  • Welcome

    The Alaska Water Level Watch (AWLW) is a collaborative group working to improve the quality, coverage, and accessibility to water level observations in Alaska’s coastal zone.

    Water level data has many applications that contribute to safe navigation, storm modeling and mapping, tsunami warnings, watches, and advisories, incident response, search and. rescue operations, tidal datums, sea level trends, storm trends, and much more.

  • Water Level Build-Out Plan

    Identify existing sensor assets, remaining gaps, and updated priorities in this web map. Also access other information and tools about water levels like the most up-to-date projections of relative sea level rise.

  • Access & Contribute Data

    Alaska Water Level Watch is a forum for crowd-sourced water level data. Data are contributed and accessed through the AWLW data portal.

    Contributing data is easy! Use our station log template and instruction forms to provide metadata with your water level data.
