Love to hunt rivers
Set up in a eddie or oxbow out of the main current
Set your decoys so that they will not tangle
As the current moves them around

Depending on the current
You may need more weight
I run 4 oz decoy weights in the marsh and 12 oz or more in the river and Lake Erie ( 3'+ waves )

Not sure about the local reg's
But in Ohio you need land owner permission to anchor your boat or decoys , unless you are out in the middle of the bay

Otherwise you are tresspassing , it is OK to anchor and fish LOL

So check before you hunt
