A two and a half day workshop on water and ice was convened as part of a Canada/United States (US) bilateral meeting to determine where Canada and the US can collaborate to advance the water and ice-related goals of the Group on Earth Observations (GEO) within the frameworks of their national GEO efforts. The workshop was held October 28-30 at the National Science Foundation in Arlington, Virginia, USA.

The workshop included presentations and discussions aimed at:

1. Identifying observational and analysis activities where the US and Canada can collaborate within the GEO framework to accelerate progress towards common goals.
2. Developing a plan for how Canada and the USA will work together to achieve significant advances in the areas of water and ice monitoring, modeling, and societal benefit assessment.
3. Clarifying how the US and Canada can jointly approach international GEO activities to ensure that the capabilities, interests and concerns of both countries are effectively addressed.

USGEO-CGEO Bilateral Meeting: After the workshop, the USGEO and CGEO leadership met to review outcomes and recommendations from the workshop and consider future bi-lateral cooperation. The leadership also discussed US-Canada collaboration in the broader context of GEO, including regional cooperation through GEOSS in the Americas and preparation for the upcoming GEO-V Plenary in Bucharest, Romania.
