💦 Anchorage’s H2Oasis Waterpark Still Closed, Inspections Push Timeline Into Fall and Beyond

ANCHORAGE, Alaska (Sept. 21, 2025) — Anchorage’s only indoor waterpark remains shuttered as repairs and municipal inspections continue into the fall, its owner confirmed in a phone conversation this week.

This afternoon, H2Oasis Waterpark owner Dennis Prendeville told Headline Living the facility at 1520 O’Malley Road is undergoing ongoing maintenance and is waiting for inspections from the Municipality of Anchorage before reopening. The timeline now points to October or later, depending on how those inspections proceed.

The tropical-themed attraction, home to towering water slides, a wave pool and a lazy river, has been closed since September 2024 for what was initially described as extended maintenance.

Permit filings unclear

A review of public permit and inspection databases shows past activity at the property but no obvious new large-scale filings posted in 2024 or 2025.

• Municipality of Anchorage’s permitting system lists historical trade permits — plumbing, fire and mechanical — tied to the property in prior years.
• Environmental Health Services, which oversees pools and public facilities, hosts inspection records in its EnvisionConnect/Accela portal, but no recent entries for H2Oasis were visible.
• Monthly permit activity reports on the city’s website did not list a new commercial building or major alteration permit for the waterpark during the past year.

City officials note that pool operations typically require approvals for HVAC, water filtration, plumbing and safety systems. Without clearance, facilities like H2Oasis cannot legally reopen.

Community speculation

The waterpark’s official website and Facebook page continue to display closure notices. On local forums such as Reddit, some residents have speculated about the duration of the shutdown, though municipal records remain the most reliable source for any reopening timeline.

What comes next

Anchorage families eager for the return of their only year-round tropical escape may be waiting at least a few more weeks. The park’s reopening ultimately depends on passing city inspections. Until then, H2Oasis remains closed.
