Quagga and Zebra Mussel Infested and Detected Waters
This map shows where Quagga and Zebra Mussels have infested or been detected in Bureau of Reclamation reservoirs or facilities. Infestation means that colonies of adult mussels have been found and confirmed to be growing and reproducing. Detection means that microscopic Quagga or Zebra Mussel larvae have been detected through testing of waters by the Bureau of Reclamation using cross-polarized light microscopy, scanning electron microscopy, and DNA testing. The presence of microscopic mussel larvae does not necessarily mean that a water body will become infested with adult mussel colonies.
