Calling all pirates for a FREE Aquifer Adventure!

Aquifer Adventure

Join us September 16th from Noon – 4 PM at Aquifer Adventure for an afternoon of piratical fun.

Big and little pirates alike are invited to this free family festival all about groundwater, with free T-shirts for the first 300 kids!


Activities include:

  • A treasure hunt
  • Canoe rides
  • Face painting
  • Hands-on science activities
  • Ice cream
  • and much more!

This event is full of hands-on fun that gives participants of all ages the chance to learn about hidden treasure – not gold, but groundwater, a precious resource that flows below your feet! Come dressed in your finest pirate togs, or just learn to speak like a pirate when you arrive.


The Portland Water Bureau and the Columbia Slough Watershed Council have teamed up to bring you this interactive Saturday afternoon. Educators will help young scientists navigate a larger-than-life aquifer and learn the obstacles that water travels through on its way to our drinking water supply. Young pirates will make their own edible aquifers and discover how delicious learning can be. Families can make a household cleaner that really works and is a green alternative to harsh chemicals. Everyone can take a ride on a pirate ship (disguised as extra-stable canoe bi-marans) and voyage in search of a treasure island.

The trips provide safe fun for the whole family on the slow-moving Columbia Slough. We’ll provide the canoe, life jacket, paddle, and a canoe captain to steer – you provide the paddling muscle and curiosity to enjoy the water, plants, and wildlife from the best seat possible. Visitors can make their own pirate hats and other crafts, enjoy face-painting, and more.

Aquifer Adventure is sure to bring out the pirate-scientist in you!

FREE! No registration required. Food will be available for purchase. All activities (including 15-minute canoe rides) are free and available on a first-come, first-served basis.

More about Portland’s Groundwater

Groundwater from the Columbia South Shore is a secondary source of drinking water for Portland and is a critical component of the region’s drinking water system. Groundwater is used to help meet higher summer water demands and to provide water during emergencies or when Portland’s primary drinking water source, the Bull Run watershed, is not available.

This event is a part of the outreach efforts of the Portland Water Bureau’s Groundwater Protection Program. The Cities of Portland, Gresham and Fairview have implemented this program to protect the Columbia South Shore Well Field – a drinking water source for over 900,000 Oregonians. One of the main goals of the groundwater protection program is to educate people and businesses and to prevent chemical spills that could seep into the ground and pollute our drinking water. The cooperation of everyone living and working in the protection area is crucial to keeping our drinking water safe. For more information on groundwater protection visit:
