why benthic macroinvertebrate monitoring
Why Benthic Macroinvertebrate Monitoring?
  • One way to accomplish the goals set forth in our associations mission statement.
  • To assess the current water quality.
  • To get a better sense of the impact of land use practices on the Pohatcong Creek.
  • To share the collected data with the communities as a tool for planning/land use issues.
pohatcong creek watershed boundary
Pohatcong Creek Watershed Boundary
  • The entire watershed is within Warren County.
  • The creek is approximately 20 miles in length.
  • Flows through 7 municipalities on its way to the Delaware River.
  • Approximately 58 square milesof land comprises the watershed.
initiating the monitoring program
Initiating the Monitoring Program
  • Develop a Quality Assurance/Quality Control [QA/QC] document
  • Find and train a group of ‘Water Stewards’
  • Survey and choose monitoring sites along the length of the creek.
  • Establish a 3 year baseline of data.
the qa qc
The QA/QC
  • Drives the program.
  • It ensures that sampling is unified consistent, and replicable.
  • It defines the equipment, sampling intervals, procedures, and analysis.
  • Sampling protocol is based on the U.S. EPA Rapid Bioassessment Protocol III [EPA/440/4-89/001 May 1989].
the water steward
The Water Steward
  • A group of 10 people established the water steward pool.
  • Each member completed the course “Volunteer Monitoring of Streams & Rivers - May, 1999.
  • The group was divided into 4 teams to cover the 30 sites selected along the creek.
field work
Field Work
  • Letter of introduction
  • ‘Rapid Bioassessment Protocol followed during site work.
  • Benthic macroinvertebrate sample is collected.
  • In addition, stream width, water appearance, odor, temperature, and flow velocity are recorded.
  • The site is sketched and a habitat assessment is performed.
stream assessment monitoring system sams
Stream Assessment Monitoring System [SAMS]
  • Developed and written by one of the members of our watershed association.
  • GIS database management system to record and display the results of the stream monitoring program.
  • Available in two formats - a read only or a read/write version.
sams features
SAMS Features
  • Display detailed analysis of sampling data for each site.
  • Calculate the N.J. Impairment Score versus 6 other features.
  • View site photographs.

SAMS Features (con’t.)
  • Interactive identification utility of benthic macroinvertebrates which are found in our samples.

PCWA Web Site
  • www.pcwa.org
  • Overview of our organization and goals.
  • The sights & sounds of the watershed can be viewed.
  • Also, provides a venue for the transfer of data between the field and SAMS updating.
