Night time lows 53-56 degrees.
This past weeks= Blue skies, wind, warming temperatures

It was pretty pleasant over the Fourth of July, with some mild temperatures. Basically in the 80s during the days, and down to the mid-fifties in the evenings...perfect for on-river camping.

As reported, everything seems to be running behind this year, including the really hot weather and Cicadas action. We've had some rain, so make sure you come prepared with raingear if you come up here.

Forecast for now thru July 11 is nice weather and little chance for precipitation, with temps cooling somewhat over the weekend with 30% chance of rain through Tuesday the 18th...then maybe drying up and warming.

Oh yes, bring some spf50 sun screen along with your rain gear along just in case. We can have the nice pm showers we used to, but we also can have big downpours early in the summer as well.

DRESS PROPERLY! Don't foget your wet weather gear. Proper clothing allows you to maintain a good attitude and helps insure that you endure even the most diverse weather situations. To deal with every weather possibility, bring layered clothing to supplement your wet weather gear.

MONTH WATER AIR CONDITIONS

January 42 34 Cold air. Cold Water. Quiet. But good flyfishing can be had with midges.

February 40 37 Brrrr! Try flyfishing the first few miles just below dam where water is warmest. Don't forget the handwarmers!

March 41 46 Things start to warm up with spring hatches. Streamers sometimes surprise!

April 42 56 Fish getting more active now as days get longer, but the weather also surprises now! Be prepared...for both bad weather and great flyfishing.

May 45 70 Nice weather, some great flyfishing. Snowpack melting, but BOR started heavy water releases last month in anticipation, so the fish are well acclimated.

June 52 80 Really enjoyable weather, lots of different "bugs" to choose from. If you can't decide, hire a guide...they've figured it out! Usually June gives us a great Cicadas showing...incredible!

July 56 85 "Early to rise" is the word in summer...if you want to get the fish! Evenings are great too!

August 58 84 Take off those waders! Wade wet! Oh, did we mention all those noisy rafters having too much fun?

September 56 70 Indian summer...most beautiful time of year! Thin crowds. Thick fall hatches.

October 54 59 Crisp autumn air. Predatory big Brown Trout fall for some big hatches.

November 49 46 Expect snow in November, but also expect some of the best flyfishing!

December 44 37 Flyfishing still good, but winding down. Good time to stay home and tie flys to give as presents!
