West-wide Climate Risk Assessments


The WWCRAs focus on the development of consistent baseline information of the risks and impacts associated with climate change as they relate to the mission of the Bureau of Reclamation.  In order to identify the risks and impacts, the WWCRAs focus on utilizing the best available science within a series of implementation activities that will continually update our understanding of how climate change affects risks to supply and demand and impacts operations as identified in the conceptual diagram (Figure 2).

Figure 2 identifies the analytical steps to utilize climate information within a planning context which requires:

(A) Transforming General Circulation Model information into a spatial and temporal scale relevant to a planning context.

(B) and (C) utilizing the spatially and temporally relevant climate information to identify projections of water supply and demand.

(D) Simulating future operations of Reclamation activities as informed by the water supplies and demands developed in (B) and (C).

(E) Determining Aquatic Ecosystem Responses

The results of implementation activities (A) – (D) can then be utilized, at a baseline level, to identify the impacts on water delivery, hydroelectric power generation, recreation, fish and wildlife habitat, endangered, threatened, or candidate species under the Endangered Species Act, water quality issues, ecological resiliency, and flood control management.
