About Bull Run School Field Trips

Test water quality, tour a 1929 dam, and learn how forests help protect drinking water during this full-day school field trip. We offer school field trips in May, June, September, and October. We also offer Bull Run tours in the summer and fall for anyone who wants to sign up as an individual or with a small group.

For more information, or to request a field trip for your class, please contact Briggy Thomas (, 503-823-7407).

Here’s a typical field trip leaving from a central Portland school:

School starts       Meet at your school, board the bus

                            Spend the 90-minute bus ride learning about Portland's drinking water system

                            Eat lunch

                            Do three activity rotations:

                                 -Test the turbidity (a water quality measurement) of reservoir water

                                 -Walk in the forest and learn about how it helps protect water quality

                                 -Tour the city's 1929 concrete dam

                            Board the bus

School ends        Arrive at school

Here are some essentials to be aware of:

  • The tour area is remote. Water Bureau staff carry emergency radios and are trained in first aid; however, cell phones do not work and emergency care can be more than an hour away.
  • Restrooms can be up to 2 hours apart. Please contact us if limited restroom availability presents a challenge.
  • Smoking/vaping/e-cigarettes are not allowed.
  • We offer the field trip for grades 3-12 (we also offer tours for adults, including college students).
  • We can accommodate one class (25-30 students), plus about 6 chaperones and a teacher, on each field trip. Everyone must travel together on one bus.
