Supplemental information:
The Water Body Assessment Guidance (WBAG) describes DEQ's methods for evaluating data and determining beneficial use support of Idaho water bodies. Assessing a water body involves analyzing and integrating multiple types of data to determine the degree of beneficial use support and biological integrity of the water body and compile descriptive information about the water body. The current WBAG, published in 2002, is referred to as “WBAG II,” as it replaced the original WBAG published in 1996.

DEQ recognizes three categories of beneficial use support status: fully supporting, not fully supporting, and not assessed. “Fully supporting” means that a water body is in compliance with water quality standards and criteria and supports all designated and existing beneficial uses. “Not fully supporting” refers to a water body that is not in compliance with all water quality standards or criteria or is not supporting all beneficial uses. The “not assessed” category describes water bodies that have either not been monitored by DEQ at all or have been monitored to some extent, but are missing critical information needed to complete an assessment.

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standards for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
Time convention: local time
Metadata profiles defining additonal information:
Profile: ESRI Metadata Profile
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.0
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
