Host Dano sits down with Don Habeger (Exec Dir, First Things First), Frank Bergstrom (President, FTF), and Meadow Lane residents Cindy & Mike Dow to unpack this year’s Suicide Basin jökulhlaup: what they lived, what the data shows, why HESCO barriers aren’t enough, and the community push for a permanent, engineered fix.

Key Takeaways

• Records keep falling. Reported Mendenhall Lake crests:
  • 2023: 14.9 ft (~25,200 cfs, per episode)
  • 2024: 15.99 ft (~4,700 cfs, per episode)
  • 2025: 16.67 ft (~50,000 cfs, est. per episode)
    (Guests’ figures as stated on-air; trend = bigger, faster outbursts.)
• What residents saw this year
  • New percolation in Meadow Lane/Alder Circle; water pulsing up/receding through gravel.
  • Log “harpoons.” Full-length trees with root balls riding the current, spearing riprap/fences; would punch through a house.
• Limits of HESCOs
  • They raise river head, which also drives seepage through sandy/gravel soils.
  • Vulnerable to log impacts and bank erosion; require constant, costly maintenance (~$1M in repairs this year, per city meeting cited).
  • Short-term mitigation, not a long-term solution.
• Infrastructure hit
  • 3 of 4 river crossings were closed at one point (Back Loop, Pedestrian, Montana Creek bridges noted); fiber cut impacted regional comms; Back Loop has since reopened.
• Human toll
  • Residents describe post-traumatic stress, feeling unsafe, and some preparing to leave Juneau.
• What First Things First is advocating
  • Engineered levee/dam at the Mendenhall Lake outlet to attenuate peak flows—store more during the outburst, then release in a controlled way.
  • Expedite geotech now; goal is a 12-month timeline, not “study forever.”
  • Federal leadership is engaged (delegation + USACE site visits); Governor pre-declared the 2025 flood a disaster, enabling rapid DOT bridge work.
  • Guests still don’t feel urgency from CBJ; want proactive planning and communication.

Notable Quotes

• “This is the most predictable flood perhaps on earth.”
• “HESCOs are a short-term fix…they increase head in the river and drive seepage into yards.”
• “We need a long-term solution now, not in the ‘long term.’”
• “I’d stay if I knew a levee was coming.”
