Documentation: WILLRIVR

The WILLRIVR ArcView shapefile provides a link between local observations of 
past events, activities and conditions and their geographic line locations within the 
network of the Williams Creek stream system. The information provided through 
this database was developed primarily through a series of semi-structured 
interviews (or conversations) with long-term residents of the Williams watershed 
area south of Grants Pass, Oregon. This information is linked to a spatial database 
of streams derived from the EPA river reach file. 

There are thirteen separate streams within the database. Each of these streams is 
linked to a separate database record describing the source information and 
providing a link to more detailed textual information. One record includes a link to 
an associated digital photo

Primary Variable Fields

NAME [character]
Name of stream as indicated in the source river coverage (e.g., West Fork 
Williams Creek, Powell Creek, Munger Creek). Thirteen separate streams and 
tributaries are included.

LINK [numeric]
Unique code identifying an individual stream. Several streams in the ArcView 
shapefile have multiple segments, resulting in multiple occurrences of NAME, 
LINK and other associated items that apply to the entire stream.

TYPE1 [character]
Characterization of the general nature of the observation and site. The only 
category in this file is "stream."

TYPE2 [character]
Additional characterization of the general nature of the observation and site. Only 
three categories are used.
	fish
	historic
	trapping

BDATE [character]
Initial approximate year for which observations apply. This field is vacant when 
there is insufficient information from key informants.

EDATE [character]
Last approximate year for which observations apply. This field is vacant when 
there is insufficient information from key informants. Note: the BDATE and 
EDATE fields are the same for single event observations such as floods.

CODES [character]
Alpha-numeric codes representing the conversation or conversations from which 
information for individual records was derived. Information from one 
conversation may be applied to several records, and one record may utilize 
information from several conversations. The codes are developed from a 
combination of the date of theconversation and the initials of the interviewers 
(e.g., 122096PRCY, 012197PRCY).

TEXT [character]
Brief textual description of the observation and site. Additional or more detailed 
descriptions are generally available in a related text document (see TXTLNK).

TXTLINK [character]
Path name and document containing detailed text description of observation and 
site. This field can be used in ArcView to "hot-link" the points in the WILLRIVR 
theme to detailed text descriptions. Most, but not all records have associated text 
documents. As written in the table, the ArcView project must be one directory 
below the AG_DATA directory.

	Example: AG_DATA/DATA/TXTLNK/str112.TXT
	where AG_DATA/DATA/TXTLNK is the path to the TXTLNK directory 
	within the DATA directory within the AG_DATA directory, and 
	str112.TXT.txt is the text document within the TXTLNK directory related 
	to the record for LINK 112.

PHOTOLNK [character]
Path name and photo file related to the observation and site. This field can be used 
in ArcView to "hot-link" the points in the WILLRIVR theme to relevant photos. 
Not all records have associated photos. As written in the table, the ArcView 
project must be one directory below the AG_DATA directory.

	Example: AG_DATA/DATA/PHOLNK/DGRAY1.GIF
	where AG_DATA/DATA/TXTLNK is the path to the PHOLNK directory 
	within the DATA directory within the AG_DATA directory, and 
	DGRAY1.GIF is the text document within the PHOLNK directory related 
	to the subject record.

------------------------------------

The field data were collected under the direction of Interrain Pacific between 
October, 1996 and March, 1997 as part of a local knowledge development pilot 
project. Local knowledge is defined here as site-specific information derived from 
individuals--regardless of position, education or credential--who, by nature of 
their residence, work or activity have made direct observations of resource 
conditions, events and activities within a specific geographic area of interest. The 
database was developed by Interrain Pacific in May, 1997.
