Eligible for inclusion in the National Register of Historic Places.
In 2011 the US Fish and Wildlife Facilities Maintenance Officials spent $193,000 for estimates to repair the Seaplane Hangar. This amount included the costs to transport and house potential bidders on Midway as well as to transport and house three to four staff members from the winning bidder to conduct work necessary for developing the estimate. Plans and costs to rehabilitate/repair the seaplane hangar were finalized and contract bids were reviewed. The project was halted because of the high cost.
The historic Seaplane Hangar collapsed on January 13, 2022. It was reported that heavy winds and rain were the cause of its collapse. The Hangar was not included within any preventive maintenance program by the US Fish and Wildlife Service, over the past 20+ years.
