  1. New Mexico Watershed Watch School Name

  2. What is a watershed?

  3. What is a watershed?

  4. What is a watershed?

  5. What is your watershed address?

  6. What types of connections exist within watersheds? • Community settlement often near water sources • Surface water and groundwater • Upstream and downstream

  7. Surface Water and Groundwater Connections

  8. Hydraulic Conductivity

  9. Surface Water and Groundwater Connections • Septic tanks can pollute groundwater • Over-pumping from wells can diminish water in streams

  10. How might upstream users impact downstream users?

  11. How might upstream users impact downstream users?

  12. Watershed Management • How do we assess and learn what is happening in our watershed? • How do we test if the watershed is healthy?

  13. Chemistry • Turbidity • Temperature • pH • Total Dissolved Solids (TDS) • Nutrients (Nitrogen and Phosphorus)

  14. Turbidity • Measurement of how clear or cloudy water is depending on suspended solids. • How much light is able to pass through?

  15. Temperature • Why is water temperature important to fish or other aquatic life?

  16. pH • Acidic vs basic • Pure water = pH of 7.0 • Rainwater = pH of 5.6 • pH of 6.6 to 8.8 is optimal for most species

  17. Total Dissolved Solids (TDS) • Inorganic salts (calcium, magnesium, bicarbonates, etc) • Organic matter • Hard vs Soft water • We measure TDS by looking at how water conducts electricity

  18. Nutrients • Nitrogen • Phosphorus • Too much nutrients cause algae blooms • When the algae die, oxygen gets too low for fish

  19. Biology • Benthic macro-invertebrates • Vegetation diversity • Vegetation buffer width

  20. Benthic Macro-invertebrates (water insects) • Benthic = “bottom dwelling” • Invertebrate = “without a spine” • Some water insects are very sensitive, they can’t handle pollution they tell us if the water has been clean

  21. Vegetation Diversity and Buffer Width • Shading • Filtration of erosion and other pollutants • Bank stabilization • Improved habitat

  22. Physical • Stream-flow/Discharge • Distance of river to nearest disturbance • Rock embeddedness

  23. Stream-flow • How much water (volume) is passing a point in time. • Cubic feet/sec; Cubic meters/sec

  24. Stream-flow

  25. Monitoring at Frijoles Canyon • What is the condition of surface water in Frijoles Canyon at Bandelier National Park?

  26. Monitoring at Frijoles Canyon • Temperature • Turbidity • pH • Total Dissolved Solids • Nutrients • Riparian habitat assessment • Benthic macro-invertebrates • Streamflow

  27. Monitoring at Frijoles Canyon • Warm clothing • Good shoes • Water bottle Have fun & be safe!
