Fort Coulonge Water Aerodrome

While no official reason was published, the closure of a small, private water aerodrome like CA-0644 is almost certainly due to economic or personal reasons. This typically includes the owner ceasing private flight operations, the sale of the associated waterfront property, or the discontinuation of a small commercial service (like air taxi or tourism) that was no longer financially viable. There is no evidence of closure due to a major accident, environmental issues, or military conversion.

The site is no longer an active aerodrome. The water surface at coordinates 45.835, -76.752 is simply part of the Ottawa River, open to general marine traffic. Satellite imagery of the adjacent shoreline shows private residential properties with docks. There is no visible remaining dedicated aviation infrastructure such as commercial ramps, fueling stations, or hangars that would indicate its former use. The site has fully reverted to private, non-aviation use.

Fort Coulonge Water Aerodrome was a small, local seaplane base located on the Ottawa River. Its significance was primarily for general aviation and private use. Operations would have included:
- **Private Recreational Flying:** Providing river access for local or visiting pilots with floatplanes or amphibious aircraft, likely for access to cottages and recreational activities in the Pontiac region.
- **Bush Flying/Utility:** Potentially serving as a base for flights supporting local industries such as forestry, surveying, or hydro-electric operations in more remote areas.
- **Tourism:** It may have supported a small air tour or air taxi service, offering sightseeing flights over the Ottawa River valley and the surrounding Laurentian foothills.
It was not a major transportation hub and handled a very low volume of traffic, consisting exclusively of seaplanes.

There are no known or published plans to reopen the Fort Coulonge Water Aerodrome. Re-establishing a water aerodrome, even a private one, requires a formal process with Transport Canada. Given the likely private and small-scale nature of its previous operation, a reopening would depend entirely on a new private owner or commercial operator having the need and resources to re-certify the location, which is considered highly unlikely.
