Since the early 1990s, Nature Forward Water Quality Monitoring Program has operated throughout Montgomery County, Maryland, and in parts of the District of Columbia. We also host sites in Howard and Prince George’s Counties, MD. We provide our data to government agencies and to others upon request.
How It Works
Teams of volunteer monitors visit stream sites in April, July, October, and optionally during the winter. They conduct habitat assessments and collect and identify “benthic macroinvertebrates,” small organisms that live in the streams. Because these organisms exhibit a range of sensitivities to pollutants and stressors, they help us determine the streams’ health. Our program is distinct in that our monitors identify aquatic insects to the taxonomic level of family. This gives us a clearer picture of aquatic diversity and stream health than more general identification practices. Our program is also unique in that monitors learn to identify the organisms in the field and then release them alive, rather than preserving them in alcohol and sending them to a lab for identification.
Each team has a designated leader who is certified in identification. New volunteers are teamed with experienced monitors at stream sites convenient to them. Our water quality classes give volunteers the information they need to monitor. See what it’s like–check out the video below!

Become a Volunteer Water Quality Monitor
Before going into the field, new monitors should have a basic knowledge of macroinvertebrate identification and stream ecology, either from previous training or by attending Nature Forward’s water quality classes. Volunteers should also be willing to commit to at least two seasons of monitoring.

Reports & Data
Where We Monitor: see a map of all our water-quality monitoring data. It shows all of our sites that have been monitored in the last five years. Click a site’s microscope icon to see a full list of organisms collected in the last monitoring session and its most recent stream health score (once it’s been quality-reviewed). At the bottom of the pop-up, click “Stream Health Over Time” to see a chart of spring Index of Biotic Integrity (IBI) scores graphed over time.
Download Nature Forward WQM Data: The Chesapeake Monitoring Cooperative (CMC) hosts our data in its Chesapeake Data Explorer, where it is packaged for download in a consistent format with other volunteer-collected water quality data and made available to the public and state & federal agencies. Visit the Chesapeake Data Explorer’s Query Page, set the Data Type to “Benthic Macroinvertebrates,” and then set the Group to “Nature Forward.” You can filter further by site (Station) and time period. Data availability in CMC is updated at the end of each calendar year.

Self-Paced Online Stream Science Classes
For 30 years, Nature Forward has been teaching the natural history of aquatic ecology and training volunteer stream monitors who track the health of our region’s streams. Learn from the experts: study stream science in our introductory classes, and you just might be inspired to become a stream monitor yourself!
Stream Science Introduction: Part 1: Healthy Stream Biology*. An introduction to monitoring and non-insect macroinvertebrates. Part 2: How to Read Your Stream*. Learn about the influence of land uses on streams, stream character and dynamics, bank erosion, bar formation, substrate composition, different velocity-depth regimes, and the importance of riffles and riparian vegetation. *These classes are recommended for all volunteer monitors and those interested in joining the program.
Advanced Macroinvertebrate Identification Series: Our advanced classes are perfect for those interested in deepening their knowledge about biological stream monitoring and are taught by instructor Cathy Wiss. Each class runs 45 – 70 minutes and includes extensive photos and videos collected by our own monitoring volunteers and staff, plus several carefully curated recommended videos from other sources. Classes include: Caddisflies; Beetles; Megaloptera, Hemiptera, Lepidoptera; True Flies; Damselflies and Dragonflies; Mayflies; Stoneflies. Bonus review session included if you sign up for the full series (15% discount for entire class series ($170 non-members / $102 members, includes a bonus review session).
