I just went there saturday night and ran upriver about 10-15 miles, we didnt catch anything but I am almost positive that they are there, if you keep looking on your left as your coming out of glenburnie going upriver through the channel there is a lillie pad bed about 400 yds long we didnt try fishing there but I can almost bet that there is flats sitting along the edge waiting for baitfish to run in and out of those lillies, and I know there are bluegill in there because we caught some for bait as we were coming through. Hope this helps, Jason
