This document presents the results of surface-water-quality data retrievals for Fossil Butte National Monument from six U.S. EPA national databases (STORET, RF3, IFD, DRINKS, GAGES, DAMS). It provides a complete inventory of retrieved water quality parameter data and stations, descriptive statistics and graphical plots characterizing period of record, annual and seasonal tendencies and trends, comparisons to EPA and WRD screening criteria, and an Inventory Data Evaluation and Analysis (IDEA) to determine which Level I water quality parameters have been measured. The report includes disks containing digital copies of all data and report components.
