Water

  • Island Mine Stream: Running.
  • No algal blooms have been reported at this time.

  • Suspected blooms are tested for toxin levels and monitored when possible. Given the consistently low toxin levels of blooms on Isle Royale, water quality safety guidance has been updated:

    • It is not recommended to filter water in any areas where there is surface scum, strong odors, or other evidence of a significant bloom.

    • Blooms move around depending on wind and rain – filter water from places where blooms are not present or a different water source.

    • It is low risk to filter water from relatively clear areas of an impacted water source.

Wildlife
