- Description:

- Abstract:
-
This data set is an ArcInfo polygon coverage depicting analysis subbasins for a Coastal Cutthroat Trout distribution study in Western Oregon. Subbasins were delineated within each of five study basins with the use of ArcInfo hydrologic modeling tools and hand-edits.
- Purpose:
-
Analysis basins were designed to serve as templates in a series of grid analyses performed on exisiting GIS layers. The resulting watershed "profiles" will be used to investigate relationships between Coastal Cutthroat Trout distribution and habitat on a landscape-wide scale.
- Supplemental_Information:
-
To facilitate processing, subbasins were delineated one study basin at a time, resulting in five separate coverages. The final coverages were then appended together to produce this data set.

-
- Attribute_Accuracy_Report:
-
polygons were labeled with item BASIN_CODE in ArcView and checked for completeness; BASIN_CODE values were compared to stream segment numbers in the same view to verify accuracy.
- Logical_Consistency_Report:
-
coverage was built for polygon topology in ArcInfo using BUILD or CLEAN; label errors were checked using LABELERRORS
- Completeness_Report:
-
Within a given study basin, analysis basins were delineated to (1) each routed (surveyed) stream segment and (2) non-surveyed drainages larger than 40 ha. All study basins are headwater watersheds supporting isolated populations of Coastal Cutthroat Trout. Study basins were randomly selected from a larger pool of computer-generated basins representing three ecoregions (Cascade, Klamath, Coast Range) and two erosion potentials (igneous/sedimentary origin).

Line work for study streams was developed from various sources and prepared using the ArcInfo dynamic segmentation process to attach fish habitat survey data to the line work. Stream segments as delineated in this data layer were used as the basis for sub-basin "pour points".

(2) create line coverage HYDRO_XXX
(A) clean raw HYDRO coverage as necessary; check for errors and unsplit all arcs
(B) delete arcs downstream of survey start point
(C) tag all basins draining into non-routed stream segments with an arc from the raw hydro layer; this includes basins pouring into survey end points as well as non-surveyed tributaries off of routed stream segments
(D) digitize segment breaks off of routed stream coverage; save as point coverage (POINTS)
(E) using POINTS as a backcover, split arcs from HYDRO_XXX at each segment break

(6) edit BASINS coverage
(A) all basins must meet one of the following two criteria:
(i) basin is delineated to a routed stream segment; OR
(ii) basin represents a non-surveyed drainage larger than 40 ha DELETE all other basins (polygons)
(B) check all boundaries in final coverage, using a DEM or DRG as a guide
(C) label each subbasin with item BASIN_CODE as follows:
(i) subbasins delineated to a routed stream segment are coded with the stream segment number, omitting any alphabetical characters;
(ii) subbasins representing non-surveyed drainages are coded with a "9" followed by 1 or more digits (90,91...99,910...)
(D) BUILD final coverage for polygon topology and check for label errors
