State authorities have temporarily closed the Smith River due to ice jams, according to the Helena Independent.
According to the paper:
Montana Fish, Wildlife & Parks has temporarily closed the Smith River to floating due to ice jams.
In a rule certified Tuesday by the secretary of state’s office, FWP says river conditions pose a danger to recreationists.
“There are intermittent ice jams on the Smith River that have caused the river to be impassable by recreationists. The steep canyon walls provide a perfect place for ice to collect and remain due to lack of sun exposure,” the closure notice states.
