Rising water on Eagle Island shut down the West Ada park until further notice on Saturday, according to a release from Idaho Department of Parks and Recreation.
Park officials told the Statesman they were escorting the 50 or so park patrons out of the area on Saturday morning after high water created potentially hazardous conditions.
"The safety of our visitors is our primary concern," said Jennifer Okerlund, IDPR communications manager, in the release. "The rising Boise River has created unsafe conditions on and alongside the park's main entrance road, forcing us to prevent access."
Gates into the park are closed, and access to the park is completely restricted.
The closure follows the evacuation of nearby Riviera Estates mobile home park, where residents were told to leave more than a week ago as water seeped into the area.
