Title:

Coastal Cutthroat Trout Headwater Basins in Western Oregon

Description:

Abstract:

This data set is an ArcView polygon shapefile representing headwater watershed areas upstream of barriers to salmonid migration which isolate populations of Coastal Cutthroat trout. The layer was derived from digital elevation model data using ArcInfo hydrologic modeling tools. The data set is in the UTM coordinate system using NAD27.

Purpose:

The data set was developed to provide the basis for a sampling protocol in a study of resident trout populations in western Oregon.

Analytical_Tool:

Analytical_Tool_Description:

The GIS Weasel is a graphical-user-interface (GUI) driven tool that is being developed as an aid to modelers in the delineation, characterization, and parameterization of modeling response units (MRUs) for use in distributed or lumped parameter physical process models. MRUs are defined here as land surfaces that are delineated within an application area, typically a watershed, to reflect a model's treatment of spatially distributed characteristics. MRUs can be treated as homogeneous or heterogeneous with respect to some or all of these characteristics. The interface does not require user expertise in a geographic information system (GIS). The user does need knowledge of the model that will use the output from the GIS Weasel. The interface currently uses Arc/INFO and the Arc Macro Language (AML), as well as Unix shell scripts, awk and C subroutines. Applications require an Arc/INFO grid of a digital elevation model (DEM) that contains the area of interest. A set of watershed boundaries are automatically delineated from the grid of the DEM. A watershed may be selected as the application area from this set or derived on the basis of a user-digitized point. After the application area is determined, the user is asked for the minimum drainage area needed to support a channel. This value controls the density and configuration of the delineated drainage network. Summary statistics and iterative trials allow the user to experiment before choosing the final value. Once the basin and drainage network are established, MRUs can be delineated according to one of several different methodologies: 1) fixed interval grids; 2) irregular polygons; and 3) non-contiguous pixels. A menu for examining and modifying the MRU map and its attributes is provided. Data derived from the original elevation grid (e.g.; slope, aspect) or other grids of other data (e.g.; vegetation, soils) can be examined on the basis of MRU, grid cell, or attribute. The statistical distribution of an attribute within single MRUs or groups of MRUs can also be shown. MRUs can be grouped, divided, or eliminated. The GIS Weasel provides version control and documentation to track modifications of MRU maps. Once MRUs are defined, selected model parameters can be generated using MRU attributes and their statistical measures.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: Values were checked against field data reports

Logical_Consistency_Report:

Data set is an ArcView polygon shapefile, which by definition has closed polygons and associated attribute information.

Completeness_Report:

Watersheds were generated using a threshold area of 500 hectares. The data processing did create some basin areas that were smaller than 500 ha., which were eliminated. Any internal basins were also eliminated (even if the met the area criteria). Only areas west of the Cascade crest were included in the data set. Since digital elevation model data processing in ArcInfo breaks down in flat areas, the Willamette Valley near the mainstem of the Willamette River was not included in the data set. Only basins upstream of barriers to salmonid migration, which had isolated populations of Coastal Cutthroat Trout and no introduction of salmonid species were included in the final data set.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Base data layers meet the national map accuracy standards for horizontal accuracy. However, since data processing included a raster to vector conversion of 30-meter grid cells, we must conclude that horizontal accuracy is no better the +/- 30 meters.
