Spring 2016 Benthic Monitoring Results

Home » Uncategorized » Spring 2016 Benthic Monitoring Results

FOMR’s spring benthic monitoring was completed on April 16th.  Ten certified monitors and sixteen assistant monitors helped collect the critters and record the data.

Each site monitored receives a “score” – a number between 0 and 12 – from the VA Save Our Streams (SOS) Multimetric Index.  The SOS Multimetric Index score is a representation of the suitability of the stream for aquatic life. The score is determined by the number and kind of aquatic critters found in a water sample. You will find more info on benthic monitoring by clicking here.

  • An SOS Index score of 9 to 12 = Acceptable ecological condition
  • An SOS Index score of 8 = Ecological condition cannot be determined at this time (Gray Zone)
  • An SOS Index score of 0 to 7 = Unacceptable ecological condition

Sites & Scores (all sites are on main stem of Middle River):

Many thanks to the following FOMR volunteers who collected the samples and counted the critters: Pete Cooper, Paul Bugas, Sherry Stanley, Sara Jordan, Ann Cline, Adrie Voors, Chris & Kaylee Kasnosky, Reese Bull, Phillip Davis, Dustin Staton, Rick Chittum, David Fuller, Sandy Calvano, Sarah Long, Mark Battin, Joe Thompson, Steve Cummins, Tom Shapcott, Mike Harmon, Tom Kelley, Haleigh Martin, Wick Vellines, Randy Smith, Darrell Schwalm and Whit Morriss.

Thank you to Kate Guenther for recording the data for FOMR.

Here are some bugs found in the benthic zone (under rocks on bottom of stream) that are very sensitive to pollution.  If a lot of these are found, it’s likely that the site will have a higher SOS Multimetric score.
