Bring polarized sunglasses to better spot fish and aquatic life in the clear lake shallows.
Wear insect repellent if visiting during dusk or dawn, as island locations often have higher mosquito activity.
Utilize the designated fishing pier rather than the shoreline for the most stable footing.
Do not attempt to swim in areas not designated for water sports, as lake conditions near the island can change.
Park access may be restricted during winter months due to ice and snow conditions on the causeway.
Carry-in, carry-out trash policy applies; keep dogs on a leash at all times.
