As of 1900, Knox County was entirely organized.The dissolutions of the town of Hurricane Isle (1915), Muscle Ridge Plantation (1916) and Criehaven Plantation (1925) all created unorganized territory, however, as each reverted to that state.The former territories of Hurricane Isle and Muscle Ridge were later annexed to nearby towns, leaving only Criehaven as unorganized territory today (see the Notes section for more information).
