The spring snow melt is happening and will be bumping the flows daily. The flows are jumping around 1,500 CFS daily. Over the next few weeks with the warming weather we should begin to see things happening on this great river. Keep an on the gages, it should drop in later this month. You can look forward to some big Stoneflies and PMDs later when it warms up. Keep your eyes on the report and we'll let you know when it's on!
