Its been many years since I actually fished it but you could try the Rum River in between Ogechie and Shakopee. When I fished it, people would fish right below Buckmore Dam (which is no longer there) and catch a mixed bag of fish. Ogechie itself probably isn’t worth trying. My guess is that its choked out with rice and weeds.
I’m not sure if its an option anymore either, but you could go way up where the water comes out of Vineland Bay into the Rum too, kind of near the hwy 169 bridge. I think there’s a rocky spillover there and might be some moving water in there worth a shot.
I wouldn’t waste time with any of the ponds.
