Event Details

Join representatives from the City of Austin Watershed Protection Department, Austin Youth River Watch, Lower Colorado River Authority, and Keep Austin Beautiful as we explore Barton Creek near Lost Creek Blvd to learn how professionals monitor water quality.  This is a great opportunity for anyone interested in Environmental Science as a career or just for fun.

Come prepared to hike and for hands-on education.  Wear comfortable clothes, closed toed shoes, and bring a bottle of water.


Environmental Scientist, Todd Jackson, will talk about a variety of things that are evaluated when studying water quality (there will be a heavy emphasis on macroinvertebrates):

1.  Contact Recreation - E. Coli Bacteria

2.  Non-Contact Recreation - Visual assessment form

  • Aesthetic appeal to average person
  • Garbage, odor, algae, clarity, etc

3.  Water Quality - Chemical measurements

  • Nutrients (Nitrate-N, Ammonia-N, and Orthophosphorus
  • Total Suspended Solids and Turbidity
  • Dissolved Oxygen, Conductivity, pH and Temperature

4.  Sediment Quality - Sediment Chemistry

  • Sampled at mouths of streams once per year
  • Aggregates watershed inputs
  • Metals, PAHs, pesticides and herbicides

5.  Habitat Quality - Forms based on visual assessment and direct measurements

  • EPA national protocol, qualitative
  • Non-scoring Pfankuch channel stability form

6.  Aquatic Life

  • Benthic Macroinvertebrate Community (invertebrates)
    • 9 metrics assessing: Diversity, Pollution Tolerance and Community Structure
    • Evaluates stream health in terms of the preceding months to years
  • Diatom Community (single cellular algae on rocks)
    • Pollution Tolerance Index and Percent Similarity to Reference Conditions
    • Evaluates stream health in terms of the preceding months to years
