Cold Water Immersion and Shock Prevention

  • Don’t enter the water if it’s too cold. The average body temperature is 98.6 degrees Fahrenheit. The average pool temperature is 84 to 86 degrees. Some of California’s rivers are currently running at temperatures between 30 to 40 degrees. Such cold temperatures can literally take your breath away. 
  • Cold-water immersion is dangerous. Not wearing a life jacket while recreating in cold water makes it even more perilous.
  • Jumping into cold water can cause many life-threatening effects, including:
    • An involuntary gasp for air when you’re under water which can lead to panic and start the drowning process. It can even trigger cardiac arrest, temporary paralysis and hypothermia.
    • Cold water entering the ear canal can cause vertigo and disorientation. This may confuse swimmers, causing them to venture deeper into the water.
    • Reduces body heat 25 to 30 times faster than air does at the same temperature, and causes impairment that can lead to fatalities.
  • Below are some other do’s and don’ts for cold water immersion:
    • Do control breathing, don’t gasp. A sudden unexpected fall into cold water causes an involuntary gasp (or torso) reflex. It takes less than ½ cup of water in a person’s lungs to drown. When someone remains calm, they have a greater chance of self-rescue.
    • Don’t panic if you fall into the water. Stay afloat with the help of a life jacket, regain control of breathing, and keep head above water in view of rescuers. If possible, look for ways to increase buoyancy. If in the water with others, huddle together with everyone facing inwards to help everyone stay afloat and keep warm.
    • Don’t apply heat to extremities like arms and legs of a rescued victims. This sudden change in temperature could cause cardiac arrest.
    • Do make sure everyone is wearing a properly-fitted life jacket. Life jackets that are too big will ride up around your face. It it’s too small, it will not be able to keep your body afloat. Life jackets designed for adults will not work for children.

Wear a Life Jacket

  • Conditions change quickly in open water and even the best swimmers can misjudge the water and their skills when boating or swimming. Wearing a properly fitted Coast Guard-approved life jacket can increase survival time.
  • A life jacket can also provide some thermal protection against the onset of cold water shock and keep you afloat until someone else can rescue you.
  • Correct life jacket use:
    • Coast Guard-Approved: All life jackets approved for use by the Coast Guard will have an approval number located on the inside label. Only approved life jackets should be used on the water, and boaters may be cited for lacking proper equipment.
    • Proper Fit: Life jacket sizes come with weight or chest measurements, and should fit snug rather than purchased to allow a wearer to “grow into.” A small life jacket may not provide enough flotation to keep a person afloat. One that is too large can slip off upon entry into the water or could ride up around the face and obstruct breathing.
    • Intended Boating Activity: Always check the life jacket label to ensure it is approved for the intended boating activity.
    • Good Condition: Check the life jacket before using to ensure it is in good condition. Jackets with rips, tears, mildew, loose or missing straps, frayed webbing, broken zippers or buckles, hardened stuffing or faded label instructions lose their strength and buoyancy and must be replaced.
  • Need a life jacket? Many locations across the state allow you to borrow a lifejacket for the day or weekend. View Loaner Stations

Whitewater Rafting and Paddling

  • Most California rivers are fed by the mountain snowpack, so they are cold year around. Even on warm, sunny days, rafters and paddlers must be prepared to deal with the water temperatures. The dangers increase as water temperatures decrease below normal body temperature.
  • Using pool toys in open water, lakes and rivers is dangerous. They may be made to resemble canoes or whitewater rafts, but they are often made of thin plastic, are easily punctured and usually have only one air inlet. Pool toys are not made for navigation and are difficult to maneuver and steer.
  • DBW offers whitewater enthusiasts informative safety videos online. The dangers of high, fast and cold water safety.

Know your Limits

  • Swimming in open water is more difficult than in a swimming pool – people tire more quickly and can get into trouble.
  • Many unseen obstacles can be lurking below the water’s surface - this is especially the case with this year’s high runoff following years of drought. Drought-stricken forests and storm-driven landslides have filled rivers with submerged trees and rocks. Swift water can make these obstacles even more treacherous. DBW recommends guided trips for inexperienced paddlers.

 Parental Supervision

  • Actively supervise children in and around open bodies of water, giving them your undivided attention. Do not assume that someone is watching them. Appoint a designated “water watcher,” taking turns with other adults. Let the children know who is the designated “water watcher”.
  • Teach children that swimming in open water is not the same as swimming in a pool: they need to be aware of uneven surfaces, river currents, ocean undertow and changing weather.

File A Float Plan

  • Do file a float plan with someone trusted that includes details about the trip – e.g. launch area, marina, boat, passengers, towing or trailer vehicle, communication equipment and emergency contacts.

Check Road Conditions and Site Destination Availability

  • Visitors may experience some limited closures to facilities, trails, roads, campgrounds, etc. as department staff work to repair damage from the winter storms. 
  • Visitors are advised to call their destinations ahead of time or visit California State Park’s webpage for availability. Road conditions and driving tips can be viewed online on Caltran’s website.

Check the Weather

  • Check both your destination's and your route's weather conditions before you leave.
  • Make sure your equipment is appropriate for the weather expected. Remember spring is known for cool mornings, warm afternoons and cool evenings – wear layers.
  • If heading to the snow, take tire chains.  

Hiking Safety

  • Use the “buddy system” – hike with a friend or family member.
  • Drink and carry plenty of water (a minimum of 1 quart every 2 hours).
  • Wear sturdy comfortable shoes to help prevent injury.
  • Tell a responsible person back at camp or at home where you are going and when you plan on returning.
  • Stay on established trails. Do not walk off-trail or enter closed areas.
  • Our state parks are home to a variety of wildlife. Help us keep these animals wild by viewing them from a safe distance. Never feed or touch wildlife. Do not approach or attempt to move sick or injured wildlife. Please report any encounters with aggressive, sick or injured animals to a park ranger.
  • Snakes – always know where you are stepping.  If you have to traverse a log that has fallen across the trail, first step up onto the log then step down once you know the coast is clear, rather than just stepping over the log. Be cautious when climbing rocks or picking up firewood.  If you see a snake, maintain a distance of 6 feet. Most bites occur when people get too close or try to touch them.  Some gear you could consider using are
  • Tick populations are expected to rise this season. Take the following precautions to avoid them:
    • Walk in the middle of trails
    • Use insect repellent
    • Tuck your pants into your socks
    • After taking off gear always check for hitch-hiking ticks
    • Always do a “tick-check” with the help of a friend

Backpacking Safety

  • Be prepared – backpacking requires careful planning before heading into the wilderness.
  • Speak to a Ranger or Park Staff at the visitor center for current trail conditions, weather forecast, and reliability of water sources.
  • Drink and carry plenty of water (a minimum of 1 quart every 2 hours)
  • Let someone back at camp or at home know where you are going and when you plan on returning.
  • Do not walk off-trail or enter closed areas.
  • Wildlife lives in all of our state parks, even near urban areas.
  • Hike with a friend or family member.

Off-Highway Vehicle Safety

  • Always wear a helmet and goggles when riding off-highway vehicles.
  • Never ride under the influence of alcohol or drugs.
  • Ride only on designated trails and at a safe speed.
  • Supervise riders younger than 16; dirt bikes are not toys.
  • Never permit youngsters to ride dirt bikes that are too tall or too powerful for their capabilities.

Boating Safety

  • Wear a lifejacket for any aquatic activity such as boating.
  • Avoid alcohol when driving or riding on a boat.
  • Don’t swim near or under the back deck or swim platform while the boat motor is running. You can inhale Carbon Monoxide.
  • Keep your trash on board. Never throw cigarette butts, fishing line, or any other garbage into the ocean.
  • Use a phosphate-free soap to minimize the impacts of greywater on the marine environment. Also minimize discharge by doing dishes and showers on shore whenever possible.

Sun Safety

  • Always wear sunscreen to protect from the sun (even on overcast days.)
  • Seek the shade, especially during the sun's peak hours (10:00am-4:00pm).
  • Cover up with clothing, especially a broad-brimmed hat and UV-blocking sunglasses.  Use long sleeve rash guards with a high SPF rating if you are on the beach or in the water.
  • Get vitamin D safely through a healthy diet that includes vitamin supplements.
  • Examine your skin from head to toe once every month.
