News Release: Reclamation releases Climate Change Adaptation Strategy (April 20, 2023)

2021 SECURE Water Act Report to Congress

SECURE Water Act Report CoverThe Bureau of Reclamation released final technical reports supporting the Water Reliability in the West - 2021 SECURE Water Act Report. Reclamation's 2021 West-Wide Climate and Hydrology Assessment and seven individual basin reports provide detailed information on climate change impacts and adaptation strategies to increase water supply reliability in the West. A new 2021 SECURE Report Web Portal is also available to provide a user-friendly, web-based format for delivery of information in the reports.

The 2021 West-Wide Assessment provides estimates of changes in temperature, precipitation, snowpack, and streamflow across the West using consistent methodology, similar to previous SECURE Water Act Reports. For this report, additional drought analyses based on paleohydrology (using tree rings) was performed. These results will enable water managers to compare the frequency and severity of droughts that occurred several hundred years ago to projections of future droughts and develop water management strategies in time to take action.
