Wyoming’s Lake DeSmet Opens To Seaplane Training

Thanks to the advocacy efforts of J.T. Grainger and Steve Guetter, local aircraft now have indefinite access to the lake.

Pilots can now obtain their single-engine seaplane (SES) rating at Lake DeSmet in Wyoming, thanks to the efforts of advocates J.T. Grainger, Wyoming field director of the Seaplane Pilots Association, and Steve Guetter, president of the Minnesota Seaplane Pilots Association.

As reported by Wipaire, a Minnesota-based manufacturer of aircraft floats, the pair met with county officials to discuss inspections before and after flights to help prevent the spread of aquatic invasive species in the 3,600-acre lake.

Grainger, who also runs Sheridan Pilots 307 Flight School, announced that local aircraft now have permanent access to the lake, while non-local aircraft can obtain access via the Seaplane Pilots Association’s mobile app. “We hope this will lead to expanded state-wide access,” Grainger noted.

Guetter’s in-person meeting was pivotal in securing ongoing approval for operations at Lake DeSmet from Johnson County officials, as he shared his firsthand experiences with effective techniques used in Minnesota to prevent seaplanes from carrying invasive species.

Additionally, the Seaplane Pilots Association listed recommendations to prevent the transfer of invasive species including:

  • Using the Department of Natural Resources website or Seaplane Association mobile app to identify bodies of infected water prior to flight.
  • Thoroughly inspecting float surfaces prior to departing a body of water.
  • Wiping down float surfaces when aircraft have remained in water overnight.
  • Pumping out water from float compartments prior to departing a body of water.
  • Visually examining water rudders and landing gear for weeds after departure.
  • Cycling rudders/landing gear over unpopulated land areas prior to landing in other bodies of water.
