Keith, my experiece has been that the dominant structure will hold the biggest fish in a small stream. You may have to float through, or wade through, several hundred yards of stream until you get to the ideal spot. Once there, spend some time as it may well be worth it. More often than not this dominant spot will be on an outside bend of the stream. It will often include a fallen tree, overhanging bank, or other verticle structure that the bass will relate to for shade (summer time makes this especially important as temps and light are at their max). A couple of casts with a spinner type bait won’t do as the bigger fish are deep within the structure and will not come out after the lure. All you will do is catch the more aggressive smaller fish. Use a slow approach that goes right into their “house”. Try a small jig such as a crappie tube jig or a BPS maribou jig in 1/32, 1/16, or 1/8 oz size, preferably in black or brown. Summetime is crayfish time and you need a bait that looks like the real thing. Let the current dictate the size of your jig as you want it to naturally sweep into the hole. If you are getting hung up often, especially on rocks as the jig drifts, then you are using too heavy of a jig. Expect to lose plenty of these jigs due to the stucture (wood). Fortunately, they are not very expensive. The cast should be made upstream, or at least parallel to the structure you are fishing. Let it wash into the hole as you basically do nothing except keep an eye on the line and let the jig drift with the current. This is not an easy method and you will have to get a feel of what is, and isn’t, a pick up. Positive results are BIG smallies from some of your ideal structures. Remember, do not fight these fish long as the water is warm this time of year and stress levels are at their highest levels. Bring them in and let them go. Hope this helps!!! LOL
