Water Quality

SCIWC staff have been collecting water quality data throughout the St Croix Watershed since 2017. Our data can be found on Atlantic DataStream. 

Fish Tagging

  In 2018 and 2019 SCIWC staff lead a study on the ability of river herring to migrate through Moosehorn NWR in Maine. 
  The ability of fish to pass through structures on the reserve was determined thorough the use of RFID tags implanted in alewife and blueback herring. 

Fish Count

The SCIWC has been responsible for the Milltown fish count from 1991 to 2011 and 2015 to 2019. 
Counts of river herring going back to 1981 are available in the link provided.
