I think the highest temperature we’ve seen in the past 4 days might be 2F.  With temperatures well into the negatives and a max low around -20F, our once flowing river is now mostly slush and ice.  Granted we are still open on the upper 4-5 miles, floating is no longer an option and the river is locked up solid below Government Bridge.  If your thinking about going out use caution and don’t forget to let your equipment sit outside for awhile before you use it…if you take it from a warm vehicle and/or house and start fishing…well, your asking for a broken rod(heat to extreme cold makes for a brittle rod-expanding/contracting of rod materials).
