Re: In California? Maybe
The exclusive economic zone is 200mi so 80km is well within that for California let alone the islands.
According to the wiki that rules them all this zone is mistaken as or at least used to be known as the territorial waters. In any case it still gives the "owner" certain rights, economic ones as you might expect which IMO would include things such as a wreck.
Read the wiki, it's quite informative http://en.wikipedia.org/wiki/Territorial_waters
