A Dubuque Rig is a 3-way rig with a jig for the drop weight instead of a sinker. I fish DBQ Rigs quite a bit and I catch many fish on the drop jig. With the lower current now you can get by with as light as a 1/2 ounce drop jig. I use jigs from 1-1/2 ounce to 3/8 ounce for my drop jigs depending on the current.
One thing that I’ve learned about Dubuque rigs at least for MN residents, is that you can only use one rod with it on it and it is only legal on the border waters.
