Sample Design: Piscivorous Fish Status and Trend Monitoring in the Columbia River Upstream of McNary Dam
  • ID: 16609
  • State: Finalized
  • Owner: Matt Polacek
  • Spatial Design Category: Generalized Random Tessellation Stratified (GRTS), External
  • Sites in Design: 32
  • Has Location Privacy: No
  • Data Repository: PTAGIS Website (See Sample Design Overview for full list)
  • Version History: v1.0 Finalized (9/25/2020)

The details of this Sample Design, including all the parameters used to generate it, are included below. Sample designs must belong to a Study Plan.


A GRTS sample will be obtained for sites along each bank of the river that can be effectively sampled using a boat electroshocker.  The length of sties will initially be based on the observed or expected bass density (i.e., low, moderate or high), but consistent within each strata. Minor adjustments to the site location may also be necessary to ensure each sample site encompasses an adequate area.
