U.S. Environmental Protection Agency, states, and tribes are conducting a series of surveys of the nation's aquatic resources. Often referred to as probability-based surveys, these studies provide nationally consistent and scientifically-defensible assessments of our nation’s waters and can be used to track changes in condition over time. Each survey uses standardized field and lab methods and is designed to yield unbiased estimates of the condition of the whole water resource being studied.
The Drought Risk Atlas is an online visualization tool that allows users to analyze and compare historical and contemporary droughts at the local level to better understand drought risk. The atlas allows users to explore past drought characteristics for specific geographic regions by compiling data from numerous monitoring stations; users can select a monitoring station within their area, as well as select other stations that exhibit similar precipitation patterns.
The Drought Management Database collects and provides examples of how different U.S. regions and sectors are responding to and mitigating drought. This online database can be useful for various levels of government looking to engage in drought preparedness and response planning, as well as for sectoral decision makers looking to undertake similar planning efforts, as it provides real-world examples and lessons learned.
The Drought Impact Reporter is an online database that maps recorded drought impacts in the United States. The Drought Impact Reporter defines a drought impact as “an observable loss or change that occurred at a specific place or time because of drought.” The reporter maps the number of drought-related impacts down to the county level, and provides critical information detailing type, location, and extent of drought impact, along with relevant source information.
