available Co resource experts. Use of these lists will help to promote the 

 consideration of all reaches and will ensure consistency between resource 

 categories. As appropriate, river segments will be identified using physical 

 landmarks, coordinates, or other locational information and will be presented 

 in a downstream boundary to upstream boundary fashion. The terras "mouth and 

 "to headwaters" or "source" signify the extremes of this segment description 

 system and may be used as appropriate. If no segment description is given, 

 the entire stream length will be assumed to have consistent resource value. 



Sample data forms are included for each resource value. In addition to 

 segment description, forms will include a notation of map name to enable input 

 of attributes into the proposed Geographic Information System (GIS). As 

 appropriate, preparers will develop a coding system in consultation with state 

 level and regional project management to denote the relative certainty of 

 resource characterizations. Stream segment numbers will be written on the 

 maps to enable easy cross referencing to the tabular data. 



Where resource value is consistent in all upstream tributaries, each tributary 

 need not be evaluated separately. In such situations, the values attributed 

 to the larger segment will be assumed for all tributaries. An asterisk (*) 

 placed after the name of the larger segment will denote this situation. If 

 the river list being used is hierarchical, a diagonal slash drawn through 

 upstream segments could clearly indicate that the segments are being clustered. 



If no notations are made on the data form, it will be assumed that the segment 

 is unclassified or resource value is unknown. A horizontal line across the 

 form signifies resource not present. 



° Maps 



Maps will be used to display river values. Sets of 1:100,000 scale maps and a 

 supply of 1:500,000 scale hydrologic unit maps have been provided to each 

 state coordinator by BPA. Labels have been supplied for each map to be used 

 as legends. Colored pens have also been supplied. 



One set of 1:100,000 scale maps will be used to depict the significance of 

 each of the following resource values. 



Resident Fish 



Wildlife 



Natural Features 



Cultural Features 



Recreation 



Institutional Constraints 



In addition, 1:500,000 scale maps will be prepared for purposes of 

 presentation and review. 



In Oregon, Washington, and Idaho, 50-60 maps will be required per category for 

 each state. Montana will require approximately 100 maps per resource 

 category. Significance will be recorded in colored pen using the following 

 color scheme. Exact names and printing numbers have been included for the 

 standard pens chosen for the study: Berol Prismacolor Art Markers. 



Outstanding or Unique Significance - Red (Crimson Lake: PM-3) 

 Substantial Significance - Orange (Bittersweet: PM-16) 

 Moderate Significance - Gray (Warm Gray 60%: PM-104) 

 Limited Significance - Green (Malachite: PM-32) 

 Unclassified or Unknown - No mark 

 Resource Not Present - Brown (Burnt Ochre: PM-66)
