Toxicity appeared first within and near Casco Bay, then extended to near Penobscot Bay as well as south of Casco Bay. Toxicity was fairly early in eastern Maine (closures in May and June). The coast of New Hampshire was closed in mid-May. Closures on the south shore of Massachusetts occurred in late May. The area between Gloucester, Mass. and the New Hampshire border was not closed - a bit unusual since there was toxicity to the north and the south of that area.
