This sample design is based on master sample: Columbia Basin Master Sample

Details of this master sample:



Frame

This sample design started with an initial frame of 551,046 sites, based on its master sample. The criteria (based on the master sample's attributes) were then used to refine the sample frame down to 71,633 sites:

Criteria Group 1
           
  Strahler Order Is Equal To 1 OR
  Strahler Order Is Equal To 2 OR
  Strahler Order Is Equal To 3 OR
  Strahler Order Is Equal To 4
AND

Criteria Group 2
           
  NHD Feature Type Desc Is Equal To StreamRiverPerennial
AND

Criteria Group 3
           
  State Is Equal To OR

Target Population

All wadeable streams in the State of Oregon


Panel designs can help address sampling objectives by increasing the total number of samples at a lower overall cost. A common panel structure involves one or more panels with a high revisit frequency (e.g. an “Annual” panel), and other panels with a lower revisit frequency (e.g. a three year “Rotating” panel).

This design uses the following attributes to create the stratification shown below. Each row in the table represents a stratum. This design’s panels are also shown in the table, even if it uses only a single, default panel.
