A state of emergency is in effect in St. Paul where the river is expected to rise another foot before cresting on Saturday, prompting the closure of several roads, trails and parks, including most of Harriet Island.
With water filling the Wigington Pavilion at the popular downtown park, the city has canceled 11 events at the shelter, including graduation parties, family picnics and one company picnic through July 7, said spokeswoman Clare Cloyd.
Surprisingly, no weddings were scheduled this weekend or next, she said.
Picnic permits for the Crosby Farm Regional Park picnic shelter have also been canceled, Cloyd said.
Meanwhile, high water on the Minnesota River has forced Valleyfair to shut down three rides, shorten park hours and cancel July 4 fireworks.
The amusement park will be open from 10 a.m. to 9 p.m. daily until water recedes and its waterpark, Soak City, will be open only 11 a.m. to 7 p.m. daily, Valleyfair said Friday in an email.
The Mississippi River was expected to reach 20.8 feet in the downtown St. Paul area before water levels drop, the National Weather Service said. If that mark is reached, it would be the seventh-highest crest ever. Flooding begins when the river reaches 14 feet.

With damage expected, the St. Paul City Council on Wednesday passed a resolution declaring the emergency, allowing the city to seek county, state and federal resources.
