I've fished Blood River for crappie 2 times in the past couple weeks but can't really help you with the bluegill(caught a couple by accident, but were small). The crappie I've caught have been in 15-18 ft of water slow trolling minnows(tried jigs but they seem to like minnows on a plain hook better in warmer water). Caught fish up to about 13" but haven't just burned them up(but I'm far from an expert). Had 7 keepers one morning and only 3 the other(day after storms, high pressure/cold front). Hope this helps, good luck and have fun, I'm jealous I have to work the next 3 nights and probably won't get to go again for a week.
