Present, classed as rough fish.

Freshwater drum

Aplodinotus grunniens

Also called sheepshead. It crushes mollusks, so the zebra mussel invasion fed it.

What the DNR measured

Shawano Lake data: No stand-alone table in the 2023 comprehensive report.
Season: Open all year as rough fish: no minimum length, unlimited daily bag.

What that means on the water

Drum eat mollusks, and this lake now carries zebra mussels plus four other invasive snail and mussel species. They are common in the Wolf River system.

Where to find it

Fish the deep basin and the outlet channel.
Look for hard bottom next to current.

How to catch it

Crawler or cut bait on the bottom.
They hit jigs meant for walleye more often than anyone plans.

Wolf River below the dam	The spring run water, and the bank where people gather in April to watch lake sturgeon spawn. Note the closure: from April 15 to May 15 the stretch below the dam is a fish refuge and is off limits.
