  • The loud barks of a few California sea lions echoed across the island this afternoon. Perhaps they are calling out for other pals to stop off here or just being loud California sea lions.

Facility work:

  • Clean windows
  • Tidy boat ramp of weeds and accumulated small pieces of wood
  • Top up water in the 24 batteries in the Energy Building
