The timing of increased water releases from Folsom Lake has been moved up and is expected to reach 15,000 cubic feet per second by 3:30 p.m. Wednesday, according to the Sacramento Fire Department.
The release will cause the American River to run higher and faster than normal.
Due to rising river levels, Sacramento County officials announced that Discovery Park, along with the Howe Avenue access point and miles 0 to 3 on the American River Parkway bike trail, are closed through Monday morning.
Sacramento city and county departments, along with other agencies, have been working to notify people along the river about the potential for rising water. Because of the changing nature of the river, officials advise people to use caution around area waterways and to stay on high ground.
