VIDEO: We've got a mini heat wave later this week, and a lot of people may want to hit the Boise River.
With water coming out of Lucky Peak, the river is running fast and cold. It's only about 40 degrees in there. And right now, firefighters warn it's just too dangerous.
"The river water is extremely cold," said Special Operations Division Chief Paul Roberts with Boise Fire.
Boise's fire rescue crew out on the river today, training for the floating season. "We haven't seen this kind of current for a number of years," Roberts said.
It could be deadly even for experienced swimmers. Roberts says now is not the time for floating or paddle boarding.
"That cold water can significantly impact even the best of swimmers that are out there," Roberts said. There's also a lot of debris and other hazards they need to clear out before the float season begins.
Across the state, it's already been a busy season for search and rescue crews.
