SECURE Water Act Report to Congress

2021 SECURE Water Act Report CoverSECURE Water Act Section 9503(c) — Reclamation Climate Change and Water 2021

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.
