Abstract:
The Oregon Department of Fish & Wildlife has been actively acquiring stream habitat inventory information for the purpose of habitat assessment since 1990. This information is collected during the summer months by stream survey crews using methods described in Moore et al. (1997). The field data focuses on channel and valley morphology (stream and reach data), riparian characteristics and condition (reach data), and instream habitat (habitat unit data). The survey data is compiled into a comprehensive database that is used in fish management and planning activities. The data are dynamically segmented in a geographic information system (ArcInfo) onto a 1:100,000 scale digitized stream layer to display habitat features and combinations of habitat features relative to location of streams, reaches, and habitat units in the watershed. The 1:100,000 scale digitized stream layer was originally digitized by the USGS in their PNW River Routes Project. It was later modified by ODFW's GIS Division to include a complete stream routing system. This modified route system provides the basis for our reach and habitat coverages. : The habitat unit dataset provides all of the information collected at the unit level by the stream survey crew. Habitat units are the building blocks of reaches. Each unit is longer than one active channel width and is an area of relatively homogeneous slope, depth, and flow pattern representing different channel forming processes. The channel is classified into 22 hierarchically organized types of pools, glides, riffles, rapids, steps, and cascades. The crews estimate the length and width of every habitat unit. At every unit, attributes are estimated or measured to describe gradient, substrate, woody debris, shade, features of instream cover, and bank stability. The habitat information is distributed along the length of the stream route in relation to the distance of the habitat unit from the start point of the stream.

Purpose:
The stream habitat distribution coverages provide a means for accessing stream data in an electronic medium. It increases the ease of data dispersal and allows for the assessment of basin wide characteristics. It also allows for stream and basin analysis to occur from a spatial scale and perspective.

Attribute_Accuracy_Report:
It is important to remember that the data contained in this dataset reflects the condition of the stream at the time of the survey. Streams are dynamic systems that change with every high or low flow event. Substrate and woody debris move through the system, trees fall into the stream causing changes in flow and habitat type. Pools are formed and filled in annually. It is the purpose of the survey to document the condition of the stream at the time of the survey. This data may be used later for comparison and management planning work. The reach dataset generalizes the habitat units that are surveyed by the crew. It gives an overview of the conditions within the reach or section of stream. It should be a reference point for later comparative work or for the analysis of stream conditions. The habitat dataset includes all of the unit data for the entire survey. It is within this dataset that the most noticeable annual change will occur. There will be changes in the distribution, size and location of habitat types annually. This dataset is not intended to be a map of the absolute distribution of habitat types. Rather, it indicates the condition of the stream at the time of the survey.

Logical_Consistency_Report: Chain-node topology present.
Completeness_Report:
" Not all of the streams on the base HUC (hydrologic unit code) coverages have been surveyed. Surveys are a ongoing process and streams are added to the coverage as they are completed. The coverages are updated when new streams are surveyed. Surveys occur annually, however, new surveys do not occur within every huc drainage annually. Therefore, updates of our coverages does not necessarily occur on an annual basis." Some attributes do not exist on all arcs.

Process_Step:
Process_Description:
The source coverages were acquired from the Oregon Department of Fish & Wildlife's GIS Division. The coverages were originally digitized by the USGS as part of the PNW River Reach File project which digitally entered stream basins based on their Hydrologic Unit Code (HUC) which had been previously defined by the Environmental Protection Agency (EPA). These HUC coverages were completed at a scale of 1:100,000. They were altered by ODFW in order to add unique stream identification numbers (LLID), as well as the addition of two separate route systems. The route systems were created using dynamic segmentation tools and have resulted in one route system composed of streams and another for stream reaches. They were developed to assist in the quantification and enumeration of fish distribution data. In this project, we have taken the routed HUC coverages and dynamically segmented the appropriate streams in order to append our stream habitat data. The process that we use is summarized below:

1. Edit HUC cover routes to reflect the end point of the stream habitat survey. 2. Remeasure the route to the length (in meters) of the survey as determined by the survey crew and the analysis of the data. 3. Create a calibration coverage based on the HUC coverage. 4. Add calibration points which are identified as locations on each streams where we can be certain of the location of the crew. Points include bridge crossings, tributaries or reach changes. 5. Each calibration point is given a distance measure that corresponds to the distance from the start of the survey to that point on the stream. 6. Calibrate the routes on the huc coverage based on the calibration coverage. 7. Import the dbase file that contains the database information for the the reach or habitat datasets. 8. Create an eventsource with the dbase file. 9. Link the eventsource to the routed HUC cover based on the llid field. (The llid is the longitude and latitude of the starting arc of the stream. It was calculated and assigned using an aml by the ODFW GIS Division.) 10. Build the new coverage and create an export file.

Reviews Applied to Data: The data is reviewed before dissemination to the public. The dimensions of the arc attribute files are reviewed to assure that the necessary variables are present and have the correct field values. The reach and habitat datasets are reviewed in ArcView in order to determine that the dynamic segmentation and calibration process have placed certain landmarks in the correct location.

Overview_Description:
Entity_and_Attribute_Overview:
: The habitat unit dataset provides all of the information collected at the unit level by the stream survey crew. Habitat units are the building blocks of reaches. Each unit is longer than one active channel width and is an area of relatively homogeneous slope, depth, and flow pattern representing different channel forming processes. The channel is classified into 22 hierarchically organized types of pools, glides, riffles, rapids, steps, and cascades. The crews estimate the length and width of every habitat unit. At every unit, attributes are estimated or measured to describe gradient, substrate, woody debris, shade, features of instream cover, and bank stability. The habitat information is distributed along the length of the stream route in relation to the distance of the habitat unit from the start point of the stream.
