Area	South Fork Big River
Topic	Sediment: Gravel Permeability from the SF Big River 2000

 

Caption:  The above chart illustrates that mean gravel permeability in the South Fork Big River in the year 2000 was variable between tail-out sites, but four out of the six sites studied showed permeabilities leading to predicted survival indices above 50%. High gravel permeability indicates favorable conditions for incubating salmon eggs and alevins. The red markers display predicted values for percent egg-to-fry survival. This calculated index for survival has had limited testing. See Info Links for more information. Click on Picture for a map of MRC study segment locations.
