Making a Difference in Maryland Waters


Volunteers agree to participate in a one day training session and then spend about two more days during the March-April sampling window collecting aquatic invertebrate samples from stream beds.

Training consists of four basic parts:

  • classroom instruction,
  • GPS familiarization,
  • actual sample collection practice (Bring your waders!),
  • and choosing your watershed to sample
