Lost Lake Seaplane Base

The closure was most likely due to the cessation of private use. Seaplane bases on residential lakes like this are often designated by a single property owner for personal use. The closure would have occurred if the owner sold the property, no longer owned a floatplane, or for other personal reasons. There is no evidence to suggest it was closed for military conversion, a major accident, or significant economic reasons affecting a public facility, as it was never a major public or commercial operation.

The site is Lost Lake, a body of water surrounded by private residential properties. The lake itself is used for year-round recreation, including boating and fishing. While the official 'seaplane base' designation is closed, the lake remains physically accessible. It is possible that local residents with floatplanes may still occasionally use the lake for private takeoffs and landings, but it does not exist as a charted, public, or officially recognized aviation facility. There are no remaining signs of a formal base, such as public docks, hangars, or fueling infrastructure.

Lost Lake Seaplane Base was representative of Alaska's vital general aviation culture, particularly in the Matanuska-Susitna Borough, which has one of the highest per-capita rates of aircraft ownership in the US. Its significance was purely local, serving as a private point of departure and arrival for at least one lakefront resident. Operations would have consisted of single-engine floatplanes (e.g., Piper PA-18 Super Cub, Cessna 185/206, de Havilland Canada DHC-2 Beaver) used for personal transportation, recreation (fishing, hunting, access to remote cabins), and logistics, which is a common lifestyle in the region. It was not a commercial base and did not handle scheduled flights.

There are no known public plans or prospects to reopen Lost Lake Seaplane Base as an official, charted facility. Any future aviation use would likely be a new, private initiative by a lakefront property owner, who would need to seek the appropriate registrations with the FAA and state/local authorities. Given the established residential character of the surrounding area, the establishment of a commercial or public-use seaplane base is highly unlikely.
