The details of this Sample Design, including all the parameters used to generate it, are included below. Sample designs must belong to a Monitoring Project which may be associated with a Monitoring Program.

Description

Ecology's Environmental Assessment Program’s Status and Trends Monitoring for Watershed Health and Salmon Recovery (WHSR) project collects data on river and stream health by region. Approximately 350 sites are sampled every four years.

Sampling Schedules for Watershed Health Monitoring​ explains the monitoring-sites rotation, sample design, and contains the latest Candidate Site List.

Latest River and Stream Monitoring for Watershed Health explains where Ecology staff are working during the monitoring season.

WSHR also offers services to the public for objectively assessing watershed health. These include standard protocols for monitoring rivers and streams, training on these protocols, the Washington Master Sample site set, and the STREAM database for managing stream habitat data.

This sample design is based on master sample: Washington Statewide Master Sample

Details of this master sample:



Frame

This sample design started with an initial frame of 387,237 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 14,212 sites:

Criteria Group 1
           
  Land Owner Name Is Not Equal To US Federal Government
AND

Criteria Group 2
           
  Frame Evaluation Is Equal To non-target OR
  Frame Evaluation Is Equal To pending OR
  Frame Evaluation Is Equal To target

Target Population

<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).

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.
