VFR *should* use a "lake crossing flight plan"(if they are still
available) which is filed in conjunction with a VFR flight plan. The
Lake crossing portion is activated coming up on the shore. You are
expected to provided the time for "mid point" and you have a 5 minute
window in which you *must* call ATC at the mid point, or you are going
to receive a very expensive bill for SAR. At midpoint IIRC you are
requested for the ETA at the shore line and again call ATC.

I'm not familiar with the lake, so I was just going to ask about the
availability of such a service.

A VFR service is offered in the Cape Cod, Islands, and Long Island
area that works similar to what you describe, with position reporting.
