovery barrels. Ogden residents can receive a 50% reimbursement on the purchase price. To take advantage of this program, complete the form below and submit it to the municipal office located at 1225 Chemin Owl’s Head, Mansonville.
Ogden is home to several wetlands of ecological importance, including the Mud, Tomkins, Marlington and Ticehurst marshes. These environments act as natural sponges, filtering water, storing carbon and providing critical habitat for many species of birds, amphibians and aquatic plants.
These wetlands are protected under provincial legislation and Ogden’s zoning bylaw. Any work within or near a wetland requires prior authorization. For more information on wetland conservation:
