25 volunteers joined the Upper Sangamon River Conservancy (USRC) Saturday morning as they combed the Sangamon River between the Izaac Walton Cabin and the covered bridge at Lake of the Woods Forest Preserve.
The USRC searches different spots in the Sangamon River annually to study mussels native to the area. The last study in this area was in 2012.
While the total number of mussels found during a total of 25 man-hours remained consistent at 310, the group did find two new species to the site: a Threehorned wartyback and a Fawnsfoot.
The most prominent species found was the Pimpleback at 108.
Overall, the group has found 623 mussels in this area.
