Airport Closure Information

Last updated: Jul 27, 2025
Closure Date

Circa June 9, 2008

Reason for Closure

The seaplane base ceased operations due to a natural disaster. On June 9, 2008, after a period of intense rain, the dam containing Lake Delton was breached, causing the entire 267-acre lake to drain into the nearby Wisconsin River in a matter of hours. This event completely eliminated the 'runway' and operational area for the seaplane base. Although the lake was refilled by Memorial Day 2009, the base never reopened, likely due to the economic devastation, the cost of re-establishing the business, and the subsequent redevelopment of the associated shoreline property.

Current Status

The site of the former seaplane base is now simply the water surface of the restored Lake Delton. The adjacent land, where the associated Medo's Resort was located, has been redeveloped. The shoreline at the given coordinates is now occupied by private residences and the Delton Oaks Resort Condominiums. There is no remaining infrastructure—such as a dedicated hangar, ramp, or marked docking area—to indicate that a seaplane base ever existed there. The lake is used extensively for private and public recreational activities like boating, fishing, and water skiing.

Historical Significance

The Medos Lake Delton Seaplane Base was a small, privately-owned facility associated with the local Medo's Resort. Its primary operation was providing sightseeing flights for tourists over the Wisconsin Dells area, which is famous for its scenic river gorges and attractions. The seaplane offered a unique aerial perspective, complementing the well-known 'Duck' tours and riverboats. It was a distinctive feature of the area's mid-to-late 20th-century tourism landscape, catering to visitors seeking a novel experience. The operation was small-scale, likely consisting of a single aircraft operating from a dock at the resort.

Reopening Prospects

There are no known plans or prospects for reopening the Medos Lake Delton Seaplane Base or establishing any new commercial seaplane operation on Lake Delton. The lake is now a heavily developed residential and recreational area. Any proposal to reintroduce seaplane traffic would likely face significant regulatory hurdles from the FAA and local authorities, as well as potential opposition from lakeside property owners concerned about noise, safety, and interference with other recreational activities.
