Salmon River Conditions

Middle Fork Salmon River Flows, Snow and Water Levels, Weather Predictions, and Averages

Weather on the Main Salmon River is typically warm and sunny. The average daytime temperatures range from 70 degrees to the lower 90s, and the temperatures at night range from 45 to 70 degrees with the average rainfall per year approximately 10 inches. Temperatures and water levels can vary depending on the time of the year you plan to embark on your Idaho fly fishing trip or Salmon River whitewater rafting adventure.

Depending on snowpack and runoff, June is normally whitewater rafting time only. July brings warmer water and air temperatures and the beginning of prime dry-fly fishing, which continues through August and September. The following charts and online resources show temperature, water levels, and precipitation information for the months of March through October so that you can better plan your Solitude River Trip.

“This was my first time using dry flies. Being able to see a cutthroat come up to the surface and take the fly is a blast! The “Solitude experience” was priceless. Willi and his crew are tops.”
