A swollen Minnesota River spilled over its banks and onto the footings of three rides at Valleyfair in Shakopee. Two are made of wood.
But spokeswoman Robin Stinnett said none of the three suffered long-term damage or even needed repairs before reopening earlier this month.
"There's nothing we can do as far as pumping water out of the area," she said. "We just had to wait for the water to physically recede."
The three are outside of the protective dike that kept its other rides dry during the June floods.
All three of the rides, including the two wooden roller coasters, are built to weather standing water as well as rain.
The rides went through routine tests — normally performed on each ride daily — before opening to the public.
The rides involved were the roller coasters Excalibur and Renegade and water ride Thunder Canyon. The roller coasters opened in time for July 4th, and Thunder Canyon was splashing again by July 8.
Dennis Speigel, president and CEO of International Theme Park Services, an industry consultant in Cincinnati, said that every year a handful of parks nationwide temporarily close some or all rides due to power outages, tornadoes and other mishaps.
