Little River has been under going a renovation the last two years. The gills are supposed to be 7 inches and the walleyes 6 to 9 inches. Should be good fishing again in a couple of years.
I live in Moline, so I'm right here with you.
Among the other areas you mentioned, don't sleep on the LeClaire Canal. There are some really nice Crappie back in there.
It's pretty safe right now and actually about just right. The other day when I was out I launched out of rock creek just south of Clinton.
