I have never been to Rogers creek but it does look inviting. If I were fishing there for the first time I would be sure to hit a couple of places for sure, grass or no grass. Of course like ranman said, the up river point looks good but as you head back following the creek channel, there are a couple of switchbacks in the channel that I would fish if there was a bunch of bait there. There are some nice looking ditches out there too. The places that look most inviting to me however is where the channel sweeps accross the end of a couple of points 1/2 to 2/3 the way back to the bridge. One good swing of the channel is closer to the bridge maybe 5/6 of the way back to the bridge and it looks to be the best spot to me as on an outside bend of the channel. If there are laydowns or grass at that point, I would bet that there would be fish there. There is also a submerged island that is on an outside bend of the channel and if there is brush or grass on that hump I would bet that it would hold fish. Just looking at the maps that's where in the creek I would start. The Ledford Island area out on the main channel looks good too. If there is grass there where the current goes right past, I would expect fish there just like you found out at Hiwassee Island. Let me know if you get onto them. I love to explore new water too!
