Final 2012 Integrated Report: 
A characterization of the data, including its intended use and limitations.
Sections 305(b) and 314 of the Clean Water Act (CWA) require states, territories, and authorized tribes to provide biennial reports to EPA on the condition of waters within their boundaries. EPA regulations at 40 CFR 130.7 require states to provide biennial submissions of impaired waters lists. EPA provides guidance on these reports in a way that supports the Agency's strategy for achieving a broad-scale, national inventory of water quality conditions. The guidance is from EPA to states, territories, authorized tribes, and interstate commissions ("jurisdictions") to help states prepare and submit Section 305(b) reports to EPA. Use of the integrated report (IR) format provides jurisdictions a recommended reporting format and suggested content to be used in developing a single document that integrates the reporting requirements of Sections 303(d), 305(b), and 314. This format allows jurisdictions to report on the water quality standards attained for all waters, document the availability of data and information for each segment, identify certain trends in water quality conditions, and set priorities for protecting and restoring the health of the nation's aquatic resources. Section 305(b) of the Clean Water Act requires each state to conduct water quality surveys to determine a water body's overall health, including whether or not basic uses are being met. States, tribes, and other jurisdictions define appropriate uses for a waterbody and incorporate these uses into water quality standards that are approved by EPA. Water body uses include aquatic life protection, fish and shellfish production, drinking water supply, swimming, boating, fishing, and agricultural irrigation, among others.
The Idaho Integrated Water Quality Monitoring and Assessment Report is the reporting method used by the U.S. EPA which combines the 303(d) impaired streams/lakes and the 305(b) overall assessment of Idaho's waters for the 2012 Federal Reporting Cycle.

The Clean Water Act protects and preserves water quality in the United States by protecting the uses designated for specific waterbodies. The results of the 305(b) assessments are not raw data but rather statements of the degree to which each water body supports the uses designated in state or tribal water quality standards. For example, two rivers may have the exact same chemical and physical makeup, but one of the rivers may be considered as impaired because of different water quality standards

A reach is a continuous piece of surface water with similar hydrologic characteristics. Some unconnected (isolated) features are also reaches, for example, isolated lakes and single, unconnected streams. In the NHD, each reach is assigned a reach code. A reach may be composed of a single feature, like a lake or isolated stream, but reaches may also be composed of a number of contiguous features due to the preservation of reach codes that came when the 24K NHD was created from the 100K NHD. A reach code is a 14 digit code comprised of two parts. The first eight digits are the HUC for the subbasin in which the reach exists, and the last six digits are a sequential number that is assigned when reach codes are allocated in the subbasin. Each reach code occurs only once throughout the nation, but a reach code may be on a number of contiguous features, if they all belong to the same reach. Once assigned, a reach code is permanently associated with its reach. If the reach is deleted, its reach code is retired.K

Strahler Stream Order
Attribute definition source:
When using stream order to classify a stream, the sizes range from a first order stream all the way to the largest, a 12th order stream. A first order stream is the smallest of the world's streams and consists of small tributaries. These are the streams that flow into and "feed" larger streams but do not normally have any water flowing into them. In addition, first and second order streams generally form on steep slopes and flow quickly until they slow down and meet the next order waterway.

ATTR_VAL - Waterbody ID -- Water Body Identification System (WBID) - The Idaho WBID is a geo-referenced network of Idaho water bodies based on a combination of two hydrography scales: 1:100,000 and 1:250,000. The numbering or coding system of the WBID is based on the USGS cataloging units in Idaho. Refer to Section 2.2 in the Water Body Assessment Guidance Document for additional information ( . The WBID is the bases of identifying water bodies in the water quality standards and implementing the watershed management approach in Idaho. The system is also the basic unit of record for water quality assessment information.

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.
