It occurred to me that I have never mentioned CFS before. CFS stands for cubic feet per second. It is a very simple thing, but CFS is very important aspect of my fishing preparation.
The United States Geological Survey (USGS), https://www.usgs.gov, has put flow meters in many of the main rivers and tributaries within American watersheds. I personally use check these almost every week for my local waters to get a good feel for how healthy the streams look. Add in my prior experiences, and I can estimate whether or not a particular day will be easy or hard to fish.
This past week, we had so much rain, I thought my local waters would be unfishable. Driving an hour, only to find out a river is blown out, is not my idea of fun. So I went to the website to check the CFS, and here is what I found:
Notice the flow peaked on 10th, and then had another peak on the 11th. This was due to the rain storms we had. Fortunately for me, the river recovered very quickly, and by the 13th, it was ready to be fished again. Some of the best fishing I have experience has been during the downward progression about 10-20 CFS above average,
Without this tool, I would have decided not to fish this weekend. Even though it is slightly above average, this looks very fishable to me, but I will let you know how it goes.
If you are not using the USGS water flow readings, maybe it’s time to start. You can easily enter a google search with your river name and the words USGS and CFS. And if you really want to improve your “fly fishing IQ”, keep track of which water levels produce the most amounts of fish at certain times of the year and maybe you will be able to duplicate your successful days.
Every year from starting in late July through the end of August, I head out to Wisconsin’s Rush River to fly fish during the Trico hatch. This amazing hatch can be brilliant when you catch it right. Thousands of small insects (smaller than 1/2 a finger nail) flit about in the air, mating and then becoming part of the great circle of life.
Eager trout start rising everywhere like water boiling. It is quite a scene to witness. However, fun and frustration are two adjectives that quickly blur together while fishing. Due to the tremendous amount of available food on the top water, my fly offering is more likely to be taken randomly than due to my own skill level.
With that in mind, over the years I’ve developed some techniques that seem to work well for me:
- Stay low and quiet. This is true for all fly fishing, but even more so for this hatch.
- Start with nothing bigger than 5x tippet. If 5x isn’t working, go to 6x tippet. If 6x isn’t working, then go to 7x tippet. There’s a company that makes 8x tippet . . . (http://www.shop.trouthunt.com)
- Keep your leader long, at least 12 – 15 feet.
- Size 22 flies are NOT too small. In fact, they may be too big.
- There are actually quite a variety of tricos in the air, so grab some out of the air and find your best approximation.
- Don’t be afraid to drop something really small off that trico, like a size 22 emerger with a little sparkle in it. Sometimes, a smart trout will take that offering to conserve energy.
- If you are targeting rising fish, as opposed to prospecting, then try to time your cast to land in the feeding lane when you think the trout will be ready to eat again.
- Have fun, try not to get frustrated, and change your setup frequently until you find what the trout are looking for.
I’m off to the Rush River tomorrow to go after one of my favorite hatches. What’s your favorite fly hatch?
Maybe I’ll get one of these colorful brook trout tomorrow . . .
When I moved to Minnesota, I started fishing the Kinnickinnic River in River Falls, Wisconsin (the Kinni, as the locals call her). This is a typical Midwest small to medium stream in the heart of the northern driftless area with beautiful, naturally reproducing brown and brook trout. It wasn’t until after a couple years of exploring the Kinni that I realized there was another gem about 15-30 minutes further east called the Rush River. From Baldwin all the way through Martel and Ellsworth, the Rush River winds through beautiful farmland with ample natural trout and seasonal hatches. In particular, the Trico hatch, BWOs and Sulfurs are very healthy hatches on this river at various times. Both the Kinni and the Rush are subject to large changes in water flow following rain storms and showers. This brings me to the point of this post.
A lot of fishermen shy away after a rain storm, but I’ve found that sometimes I can have a wonderful day on the river after a storm with a little strategy and the right flies. After the most recent Minnesota and Wisconsin deluge, I decided it was time to put thoughts into action. The river was running higher than usual, and was fairly ruddy, but it was not dangerous to wade (I hear my dad in my mind saying “safety first Michael!”). At the first hole I went too, I struck out big time, including losing my whole rig within five casts. Not the epic night I was hoping for. However, after adjusting my rig a little, I started catching fish after fish as I went upstream from hole to hole, with virtually no one else on the river (ostensibly scared off by the recent storm). After all, the fish do have to eat, regardless of the weather. I was already into double digits for the night, and then the fishing got relatively quiet. The biggest trout I had released so far was 10 inches (with a range of fish caught from 4 inches to 10 inches, both brookies and browns). I had about a quarter mile walk back to the car, so I figured I would tie on a Stimulator and hit the same pools and riffles on the way back. On my way back, I noticed a section of river I had previously ignored because it was difficult to get too, but the storm had padded down all the grass and made access much easier. No sooner had I made a few casts then I was doing my best to pull in a nice 15 inch brown, which is more of a rarity on the Rush. This was a fun fish to land on my newly minted Helios-2 (4-Weight) with CFO reel; this was really the first fish to challenge this rod. A lot of people shy away from Orvis for a variety of reasons, but Orvis makes fantastic gear, is committed to environmental conservation and their customer service is superb in my experience. I have products from Orvis that are over 20 years old, so I am a loyal customer. I released this brown, as I do all my fish, counted my blessings and continued my walk back to the car, grinning from ear to ear about the last fish of the night.
Caught this beauty on the Rush River before dark after a stormy couple days.
