I know a spot that you may be able to access but not sure. Up in the Haw river there is an old submerged roadbed that crosses. I have seen alot of folks in boats fishing for cats there.
Looking on Mapquest, it looks like you could take hwy 64 to N Pea Ridge road. Turn right onto Seaforth road and where it dead ends. On Google Earth it looks like you should be able to make a short walk down the old road to the river.
