Lac Kaiagamac Seaplane Base

The closure was due to operational and economic reasons. The seaplane base primarily served local outfitters, most notably the Pourvoirie Club Hosanna on Lac Kaiagamac. The most probable reason for its closure is a shift in business models, such as the outfitter no longer requiring or offering dedicated fly-in packages, likely influenced by improved road access to the lodge. There is no evidence of closure due to a major accident, military conversion, or environmental concerns.

The physical site is the water surface of Lac Kaiagamac. The designation CA-1129 is no longer active, meaning it is not a registered or charted aerodrome. The land adjacent to the former base's coordinates is occupied by the Pourvoirie Club Hosanna, a hunting and fishing lodge that is now primarily accessed via a gravel road (Chemin du Club Hosanna). While the official seaplane base is closed, the lake itself remains physically accessible to seaplanes capable of landing on water, subject to Canadian Aviation Regulations.

The Lac Kaiagamac Seaplane Base was a logistical hub of local importance, characteristic of many small water aerodromes in the Canadian wilderness. Its primary function was to provide air access for tourists, hunters, and fishermen to the remote Lac Kaiagamac, located within the Zec des Nymphes controlled harvesting zone in Quebec. It facilitated the operations of local outfitters by flying in guests and supplies. Operations were seasonal and would have involved light floatplanes typical of Canadian bush flying, such as the de Havilland Canada DHC-2 Beaver and various Cessna models (185, 206) on floats. Its significance lies in its role within Quebec's nature tourism and outfitting industry.

There are no known plans or prospects to formally reopen or re-register the Lac Kaiagamac Seaplane Base. The primary need for a dedicated, charted water aerodrome at this location is minimal due to reliable road access to the local outfitter. Any future seaplane traffic would likely be occasional and operate on an ad-hoc basis without the need for a formal base designation. Therefore, the prospect of reopening is considered to be virtually zero.
