LAKE DELTON, Wis. (WFRV/AP) — A popular Wisconsin Dells attraction will remain closed for the rest of the season after two employees tested positive for the coronavirus.

Noah’s Ark Waterpark announced Wednesday that it has decided to keep the park closed for the rest of the 2020 season.

“We made this decision proactively with the health and safety of our Guests, Team Members, and the Wisconsin Dells community as our top priority.”

“We thank our Team Members for their flexibility and tireless efforts to provide people with a fun escape during this unprecedented summer. To our Guests: thank you for your understanding and support during these challenging times.”

All 2020 single-day tickets can be used next summer, and 2020 season passes will be extended to include the 2021 season.

Noah’s Ark opened for the season on Saturday, June 20, with new safety measures, including limiting capacity and pre-entry temperature checks.

On August 1, Noah’s Ark announced a temporary closure after two team members tested positive for coronavirus. At the time, the waterpark said:

“The park will undergo a thorough cleaning and sanitization today, and will be closed until further notice. We will provide more information on reopening as soon as possible.”

Noah’s Ark is scheduled to open its 2021 season on Memorial Day weekend.
