The heavy snows of winter and spring have left way above normal levels of snow in the mountains of the Shasta-Trinity National Forest, Klamath National Forest, and other forests and national parks of northern California.
And when that snow melts, there is dangers for hikers crossing streams on the trails, or swimming in lakes. Fishermen and kayakers and other boaters need to also pay attention.
Here’s some advice about snowmelt dangers from the Shasta-Trinity National Forest:
As warm weather sets in and the snowpack begins to melt in the surrounding mountains, the Shasta-Trinity National Forest staff urges outdoor recreationists to take precautions when playing in or crossing streams and rivers. This year’s snowpack is 40 percent greater than average which means increased flow and very cold water.
“Crossing streams can be fun and is adventurous, but you need to be extremely careful and prepared for changing conditions” Christine Mai, forest hydrologist, said. A trickle in the morning can turn into a roaring stream in the afternoon because snow melt increases throughout the day as temperatures rise. “Be prepared to spend the night or ensure there is an alternate route in case you can’t cross back the way you came.”
“Always avoid crossing frozen lakes or streams which may still be present at higher elevations,” Mai added. “What appears stable at the surface can be treacherous below and you do not want to break through into ice-cold water.” Remember that sudden immersion in ice-cold water can stimulate a gasp reflex causing an involuntary inhalation of air or water. It can even trigger cardiac arrest, temporary paralysis, hypothermia and drowning.
“And be sure to wear appropriate clothing,” Mai said. Lighter, moisture-wicking fabrics are preferred. Avoid wearing jeans. Wet jeans can act like an anchor weighing you down in swift waters. Maintain or bring extra dry foot wear. A safety pack with a flashlight, dry or waterproof matches, a light jacket and an extra snack are smart accessories for a day hike that could become an extended stay.
Swimmers, paddlers, boaters, anglers and even hikers cooling off at the water’s edge can be surprised by a sudden change in water flow. Stay safe by wearing a life jacket near deep water, avoiding alcohol, looking for submerged hazards, being aware of the current and checking local conditions before your trip. Parents should also exercise caution with young children playing in or near the water.
“We expect a lot of forest visitors as the weather improves. Hiking and camping and just getting outdoors is great fun for the whole family,” Mai said. “We just want to remind everyone to take a little extra care around the rivers and streams as they enjoy themselves on the Shasta-Trinity National Forest.”
Be very careful out there. I’ve nearly been swept away a couple times in my life, particularly in Canyon Creek in the Trinity Alps.
