Abstract:
Washington State's 2012 Water Quality Assessment (WQA) is produced in the Environmental Protection Agency's "Integrated Report" format. The WQA consists of both the 303(d) List and the 305(b) Report. The 303(d) List is comprised of only Category 5 listings. The 305(b) Report lists all waters and all categories. The 2012 WQA is presented on the 1:24k LLID (Longitude/Latitude ID) hydro layer.
Purpose:
Creation of the 303(d) List and 305(b) Report satisfies the state's requirement under the Clean Water Act to report impaired water to the EPA. This Water Quality Assessment was approved by EPA on December 21, 2012.
Supplemental_Information:
The 2012 WQA rates sampled waters into one of five categories. This GIS layer represents the 305(b) List of Categories 1 through 5.
Category 1: Meets tested standards. Placement in this category means that the waterbody segment meets the criteria it was tested for. It does not necessarily mean that a water body is free of all pollutants. Most water quality monitoring is designed to detect a specific array of pollutants, so placement in this category means that the water body met standards for all the pollutants for which it was tested. Specific information about the monitoring results may be found in the individual listings.
Category 2: Waters of concern. This category lists waterbody segments where there is some evidence of a water quality problem, but not enough to require production of a TMDL. There are several reasons why a water body would be placed in this category. A water body might have pollution levels that are not quite high enough to violate the water quality standards, or there may not have been enough violations to categorize it as impaired according to Ecology's listing policy. There might be data showing water quality violations, but the data were not collected using proper scientific methods. In all of these situations, these are waters that we will want to continue to test.
Category 3: Insufficient or No data. This category houses those listings where the assessed data was insufficient to determine a proper categorization of the water. Water bodies that have not been tested will not be individually listed, but if they do not appear in one of the other categories, they are assumed to belong in Category 3.
Category 4: Polluted waters that do not require a TMDL. This category is for waterbody segments that have pollution problems that are being solved in one of three ways. * Category 4a is for waterbody segments that have an approved TMDL in place and are actively being implemented.
* Category 4b is for waterbody segments that have a pollution control plan in place that is expected to solve the pollution problems. While pollution control plans are not TMDLs, they must have many of the same features and there must be some legal or financial guarantee that they will be implemented.
* Category 4c is for waterbody segments impaired by causes that cannot be addressed through a TMDL (not due to a pollutant). These impairments include low water flow, stream channelization, and dams. These problems require complex solutions to help restore streams to more natural conditions.
Category 5: Polluted waters that require a TMDL. Category 5 represents the 303(d) list, the traditional list of impaired water bodies. Placement in this category means that Ecology has data showing that the water quality standards have been violated for one or more pollutants, and there is no TMDL or pollution control plan. TMDLs are required for the water bodies in this category.

The base hydro layer is the 1:24k LLID from the Pacific Northwest Hydro Framework consortium.
Process_Step:
Process_Description:
1) Join Watershed Assessment Tracking System (WATS) tabular listing data to 24K Hydrography polygon layers on LLID number -water body, water grid and water quarter grid (sediments only).
2) Extract joined polygons (those with associated listings) to a separate polygon feature class.
3) Join WATS tabular listing data to 24K Hydrography water courses on LLID number and use lower and upper segment route address values to create linear events depicting the listed segments.
4) Extract the events of the listed segments to a line feature class.
5) Buffer the line feature class by 50 feet with the Full and Flat options to create a polygon layer of listed stream segments.
6) Merge the listed stream segment polygons with the listed polygons created in step 2 to create a single polygon layer of listed water bodies.
7) Use a Python script to create duplicate geometries for polygons with multiple listings so that there is a one-to-one relationship between polygon features and rows in the listing database.
8) Export the polygons to a shapefile for publication as a download on the agency website.

Attribute_Definition_Source: Pacific Northwest Hydrography Framework
Attribute:
Attribute_Label: UPPER_ROUTE_ADDRESS
Attribute_Definition:
Upper Route Measure - Distance from mouth of stream in kilometers. Defines the upstream extent of a listing where a stream exits a specific section, based on township, ranges, and sections.
Attribute_Definition_Source: Pacific Northwest Hydrography Framework
Attribute:
Attribute_Label: WATERGRID_CELL_NR
Attribute_Definition:
Grid Cell Identification number. Used for all marine waters and the large freshwater bodies which are over 1500 acres in size.
Attribute_Definition_Source: Washington State Department of Ecology
Attribute_Domain_Values:
Unrepresentable_Domain:
The grid cell number is a concatenation of the latitude and longitude (in decimal degrees) of the cell centroid. The grid cell numbers for sediment listings have a quadrant identifier appended (NE, NW, SE, or SW).
Attribute:
Attribute_Label: WATERBODY_NAME
Attribute_Definition:
Waterbody Name - geographic names in use by the Water Quality Program for the Assessment (these names do not always match the official names from the GNIS).
Attribute_Definition_Source: Water Quality Program, Washington State Department of Ecology
Attribute_Domain_Values:
Unrepresentable_Domain: Character string representing the water body name.
Attribute:
Attribute_Label: CATEGORY
Attribute_Definition: Category Description - Water/Sediment Category rating
Attribute_Definition_Source: Washington State Department of Ecology
Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: 1
Enumerated_Domain_Value_Definition:
Category 1: Meets tested standards. Placement in this category means that the waterbody segment meets the criteria it was tested for. It does not necessarily mean that a water body is free of all pollutants. Most water quality monitoring is designed to detect a specific array of pollutants, so placement in this category means that the water body met standards for all the pollutants for which it was tested. Specific information about the monitoring results may be found in the individual listings.
Enumerated_Domain_Value_Definition_Source: Washington State Department of Ecology
Enumerated_Domain:
Enumerated_Domain_Value: 2
Enumerated_Domain_Value_Definition:
Category 2: Waters of concern. This category lists waterbody segments where there is some evidence of a water quality problem, but not enough to require production of a TMDL. There are several reasons why a water body would be placed in this category. A water body might have pollution levels that are not quite high enough to violate the water quality standards, or there may not have been enough violations to categorize it as impaired according to Ecology's listing policy. There might be data showing water quality violations, but the data were not collected using proper scientific methods. In all of these situations, these are waters that we will want to continue to test.
Enumerated_Domain_Value_Definition_Source: Washington State Department of Ecology
Enumerated_Domain:
Enumerated_Domain_Value: 3
Enumerated_Domain_Value_Definition:
Category 3: Insufficient or No data. This category houses those listings where the assessed data was insufficient to determine a proper categorization of the water. Water bodies that have not been tested will not be individually listed, but if they do not appear in one of the other categories, they are assumed to belong in Category 3.
Enumerated_Domain_Value_Definition_Source: Washington State Department of Ecology
Enumerated_Domain:
Enumerated_Domain_Value: 4A
Enumerated_Domain_Value_Definition:
Category 4A is for waterbody segments that have an approved TMDL in place and are actively being implemented.
Enumerated_Domain_Value_Definition_Source: Washington State Department of Ecology
Enumerated_Domain:
Enumerated_Domain_Value: 4B
Enumerated_Domain_Value_Definition:
Category 4B is for waterbody segments that have a pollution control plan in place that is expected to solve the pollution problems. While pollution control plans are not TMDLs, they must have many of the same features and there must be some legal or financial guarantee that they will be implemented.
Enumerated_Domain_Value_Definition_Source: Washington State Department of Ecology
Enumerated_Domain:
Enumerated_Domain_Value: 4C
Enumerated_Domain_Value_Definition:
Category 4C is for waterbody segments impaired by causes that cannot be addressed through a TMDL (not due to a pollutant). These impairments include low water flow, stream channelization, and dams. These problems require complex solutions to help restore streams to more natural conditions.
Enumerated_Domain_Value_Definition_Source: Washington State Department of Ecology
Enumerated_Domain:
Enumerated_Domain_Value: 5
Enumerated_Domain_Value_Definition:
Category 5: Polluted waters that require a TMDL. Category 5 represents the 303(d) list, the traditional list of impaired water bodies. Placement in this category means that Ecology has data showing that the water quality standards have been violated for one or more pollutants, and there is no TMDL or pollution control plan. TMDLs are required for the water bodies in this category.
