Gianni, I know exactly what you mean. Last spring when I lived in Independence, Ia I was fishing the second damn at Quasqueton. I had just caught a few nice walleye in front of 15 or so people whom were all fishing up above at the first damn. I tried hiding the fact that I was catching some fish by unhooking the fish in or right near the water. It didn’t work. They asked how the fishing was down here and I said fine. The next thing I knew was that there were two guys standing 2 feet away from me fishing the same spot I was. Then one of the guys even had the guts to wade out into the water right where I had just caught my last fish. That was enough for me. I packed up my gear and poles and headed for another spot.
I have had excellent luck on the Wapsi and the Cedar. Anywhere from Waverly to Cedar Falls on the Cedar and anywhere from Littleton to Troy Mills on the Wapsi. Right after ice out in the spring (if it ever does ice up this year) is when you want to start. Something I learned form fishing the Wapsi though is when the Buffalo Carp start showing up all over the place (you’ll know when they do) mainly at the damns, the walleye will no longer be there. This usually occurs within the first 5 weeks after ice out. You will however start catching some nice bass and pike.
Hope this helps
