You are doing really well! The trout here seem to be rather spooky since the water is reasonably clear (for Iowa)...and while most that are caught get hooked near shore, a long cast down along the shoreline usually gets the most fish. I don't think a Tenkara rod would work well here, but I'm sure it would be FUN!
Wind is really strong here today, and is supposed to switch directions 90 degrees this afternoon, plus the air temperature is going to drop 35 degrees by around 6pm this evening. That kind of foils my plan to fish this evening!
