COPPER CENTER, Alaska – On July 18, local observers noted that the level of Hidden Creek Lake had begun to fall. On July 19, rangers observed new, significant releases of water next to the Kennicott Glacier and into the Kennicott River. Residents and visitors should use caution as the river rises and can get updates about its level from the US Geological Survey. These conditions can be dangerous for anyone on the Kennicott River as well as downstream in areas such as the Chitina and Copper Rivers.

Background

The annual Hidden Creek Lake glacial outburst flood, called a jökulhlaup (an Icelandic word pronounced yo-KOOL-lahp) contributes to this rise in river levels. In the spring and early-summer, Hidden Creek Lake rises as water builds up in the area where Hidden Creek meets the Kennicott Glacier. The outburst flood happens unpredictably when the ice holding back Hidden Creek Lake changes or melts, giving water from the lake routes to drain under and/or through the Kennicott Glacier.

High water from the jökulhlaup coupled with water from recent rain may increase hazards for backcountry travelers or boaters. Crossing rivers responsibly is important. Before you cross water, consider:

• Times of day when flow is relatively low such as early in the morning.
• Appropriate locations and methods to cross the river.
• Protection for your feet.
• Preparing to get wet (and dry off).
• How you might assist others (or self-rescue) if the crossing does not go as planned.

The rivers of Wrangell-St. Elias offer remote, backcountry experiences. 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 and Preserve. Hypothermia is a danger after even a brief submersion, regardless of air temperature. Consider using a drysuit and a personal floatation device (PFD) if you recreate at or on water in the park.
