I’m no expert and I’m not familiar with the area you’re referring to but I can share what I’ve learned recently on wingdams, as far as locating them.
When traveling the main channel of the river, there are red and green channel markers. These markers are typically placed off the end of a wingdam. The dam is controlling current rate by pushing the water back toward the main channel. This push creates a definitive line across the current flow. It’s not always a bubbling, just a fine line drawn across the water surface, indicating a current disturbance. They are really visible when a south wind pushes the surface water up the current. When the south wind is absent, a trick to find them is to use your boat to “push” water at them, much like the south wind would do, and look for that line to appear. It may take more than one try so be patient with it. Until you see them clearly, it can be somewhat tricky.
Well, if you must find them alone, this should get you started. Best advice I have is to hook up with someone that has river experience, particularly in your area of interest, and go with them for a day to pick up some basic knowledge. Best of luck and good fishin’ to ya!
