When you say"Hiwassee bridge" I assume that means the Hwy 58 bridge. Or is that the I-75 bridge? Anyway, I did some lookin' at the Hiwassee and it looks like a great area. When I fish riverine areas I always look for eddie areas and just above or just below bluff areas. There are a couple of those areas down stream from the Hwy 58 bridge at Jewell, Goodner and Powell bluffs. There also is an interesting feature not too far from the bridge it's self, a "stock pond" that is very near the shore but about three hundred yards from the bridge. There are also many cuts from small creeks that run through the shallow flats and fishing these where they meet the main channel and a few hundred yards back from the channel could hold lots of fish. There are also some springs that look very interesting to me. When the water gets really hot, the water coming from the springs in this area is always around 54 degrees. The fish, whether it be bass, 'gills, stripe, or catfish really love that cool water. There is a cut that comes out to the channel that is just up stream from Birchwood creek that has two springs in close proximity to one another that calls me there. I don't know how much flow comes from the springs, sometimes when there are springs on the maps it's just a trickle and sometimes the flow is enough to clear the water for a huge area, the best time to check them out is in the winter when the water's down and you can really see the difference in water color. There are also good looking switchbacks on Gunstocker creek channel that could have some great drops and stump rows. Those are the areas that look best to me. Let me know if any of that helped.
