  1. BENTHIC MACROINVERTEBRATE STREAM MONITORING Water Steward Program

  2. 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.

  3. 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.

  4. 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.

  5. 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].

  6. 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.

  7. 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.

  8. 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.

  9. SAMS Features • Display detailed analysis of sampling data for each site. • Calculate the N.J. Impairment Score versus 6 other features. • View site photographs.

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

  11. SAMS Features (con’t.) • Virtual tours of Stream Monitoring, the Watershed, or Historical Areas

  12. 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.
