Warmer Weather Will Speed Snowmelt, Increase River Flows; When Shelter-at-Home Restrictions Ease, Outdoor Recreationists Should be Wary of Cold-Water Hazards

PG&E Reminds Customers that Public Safety Risks Remain Despite Drier Year

SAN FRANCISCO--(BUSINESS WIRE)-- With temperatures forecast to increase this week, California’s snowpack will be melting faster, potentially filling rivers and streams with dangerously cold and swift moving water.

As some counties begin to ease shelter-at-home restrictions, Pacific Gas and Electric Company (PG&E) notes that California’s stay-at-home order remains in effect, and it’s important to continue practicing physical distancing. Californians may walk, run, hike and/or bike in their local neighborhoods as long as they continue to practice physical distancing of six feet.

For those who choose to venture near or in water, PG&E encourages them to take extra precautions when in or near rivers, especially around hydroelectric facilities and dams, where water flows can change rapidly. Anglers also are encouraged to take precautions as trout season has opened for most California rivers.

Although California’s snowfall is below normal, runoff is expected to continue into early summer.

“Public safety is our highest priority. We encourage everyone recreating in or near water to plan at all times how they can quickly and safely escape in case of changing water flows and cold temperatures,” said Jan Nimick, PG&E vice president of Power Generation.

Most California rivers are fed by snowmelt, making them cold even in summer. Simple actions such as recognizing if the water is too cold or swift, knowing your limits, wearing a life jacket and simply not entering the water when conditions are deemed unsafe can save a life.

Below are some water safety tips:

Stay Out and Stay Alive - Stay Out of Canals and Flumes

  • Recreating in PG&E canals and flumes is strictly prohibited. Stay off elevated flumes and out of these water conveyances, regardless of who owns them, as they are very dangerous due to slippery sides and fast-moving cold water. Be mindful of signs and warnings. Stay out of areas that are signed as restricted, fenced off or buoy-lined.

Know the Risks

  • Prevention is the best way to save a person from drowning. By the time a person is struggling in the water, a rescue is extremely unlikely and places the rescuer at risk.
  • Sudden immersion in cold water can stimulate the “gasp reflex,” causing an involuntary inhalation of air or water. It can even trigger cardiac arrest, temporary paralysis, hypothermia and drowning. When faced with swift water, even the strongest swimmers can be easily overwhelmed.
  • Cold water entering the ear canal can cause vertigo and disorientation. This can confuse swimmers, potentially causing them to venture deeper into the water.
  • Cold water also reduces body heat 25 to 30 times faster than air does at the same temperature and causes impairment that can be fatal.

Learn About Self-Rescue Techniques

  • If you do fall into the water, here are some survival tips:
    • Don’t panic. Try to control your breathing; don’t gasp. A sudden, unexpected fall into cold water causes an involuntary gasp (or torso) reflex. It takes less than one-half cup of water in a person’s lungs to drown. If you remain calm, you have a greater chance of self-rescue.
    • If you have a boat, stay with it. It will help you stay afloat and will be seen more easily by rescuers. If it’s capsized and a portion of the craft is above water, try to climb on top.
    • Stay afloat with the help of a life jacket, regain control of your breathing and keep your head above water in view of rescuers.
    • If possible, remove heavy shoes. Look for ways to increase buoyancy such as by holding onto seat cushions or an ice chest.
    • If you’re in the water with others, huddle together facing each other to help everyone stay afloat and keep warm.
    • If you do fall into a river without a life jacket, keep your feet pointed downstream and turn onto your back.
    • If you fall into the water with waders on, roll onto the shore. Wear a belt with waders.

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 during spring and early summer snowmelt. Rising water can make these obstacles even more treacherous. Guided trips for inexperienced paddlers are recommended.

Wear a Coast Guard-approved Life Jacket

  • Conditions change quickly in open water and even the best swimmers can misjudge the water and their skills when boating or swimming.

Adult 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. Use the buddy system and never swim alone.
