This presentation will demonstrate the Data Review and Outlier Detection tool of the Water Use Toolkit. State agency reported water-use data often contain erroneous data and outliers, and current USGS water use databases do not have graphical user interfaces for easily reviewing these data. The Data Review and Outlier Detection tool of the Water Use Toolkit allows USGS staff to interactively review time series plots of annual and monthly water-use data, and provides the users a .csv file of potential outliers and data anomalies. The Water Use Toolkit is a new USGS multiple component tool that was designed to improve efficiency in entering site-specific water-use data, avoid duplication of sites, and provide graphical interfaces for reviewing water quantity data in USGS databases.
