Forget the liver, stick to big fat dew worms on a single hook. Like Dago said, heavy tackle is recommended. His advice may seem like overkill however it is only a matter of time until someone tops 100lbs
If you are onshore and you hook into one of the monsters, you will be wishing for the big stuff. The river is high & dirty (and rising) right now, but remember that sturgeon are scent predators, so water clarity is a moot point. Study the channel, and look for slacker water out of the main current & close to deep holes.
TIGHT LINES !!!
