The State of Global Water Resources Report, published annually by WMO, provides a comprehensive quantitative overview of global water resources, with a focus on hydrological variability and trends. It supports countries, decision makers and stakeholders in understanding the current state of water resources, identifying hotspots and supporting effective water management strategies. The report is based on data contributed by WMO Members, as well as information from global hydrological cycle.

• Lake levels were consistently below to much below normal across the Mackenzie, Fraser and Churchill river catchments in Canada’s Northwest Territories.

• In the Middle East and Central Asia, lake levels were much below normal.
• In Northern Europe and the European part of the Russian Federation (Lake Ladoga), lake levels were above normal. Lake Baikal also recorded above-normal levels.
