Safety for Boaters
Before going out on the water, check weather forecasts and look for storm warning flags at marinas. If a storm breaks while you are out, seek shelter in a protected cove immediately and wait until the storm passes. Lightning is also a hazard on open water.
Water levels in lakes Mead and Mohave change throughout the year. Always approach the shore with caution and watch for shallows and submerged debris.
Many persons who drown never intended to enter the water. Always wear a life jacket. All boaters must have required safety equipment on board their boat.
Distances to islands, buoys, and across coves are easily underestimated. Don't overestimate your abilities. Air mattresses and other inflatables can blow away, leaving you stranded far from shore. Never rely on an inflatable device as a life jacket. Always wear a life jacket when swimming, fishing or playing in the lake.
Skiers must wear life jackets. An observer must accompany the boat operator. Display a ski flag when a skier is in the water.
The high temperatures of summer can cause heat exhaustion or even heat stroke. Avoid strenuous activities during the day. Drink plenty of water, even when you are not thirsty; your body can lose large amounts of water without you realizing it.
It can't be emphasized enough that hiking during the late spring to early fall months can be VERY DANGEROUS due to extreme heat. Please take extra precautions during this time such as delaying any hiking plans to cooler seasons. Carry extra water. Let friends or family know your plans, locations, and time of return.
Rattlesnakes, one type of scorpion, and the Gila monster are poisonous, but will leave you alone unless disturbed or cornered. Wear sturdy boots and watch where you step or place your hands.
A microscopic amoeba, Naegleria fowleri, which can live in hot springs, can cause a rare infection and sometimes death. Do not dive or submerse your head in warm springs or associated streams.
Oleander is a toxic plant common to developed areas; neither you nor your pet should eat any plant part or drink water from ditches near the oleander.
Desert thunderstorms carry the double threat of flash floods and lightning. They occur most often in summer and fall. Be wary of nearby storms. Violent downpours can cause flash flooding in distant areas untouched by rain. Never camp in a wash or other low-lying area or drive across a flooded road. Stay out of open areas where lightning may strike. Check the weather before you visit the park.
Abandoned mines and tunnels, with their deep shafts and old, rotten supporting timbers, are dangerous. Stay away from them!
