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 11,943 sites:

Criteria Group 1
           
  Columbia Basin Is Equal To Yes AND
  Is Target in CHaMP Is Equal To 1

Target Population

Chinook and Steelhead ESUs above Bonneville Dam. 


<none>

Below is the complete list of sample sites that were drawn using the criteria for this sample design.

Number of sites before generating the GRTS sample: 11,943
Number of sites after generating the GRTS sample: 2
Number of oversamples: 1
Number of panels: 1
Number of strata: 1
