One can use a vehicle to drive around Lake Michigan, an airplane, or a boat.
One week?
Sailing yachts have the anchor at the bow of the boat.
Boat rental on Lake Michigan is variably priced depending on which company the individual decides to rent from. Currently, such a service can be purchased for as low as $299 for a one day rental, although that price is subject to change.
Move the boat directly over the anchor
According to the Navigation Rules, a rapidly ringing bell every minute signals a boat at anchor in the fog.
There are vessels designed to to specifically anchor from the stern of the vessel. However if you mean a "fishing boat" as a small recreational or "pleasure" craft like a bass boat, it is almost NEVER recommended to anchor from the transom of a boat. This is especially true if you have any type of current or sea state (even lake or wind waves) as your stern is the lowest part of the boat to the waterline and swamping can happen fast. I have personally seen it at the mouth of the Columbia River bar located in Pacific Northwest. Not to mention you run the risk of fouling your props with the anchor rode.
It would die. It is generally a salt water mammal and that is a fresh water lake. It could be killed by the boat traffic.
