Description:
Abstract:
This polygon theme contains a spatial representation of the 303(d) list and should be used in conjunction with the actual 303(d) list. The 303(d) list attribute information included in the GIS attributes table is generalized and is described below.
Purpose:
This layer was developed in order to portray spatially some elements of the 303(d) list and to assist in the 303(d) list development process

Title:
Streams on Oregon's 1998 303(d) list of Water Quality Limited Water Bodies
Geospatial_Data_Presentation_Form: vector digital data
Online_Linkage: <http://www.deq.state.or.us>

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Data: In the stream layer, RRN and FEAT_NAME are pulled from the USGS river reach data set. Occasionally, where the feature name was blank in the source USGS layer, names were input manually. In the lakes and reservoirs layer, attributes beyond the system items were entered manually.
Logical_Consistency_Report: Unknown
Completeness_Report:
Spatial Data: Some features may be lacking very short arcs, e.g. around .03 miles in length, as a result of selection techniques and tolerances. Line work in some cases may have been generalized from the original source USGS river reach data set as a result of processing. If features are not portrayed in the source USGS data set, they will not be portrayed in these GIS layers even if they are on the 303(d) list. Please contact the USGS for current and complete river reach data layers. Known problems in the 303(d) GIS representations: Basin Stream Problem Willamette McDowell Creek upstream boundary unknown A-3 Drain not located Umpqua East Fork Creek not located Elk Valley Creek forks not positively located Rogue Galls Creek not located Dry Creek naming convention, not located Bee Creek not located Hobart Creek not located South Coast Little Rock Creek not located Deschutes Tenmile Creek not located Umatilla Westgate Canyon not located Klamath Sycan River marsh used as upstream boundary Calahan Creek missed during edits Fourmile Creek missed during edits Malheur Lake Deep Creek naming convention, not located Fish Creek upstream boundary unknown

303(d) data attached to the 1:100,000 streams layer created by streamnet

Process_Description:
Processing History: Line work representing streams and lines and points representing area features, lakes and reservoirs were reselected from USGS 1:100,000 river reach data files for Oregon based the 303(d) list to create new GIS layers to represent the 1994/96 303(d) list. Out of the USGS river reach data sets ONLY those features on the 303(d) list appear in these layers. The attribute scheme was revised for the stream layer for the 1998 representation. Changes (additions, removals, modifications) were made to the GIS layers as the edits were done to develop the 1998 303(d)

Overview_Description:
Entity_and_Attribute_Overview:
Stream layer (S303_98) attributes associated with arcs (bays and sloughs are represented by centerlines): RRN - USGS River Reach Number (a concatenation of USGS Hydrologic Unit Code, Segment Number, and River Mile Index), 17 character field (Please note: This attribute should be used with caution as a unique linking code. This layer may not reflect most current USGS reach files. Some reaches have been split to better represent 303(d) waterbody extents.) FEAT_NAME: the name of the waterbody feature, 60 character field TEMP98: temperature (1 = listed, 0 = not listed), 2 integer field HAB98: habitat modification (1 = listed, 0 = not listed), 2 integer field FLOW98: flow modification (1 = listed, 0 = not listed), 2 integer field AQGROW98: aquatic growth, chlorophyll-a, nuisance aquatic vegetation (1 = listed, 0 = not listed), 2 integer field NUT98: nutrients, phosphorus (1 = listed, 0 = not listed), 2 integer field BIOCRIT98: biological criteria (1 = listed, 0 = not listed), 2 integer field BAC98: fecal coliform, E coli (1 = listed, 0 = not listed), 2 integer field DO98: dissolved oxygen (1 = listed, 0 = not listed), 2 integer field SED98: sedimentation (1 = listed, 0 = not listed), 2 integer field TOX98: toxics (1 = listed, 0 = not listed), 2 integer field PH98: pH (1 = listed, 0 = not listed), 2 integer field TURB98: turbidity (1 = listed, 0 = not listed), 2 integer field TDG98: total dissolved gas (1 = listed, 0 = not listed), 2 integer field TRIBAL: stream on tribal lands (E = entirely on tribal lands, P = partially on tribal lands), 1 character field DISCLAIM (this phase appears with all segments) "Refer to the 303(d) list as document of record", 50 character field Lakes and Reservoirs layer (L303_98) attributes associated with polygons : HUC: USGS hydrologic unit code, 8 integer field NAME: the name of the feature, 32 character field WATER: differentiates land-water features to accommodate "islands" in lakes and reservoirs (a "Y" indicates water, an "N" indicates non-water), 1 character field CAUSE: parameters for which the feature is water quality limited. Generalized from the 303(d) list. For example, "temp" used for "Temperature - Summer", 100 character field Possible cause/parameter attributes: algae, weeds - Algae, Aquatic Weeds

Distribution_Liability:
It is emphasized that the GIS layers are graphic representations of the 303(d) list. Where the 303(d) list and GIS representation differ, the 303(d) list takes precedence. The 303(d) list document, "Oregon's Approved 2002 Section 303(d) List" approved by EPA on March 24, 2003 is the document of the record. Users are advised that these layers should not be used without the 303(d) list. There may be both revisions and corrections to the GIS representation without notice. Care was taken in the development of these GIS layers, but they are made available "as is". There are no warranties, express or implied, including the warranty of fitness for a particular purpose, accompanying these layers. Notification of any discrepancies between the GIS representation and the 303(d) list will be appreciated.
