Fished it today with a few other guys on the ice. Ice was 4"- 5" in the holes I drilled straight out from ramp 100 yards out. Most guys stuck to that distance with open water toward center. The ice was cracking and moaning all morning. We caught a few bass and small perch, not much action.
Be careful, I was told the ice thickness gets thin if you venture to far out from launch area.
