Very close to where you have been is a good place. The creek the that the ramp and bridge you referred to is called Robeson creek. It is one of the deepest creeks on the river side of the lake. That whole creek is a good spot to fish. Also, as you are headed out you will see an old road on your left, the asphalt is still visible. As you enter the main river, turn left and watch both sides of that area. A few hundred yards upstream you will see where that same road crossed the main river. It is easily seen. If you turn right out of Robeson creek, you will see a tiny island a ways down on the right. Behind it is called Stinking creek, anither good spot with a HUGE shallow flat in the very back. The kiuth of Stinking creek is reportedly an awesome crappie fishing spot as well. If you continue past the island you will pass the dam (on your left) and will come to Poe's Landing, accessed via HWY US1 . It is the only ramp on the lake im aware of that you pay to use ($3.00) which is a little annoying, however, it is almost never very crowded making it worth the 3 bucks to me. If you go left when you see the dam as if you are headed out towards the main lake there are several islands on tbe left with grass banks that usually produce.
