Spring Fly Fishing on the Henry's Fork of the Snake River in Idaho.

Three Rivers Ranch guide Todd Allen with Peggy P., spring fly-fishing on the Henry's Fork of the Snake River in Idaho. Peggy sent in this picture in and said, "It was a great day, especially for me. I don't think I have caught that many fish in one day over 20 inches anywhere, excluding Alaska, but then that doesn't really count."

The lower section of the Henry's Fork has been fishing good. The stretch from Ashton Dam below Vernon Bridge is currently closed until memorial day and the confluence of Fall River at Chester Dam is dirty due to runoff. Right now you can try a Blue Winged Olive, Midge, or a Streamer. The Caddis and March Browns are right around the corner!

What does CFS mean? Fly Fishing the Henry's Fork & South Fork of the Snake in Idaho.

Now that spring is underway, many river systems are facing spring runoff.  You will probably hear or read about the term “CFS”.  You might hear something like, “The Henry’s Fork dropped 300 CFS.”  or “The South Fork of the Snake has been running at 14000 CFS for the last week.”  So what does CFS mean and why is it important for fly-fishing?

CFS literally means Cubic Feet per Second.  It is a unit of measurement for moving water.  If you are standing still on the edge of a river, one CFS would be a box 12” x 12” x 12” (or the size of a basketball) moving by you every second. 

If you’re about to go fly-fish the Henry’s Fork, you check the Orvis Fishing Report and see that it is at 2750 CFS, sounds good right?  It depends.  If the flows have been steady for several days, it is good; however, it might be bad for fishing if the flows change 300 CFS everyday for the last week.  Dramatic stream flow changes tend to push fish around and also changes the consistency of hatches.  The best thing to look for is a steady and consistent CFS stream flow.   Some river systems are dependent on a managed dam; some free flowing rivers are dependent on how rapid snow melts in the high country or how much rainfall occurs.  Either way, each river is unique and is affected by CFS differently.  Next time you’re looking to go fishing, give a look at what is happening with your rivers CFS.
