Lower Lake Michigan – the area ringed by Illinois, Indiana, and parts of southern Michigan and Wisconsin – is full of shipwrecks and other sunken historical treasures. The knowledge of the wrecks’ histories, survey records for preservation purposes, what actions can be taken to recover artifacts and create new documentation, etc., is spread widely across the Lake Michigan dive community. The Wrecker’s Report is a new reference document that compiles federal, state, county, and city laws to assist divers in planning shipwreck diving expeditions.
