🌊 The Stillaguamish River may look inviting, but cold water is a serious risk—even on hot days.
Water temperatures remain low year-round and can cause cold shock or hypothermia in minutes. This can impact breathing, strength, and your ability to stay afloat.
✅ Always wear a properly fitted life jacket
✅ Limit time in the water
✅ Go with a partner—never alone
Cold water can overwhelm even strong swimmers. Plan ahead so your day stays safe.
