imageStreamWatch Data updated through 2005!

Monitoring the stream
Since 1992, dedicated volunteers have continually assessed and documented water quality in the Millstone Watershed through the Association’s StreamWatch Program. StreamWatch focuses on measuring the health of local water quality through visual, biological, and chemical observations. StreamWatch data is better enabling the Association to assess the impacts of pollution on local streams and determine actions necessary to protect and improve water quality for everyone.

Becoming a StreamWatch volunteer is an easy and fun way to contribute to the health of your watershed. The Association relies on dedicated volunteers, like you, to assess water quality throughout the Watershed. Volunteering requires an initial half-day training session and a one-year commitment.  Take a look at the StreamWatch section to see what the different monitors do and volunteer today! Contact Beth April at bapril -at- thewatershed.org or 609 737 3735.

The StreamWatch program is successful in determining water quality because it strives to involve citizens in observing, monitoring, recording, and reporting stream conditions, to motivate the public to initiate change in their use of the land and drainage systems and to provide quality data to decision-makers to bring about improvement in water quality.

The Association launched its comprehensive water quality monitoring program in response to a state report that indicated the overall water quality of the Millstone Watershed was “fair.” The report showed that some waters were in violation of the New Jersey State Water Quality Standards for stream health.  Using StreamWatch data collected over several years of monitoring, we are assessing the impacts of point and nonpoint-source pollution on local streams.

  • Marked the 10th anniversary of StreamWatch in 2002 by compiling the first 10 years’ worth of data. Check out our StreamWatch data to see if our streams are healthy or degraded.
  • Utilized water data from our StreamWatch program into our Watershed Assessment work.
  • Reported on the health of Cruser Brook to Montgomery Township so that stormwater impacts from the 3M Quarry in Belle Mead could be addressed in 2002 and 2003.
  • Sent our visual assessment protocols to The Passaic River Coalition in the summer of 2003 so they could measure the amount of erosion along the Passaic River within Passaic County.
  • Answered a request by the South Brunswick Environmental Commission for visual assessment data on Heathcote Brook in May 2003, so they could determine the health of streambanks and extent of erosion in their town.
  • Submitted data to the U.S. Army Corps of Engineers for a multi-agency project to determine and restore the environment around and including Carnegie Lake.  Data from the chemical assessment (StreamWatch) program on the Lake, Heathcote Brook, Harry’s Brook, Big Bear Brook and Devil’s Brook will supplement information gathered by project consultants, which will be developed into an ecosystem restoration plan.
  • Submitted water quality data to the project consultant for the Millstone Bypass in the fall of 2002.  Data was reviewed for inclusion into an Environmental Impact Statement.
  • Developed a database for visual assessment information in 2003 to be used in determining sites for our restoration program.
