COPPER CENTER, AK – In the morning of July 25th, local observers noted that the level of Hidden Creek Lake has begun to fall. This is consistent with conditions that often precede the release of water into the Kennicott River. Residents and visitors in the area should use caution if or when high water results. These conditions can be dangerous for anyone that may be on the Kennicott River or downstream rivers and streams, such as the Chitina and Copper Rivers.
 
The high-water event is an annual Hidden Creek Lake outburst flood, called a jökulhlaup (an Icelandic word pronounced yo-KOOL-lahp). The Hidden Creek Lake is created as water builds up in the area where it meets the Kennicott Glacier. For the outburst flood to occur, the lake must breach its dam and drain catastrophically when it either causes its ice dam to float or causes large meltwater channels beneath the glacier ice to burst and drain rapidly. This type of event causes flooding at the Kennicott River, and other downstream waterways.
 
The rivers of Wrangell-St. Elias offer a remote, backcountry experience, but require extreme caution due to the cold, glacially fed waters. Hypothermia is a danger even after a brief submersion, regardless of air temperature. Always wear a drysuit and a personal floatation device (PFD). High water from the jökulhlaup, and an increase in water levels from recent warm temperatures may also create hazards for backcountry travelers. Knowing how to cross rivers safely is essential for wilderness travel. Remember to choose the safest time to cross, choose the safest place and method to cross, protect your feet, prepare to get wet, and be prepared to respond in the case of an emergency. Please use caution and care when boating or recreating on or near the Kennicott, Chitina, or Copper Rivers, as well as other streams and rivers in Wrangell-St. Elias National Park & Preserve.
