I like to fish without a guide.  That’s part of the draw of fishing to me, figuring things out.  Nothing teaches you about fish behavior better than good old trial and error.  But after years of not being a very good steelhead fisherman, my brother talked me into going on a guided trip on the Muskegon River. Having that experience made me appreciate the value of a guided trip every now and then. Here, I will share a few of  the tips I learned while bobber fishing for steelhead.

The Bobber Rig

Before we continue, it is important to remember the goal of the technique.  The goal, as with any type of fishing, is to put something that the fish believes is food in a place that the fish can see, smell or feel.   The problem with steelhead, is that they are very finnicky.  And in clear, shallow streams, it’s very bright under the water and they easily notice the slightest discrepancies between real food and bait on a hook.

Therefore, in using this technique, we must make sure that our presentation is perfect.  This means not only giving the fish something they want to eat, but making sure that the food looks normal in its environment.  In moving water, this is not as easy as it might seem.  But the tips that we learned ensured that our presentation was as good as it could possibly be.

To be clear, the techniques below won’t work if fish aren’t present.  This article will focus on the technique used to catch the fish and not on locating steelhead.  For our purposes, we will assume that you are fishing a run of water that holds fish.

1. Use a Flourocarbon Leader

Most rivers that hold steelhead tend to be clear.  And because the water is so clear, the fish tend to be extremely line-shy.  This makes a flourocarbon leader a must.

Transparent materials bend light to some degree.  A measure known as the refraction rate indicates how much the light will bend.  Flourocarbon has a refraction rate that is very close to water.  This means that it is more difficult to see under the water than any other type of fishing line.  In fact, I recommend flourocarbon when fishing any clear body of water, regardless of the target species. 

2. Keep the Bait on the Bottom

While in the river, the steelhead tend to hang out near the bottom.  This is where a lot of food tends to tumble downstream.  The length of the bobber rig we used on this guide trip was continually adjusted based on the depth of water in the run of the river that we were fishing.  The goal was to have the bait occasionally bump the bottom to assure us that the bait was where the fish were. If the bobber just twitched occasionally, we knew we had it right.  If the bobber was continually twitching and leaned forward, it was a sign that the rig was dragging on the bottom and we adjusted our length/weight until we got the twitch pattern we desired.

3. Keep Your Line Out of the Water

This was by far the most interesting thing that I learned on our trip.  Our guide was constantly monitoring our lines between the rod tip and the bobber and if that line touched the water, we heard about it.  This was one of the most important aspects of the technique and our guide said it could make the difference between a limit of fish and getting skunked. 

The reasons for his concern make sense, when you consider what is happening under the water.  In order for the bait to look natural, it must be flowing with the other debris that is flowing along the river bottom.  If the line between your rod and the bobber lays in the water, the water will pull the line (and thus your rig) downstream faster that it would go naturally. 

To better understand this, let’s take a look at the flow profile of a river or stream. 

river velocity profile

We can see that the river’s peak velocity tends to be located just below the surface, while the velocity near the river bottom is much lower. The water velocity translates into force on our fishing line.  The higher the water velocity at a given section of our line, the more force on that line.  This velocity profile pulls a bow in the line ahead of the bobber which will cause the bobber to lean back as long as the bait/weight is not dragging on the bottom.

However, if the bait is dragging the bottom (see below) the top of the bobber will tend to tilt downstream.  This is an indication that you have too much line out or too much weight on the rig. A bait that is dragging is moving too slow relative to the rest of the debris in the current and your odds of getting bit go down significantly.

The bottom line is make sure the line runs tip to bobber throughout each and every drift!

4. Use Egg Patterns During the Spawn

When approaching any fish, the key is always knowing what they want to eat.  For steelhead during the spawn, the answer is simple.  The river is full of fish eggs. There are so many fish eggs in the river, that the fish really don’t need to focus on much else.  That’s not to say that they won’t, but using egg patterns is a great first choice when fishing during the spawn. If the stretch of river you are fishing is void of eggs, you may need to switch to something else like waxworms or flies. But very often, egg patterns or spawn bags is all you will need.
