Ice Safety: Ice is Never 100% Safe! — Do not judge ice safety on thickness alone. Ice does not form or maintain a uniform thickness. Snow, wind, slush, temperature, and other factors can cause ice thickness and strength to vary greatly, even within inches. Recreate on ice at your own risk and verify ice thickness as you head out. Click here to learn more ice safety tips.


Insects: During warm months, insects are present on the island and emerge at different times.

  • Biting gnats (no-see-ums) not currently active emerge in the spring (April – June).  These are very tiny biting flies. Insect repellent is ineffective against the gnats; fine-mesh head nets are recommended.
  • Midges not currently active are non-biting flies that form columns along the causeway mid-spring through early fall. These are what cover your windshield while driving to and from the island.
  • Mosquitoes not currently active are present from mid- spring through early fall. Insect repellent is effective. Note: West Nile Virus has been found in Davis County.
  • Brine Flies not currently active are non-biting flies that cover the shorelines and occasionally move onto land early-summer through fall. These flies are harmless and move out of the way when approached.
