Clark County Public Works closed areas of Daybreak Regional Park due to significant erosion and loss of bank-stabilizing trees on the riverbank of the East Fork Lewis River.
The county is installing fencing around the closed area, according to a news release. Signs will alert visitors to the closure. There is no reopening date.
Officials warn people to never enter closed areas. High water and swift currents are common in the winter months, the news release said, and can damage banks and make them unsafe.
Cold, fast-moving water is especially dangerous, the agency said, and banks might be unstable even after high water levels have receded.
