A 2013 Colorado Water Conservation Board study found that adaptive capacity of water providers increased between drought events in 2002 and 2012, motivating this study to add nuance to those conclusions and investigate what kind of variation of adaptive capacity existed during this period and what factors contributed to the increase. From these findings, strengths and weakness of regional adaptation can be assessed to determine potential vulnerabilities to future drought conditions. To analyze how the capacity of water providers to cope with environmental changes translates to adaptive capacity, this study uses this framework to structure evaluation of how stress affects institutions and water providers, how adaptive capacities were changed, and implications this has for vulnerability to future climate changes. Specifically, it investigates: 1. How adaptive capacity of water providers manifested between two drought periods; 2. What mechanisms caused changes in adaptive capacity; and 3. How stress / exposure may change under future climate scenarios.Chapter 2 focuses on how water providers' ability to cope with drought changed between the 2002 and 2012 events. While other studies have sought to evaluate these stakeholders' vulnerabilities and adaptive capacities, they have focused on a subset of water providers who are often in large cities and engaged with state agencies, so the scope of differences in providers' abilities to manage severe water shortages and potential vulnerabilities to future changes is still unknown. This study introduces a methodology to assess adaptive strategies used by South Platte River Basin water providers to increase understanding of their adaptive capacity to cope with shocks and stress. Specifically, it evaluates how water providers altered their drought management strategies during and between two former drought periods and how shifts affected their abilities to cope with extreme events. From this a suite of response options and management patterns that increase adaptive capacity are isolated and potential vulnerabilities to stress are discussed. The research methodology uses an 'analog approach' to evaluate how water systems were impacted by two past drought events (in 2002 and again in 2012), alterations made to management strategies after the first drought, and how they performed during the subsequent drought. From this analysis, it was determined that all water providers were less severely impacted by the 2012 drought than they were in 2002. A hierarchical cluster analysis was performed on response strategies to look at groups of water providers to understand what adaptive strategies they adopted and why those decisions were made. This study augments existing knowledge of vulnerability of stakeholders and the region because it provides an understanding of successful adaptive strategies but also sheds light on types of water users and attributes of systems that could create vulnerabilities to worsening drought conditions or water stress.Qualitative analysis revealed that the impacts of the 2002 drought were varied among providers, ranging from those who completely ran out of water, to others who were minimally affected. The 2012 drought had minimal impacts on all providers, a finding that was confirmed by a quantitative comparison of impacts. Analysis of management ability showed that all providers' ability to meet their water demand requirements improved from 2002 to 2012, and performance was actually better during the subsequent drought than during the period just before, showing that the adaptive strategies used improved adaptive capacity. Results of specific response strategies, using an Event History Calendar, revealed a shift in the overall number of strategies used and their distributions between the two drought periods. While demand management strategies still made up the majority of management decisions, there was a large shift towards using policy-related strategies and a large decline in emergency-related strategies. To capture common management changes and begin to understand motivations behind adaptive decisions, water providers were divided into groups based on strategies they used to manage the droughts and how they altered their strategies.
