  • Capturing a Storied Past: Historical Photo Analysis Guides Restoration Work at World War II Site in Alaska

    The U.S. Army Corps of Engineers Alaska District, in collaboration with the USACE Army Geospatial Center, is using historical photographic analysis to help determine the locations of structures, features and abandoned military munitions on Amaknak and Unalaska Islands.
  • Innovation leads to productive season for safety upgrade at Moose Creek Dam

    With the onset of winter, the U.S. Army Corps of Engineers – Alaska District capped off a successful summer by doubling its progress from last year to build a cement barrier wall in the center of the dam. The safety improvement project is now about halfway complete as the team works to reinforce 4.7 miles of the 8-mile-long earthen structure.

  • Summary of Ice Jams and Mitigation Techniques in Alaska

    Abstract: Ice is an important part of the Alaska ecosystems and can form through dynamic (e.g., frazil) or static (e.g., thermal) processes. In Alaska, both freeze-up and breakup ice jams occur, however breakup jams during the spring snowmelt period are most common. Historically there have been many river systems in Alaska that have chronic ice jam issues. These ice jams have resulted in several significant ice jam floods. There are several ice jam mitigation techniques that can be used to either provide state and local emergency managers warnings of a potential ice jam or reduce the impacts of a jam. Common relatively low-cost mitigation methods that can be implemented prior to a jam forming are monitoring and detection of movement, mechanical or thermal weakening of the ice cover. Permanent measures are also effective and maybe the best option in specific locations. These measures include structures to keep flood waters from inundating areas (e.g., levee) or they can be designed to hold back ice fragments moving downstream (e.g., ice boom and pier structures). Climate change impacts to ice processes are important for Alaska and additional investigations will be needed to quantify the ecologic, hydrologic, and societal impacts.
