What does this data set describe?

Title:
Assessed Waters (Surface Water Quality Assessment & Monitoring) Image Service for Idaho

Abstract: 
Every two years, DEQ is required by the federal Clean Water Act to conduct a comprehensive analysis of state water bodies to determine whether they meet state water quality standards or if additional pollution controls are needed to meet beneficial uses.

Public input into the evaluation process is important. In March 2002, DEQ issued a call for scientific data on surface water quality in Idaho's streams, rivers, lakes and reservoirs. Following review and analysis of data submitted by the scientific community and compiled by DEQ, a draft report on the status of surface water in water bodies statewide was developed.

Supplemental information: 
92,948 miles of water exist in Idaho, according to DEQ’s accounting system. 
More than half the state’s water has been monitored and assessed. 
Twice as many streams have been monitored and assessed this cycle than during the 1998 listing cycle. 
15,000 miles of streams monitored and assessed this cycle were found to meet water quality standards. 
The proportion of streams meeting their beneficial uses is increasing. 
The number of miles of water quality limited or impaired streams is largely unchanged from 1998—a total of 21,000 miles compared to 20, 900 in 1998, according to DEQ’s accounting system. 
20% of all waters in the state are deemed to meet water quality standards and their beneficial uses. 
13,000 miles of TMDLs submitted to EPA have been approved. 
2,417 miles of previously listed waters were found to meet their beneficial uses and do not need a TMDL. 
4,609 miles of streams were removed from those needing TMDLs because they were listed for flow and/or habitat alternation. Flow and habitat are not considered pollutants under the Clean Water Act and do not require a TMDL. 
207 assessment units were added for temperature this cycle. However, many of these may be due to natural background. Further study may find some of these are not water quality limited.

      False easting: 2500000.000000
      False northing: 1200000.000000

      Planar coordinates are encoded using coordinate pair.
      Abscissae (x-coordinates) are specified to the nearest 0.002048.
      Ordinates (y-coordinates) are specified to the nearest 0.002048.
      Planar coordinates are specified in meters.

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.
      The flattening of the ellipsoid used is 1/298.257222.

Why was the data set created?

Assessed water bodies are designated in the draft "2002-03 Integrated 303(d)/305(b) Report" as either supporting or not supporting water quality standards and beneficial uses. Water bodies that do not meet water quality standards are called "water quality limited" or "impaired," and require development of water quality management plans known as Total Maximum Daily Loads (TMDLs) to bring them back into compliance and protect their beneficial uses. Water bodies previously designated impaired that now meet water quality standards are removed from the water quality limited list.
