Stream Monitoring and Stewardship Program Details

WATERSHED MODEL DEMONSTRATION/DISCUSSION

Grade Level: 5th – 12th

Time Required: 1 – 1 ½ hours

Description: This interactive table-top model by Enviroscape® is designed to introduce key watershed concepts including the definition of watershed, types and sources of pollution, effects of pollution on humans and ecosystems, the differences between non-point and point source pollution, and best management practices.

STUDY DESIGN AND EQUIPMENT/METHODS DEMO (MANDATORY)

Grade Level: 5th – 12th

Time Required: 1+ hour

Description: It is imperative that students understand the scientific method and identify the monitoring question driving the field study before collecting data.  Introducing the study design and the methods that we’ll use in the field will increase the quality of the data collected and help to ensure that the field experience goes smoothly and efficiently.  One of several options for covering these topics are self-paced exploration stations (see program handbook for additional information).

INTRODUCTION TO WATERSHED AND WATER QUALITY MONITORING  

Grade Level: 7th – 12th

Time Required: 30 minutes – 1 hour

Description: This PowerPoint presentation covers the definition of a watershed, effects of imperious surfaces on the water cycle, benefits of healthy watersheds, reasons why we monitor water quality, and an introduction to aquatic ecology and water quality parameters.

HABITAT/PHYSICAL ASSESSMENT

Grade Level: 5th – 12th

Time Required: 1 hour

Description: Monitoring physical characteristics of the river can provide a context for evaluating chemical and biological parameters, and can be the simplest and most effective way of evaluating a river’s health if time and resources are limited.  It can also be useful to compare physical assessments from year to year to understand the dynamics of a river system.  Physical parameters include stream depth and width, velocity, substrate, and turbidity.

CHEMICAL MONITORING                                               

Grade Level: ​5th – 12th

Time Required: 1+ hour (for all parameters)

Description: Chemical monitoring allows us to view water quality parameters for a snapshot in time.  Collecting chemical data can be useful for identifying areas for further investigation, and can help students better understand the differences between and interactions of abiotic and biotic components of an aquatic ecosystem.

 

The station can include the following parameters:

pH (10 minutes)-Equipment/Methods: Hach pH test strips

Dissolved Oxygen (20 minutes)-Equipment/Methods: Hach Dissolved Oxygen Test Kits (Winkler Method); YSI 85 Meter

Phosphorus (15 minutes)- Equipment: Hach Pocket Colorimeter II Test Kit

Conductivity (10 minutes)- Equipment: YSI 85 Meter

BENTHIC MACROINVERTEBRATE SAMPLING                                                           

Grade Level: ​5th – 12th

Time Required: 1+ hour for Streamside Survey; 4 hours for intensive laboratory inventory

Description: In the Streamside Survey Method all work is done in the field.  This involves collecting the sample using a net, sorting and identification of major groups (mostly orders, a few families, some classes) of benthic macroinvertebrates, and assessment of primary habitat characteristics. Approximately 0.28 square meters of the stream bottom are sampled.  The relative abundance and richness of the each major group is determined, a field sheet is filled out, and the organisms are returned to the stream.

MICROBIOLOGY

Grade Level: 5th – 12th

Time Required: 10 minutes (sample collection), 24 – 48 hours (sample processing)

Description: We use the Quanti-Tray method to quantify Total Coliform and E. coli.  A 100 ml water sample is collected in the field, kept on ice, and processed in the lab no longer than 6 hours after the sample was collected.  We use two different nutrient reagents: Colilert, which is E.P.A. certified for testing ambient waters and has an incubation time of 24 – 28 hours; and Colisure, which is not E.P.A. certified for testing ambient waters (it’s E.P.A. certified for testing drinking water), but has an incubation time of 24 – 48 hours.  We will email your results.

OUTREACH/STEWARDSHIP PROJECT (MANDATORY)                            

Grade Level: 5th – 12th

Time Required: varies

Description: UVM Watershed Alliance emphasizes action based on unbiased scientific information.  The Community Outreach/Stewardship component allows students to utilize their creativity while they extend their findings to and become engaged in their local community. 

Community Outreach: Program participants have presented their findings to local planning commissions, school boards, watershed groups, and parents.  Other Community Outreach projects have included the production of a series of public service announcements broadcasted on the radio, brochures, websites, and participant led lessons for younger students. 

Conservation Service/Stewardship: Opportunities exist to partner with community organizations to implement on the ground conservation service or stewardship projects.  UVM Watershed Alliance can assist your class in identifying a meaningful project and establishing a partnership with the appropriate community organization.  Examples in the past have included riparian tree plantings, invasive species removal and clean-up days.
