This sample design is based on master sample: Columbia Basin Master Sample
Details of this master sample:
- Source: U.S. Environmental Protection Agency
- # of sites: 551046
- Type: Linear 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:
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
Target Population
All wadeable streams in the State of Oregon
<none>
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).
