A new report on statewide hydrology is now available, based on a study by The Wilderness Society in conjunction with SNAP. To download the report, look under Reports in the menu on the left.

Increases in temperature and changes in precipitation have had profound effects on regional hydrology, including shrinking wetlands, glacier and polar sea ice recession, permafrost melting, and an increase in fire frequency and intensity across the landscape as a result of increased drought and thunderstorms. Continuation of these trends will likely lead to further changes in the hydrologic cycle, with significant implications for the people, places, and wildlife that depend on Alaska’s water resources. In an effort to better understand where and when changes in hydrology are likely to occur, we developed a tool for mapping future water availability across
the state.
