"Fishing at Harrington Beach State Park
Surf fishing for salmon and trout draws visitors to Harrington Beach and Lake Michigan. A fishing license and a Great Lakes Salmon and Trout Stamp, available at local hardware stores and other outlets, are required for anglers between 16 and 65 years of age.
Anglers also will enjoy fishing from the shore of the 26-acre Quarry Lake.
People can catch trout, crappies, bluegills, and other panfish in Puckett’s Pond.

I'd recommend that you ask specifically about whether you are allowed to ice fish. Wading and swimming are forbidden and will get you a nice fine. However ice fishing is not mentioned on the signs. Pay attention also to the Urban Fishing signs concerning size and possession limits. If you call Andy, I'm sure he will be very helpful. He's a nice guy. Ask if you need a just a Trout Stamp - you shouldn't need a Salmon Stamp to fish the Quarry or Puckett's Pond (the smaller pond in the middle of the park). If you go up there, ask if you can tour the campground.

I was fly fishing and found that there weren't many good casting lanes for a fly rod there. Too bad you can't take a boat out on the lake.
Some other folks fishing with spinning equipment caught some 10-12" rainbow trout at about 25' deep. I think they were just using worms, but I'm not positive.
I'd bet there are some nice fish in the depths of the lake, but with no boating allowed, it might be hard to get to many of 'em.
