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 1,021 sites:
Columbia Basin | Is Equal To | Yes | AND | ||
State | Is Equal To | ID | AND | ||
HUC 4 Code (Subbasin) | Is Equal To | 17060101 |
Columbia Basin | Is Equal To | Yes | AND | ||
State | Is Equal To | ID | AND | ||
HUC 4 Code (Subbasin) | Is Equal To | 17060103 |

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: | 1,021 |
Number of sites after generating the GRTS sample: | 1,021 |
Number of oversamples: | 521 |
Number of panels: | 1 |
Number of strata: | 1 |
