But the Ada County Sheriff's Office has issued a warning to those tempted to get their tubes out.
According to the sheriff's office, the U.S. Bureau of Reclamation plans to increase river flow to about 1,400 cubic feet per second by Wednesday afternoon. On Tuesday, flow at the Glenwood Bridge was 800 cfs.
The river should be running around 1,400 cfs until the end of May. That's when water managers are expected to reduce the flow. Flood stage is 7,000 cfs.
With cool water coming from the bottom of Lucky Peak and temperatures beginning to heat up, water worshippers may be tempted to dip in. But water temperatures are still cold, Ada County says - cold enough that Idaho Statesman Outdoors columnist Pete Zimowsky recommends against tubing.
