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 7,914 sites:
Target Population
Streams in Lane County
<none>
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.
Attribute | Values In Frame | ||
---|---|---|---|
HUC_8 | 2 Values: 17090004; 17090002; 17100301; 17090001, 17100303; 17090003; 17100205; 17100206; 17100207; 17070301 |
