How and Why Upper Colorado River Basin Land, Water, and Fire Managers Choose to Use Drought Tools (or Not)

Preparing for and responding to drought requires integrating scientific information into complex decision making processes. In recognition of this challenge, regional drought early warning systems (DEWS) and related drought-information tools have been developed under the National Integrated Drought Information System (NIDIS). Despite the existence of many tools and information sources, however...
