Aquatic Biomonitoring

DSC_0020

bill in streamSince 1990, Biomonitoring Program Director Dr. William O. McLarney and thousands of volunteers have been monitoring the Little Tennessee River basin. In those 25+ years, monitoring has occurred on more than 150 sites, generating the largest fish-based biomonitoring database in the world for any comparable sized watershed.

The Aquatic Biomonitoring season runs from late May until early August. Click here to learn more about volunteering with this program.

Biomonitoring sometimes uncovers potential problem areas, but Dr. McLarney also argues that “boring is good.” Read why here.
