Probabilistic Sampling – Probabilistic Sampling – ‘Randoms’‘Randoms’
Provides statistically valid estimates of condition.
• There are over 10,000 streams identified in WV.
• Between 30,000 and 50,000 stream miles.
• We can’t sample them all.
![Page 23: Watershed Assessment Section John Wirts Watershed Assessment Section March 17, 2009](https://reader036.vdocument.in/reader036/viewer/2022062417/55156ca555034691418b4f17/html5/thumbnails/23.jpg)
Probabilistic Sampling - continuedProbabilistic Sampling - continued
Started random program in 1997, completed 1st round in 2001.
Round 2: 2002-2006 Changed from rotating basin to statewide approach. Instead of getting all 30 or 35 sites from a specific watershed in one year, we’re getting 5 or 6 samples in each of the 5 years.
In April we will be starting year 3 of the 3rd round
![Page 24: Watershed Assessment Section John Wirts Watershed Assessment Section March 17, 2009](https://reader036.vdocument.in/reader036/viewer/2022062417/55156ca555034691418b4f17/html5/thumbnails/24.jpg)
State of the Streams Report
Data from 1st 2 5-yr rounds has been crunched
Condition estimates (% stream miles impacted) for:
• Biologically impaired• Several habitat measures• WQ condition estimates (acid precip, AMD, ++)
Estimates completed for 8-dig HUC w’sheds, Level 3 Ecoregions, and statewide

Round Three – entering 3rd year of R3
• Fewer sites (75/yr instead of 150)
• Will be able to report on condition at ecoregion level
• Will include fish at ~30 sites / year

Representative sites: including major tributaries & HW
Resample sites where use attainment questionable
