Slough Stories

Tuesday February 10, 1:48pm

The Columbia Slough Watershed Council celebrates its 20th anniversary this year and there are a thousand stories to tell. This video is a compilation of a few of the stories told at the Slough Stories event in November 2014. This is part of an effort to document efforts large and small that have improved the Columbia Slough watershed and raised public awareness of the waterway and the region. Enjoy this trip down memory lane (or should we say a paddle down memory slough).

Aquifer Adventure -  a Piratey Sucess!

Monday September 22, 10:06am

On Saturday, September 12th over 500 pirates of all ages joined the Portland Water Bureau and the Columbia Slough Watershed Council for an event like no other, a pirate-themed groundwater education festival. Now in its thirteenth year, Aquifer Adventure teaches families about our underground treasure - not gold, but groundwater, a precious resource that flows below our feet!

The event featured a groundwater obstacle course, water conservation activities, information on green household cleaners, edible aquifers made from ice cream, canoe rides on the Columbia Slough and more. Attendees also had the chance to explore a drinking water well site and learn how a real aquifer works from Portland Water Bureau experts.

What makes groundwater so important?  Groundwater from the Columbia South Shore Well Field 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. Having a back-up water supply source also helps the City avoid having to build and operate an expensive water filtration plant for the Bull Run source.

Aquifer Adventure 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 about how to prevent pollutants and chemical spills from seeping into the ground where they could impact our drinking water. The cooperation of everyone living and working in the protection area is crucial to keeping our drinking water safe. 

Over the past twelve years, over 4,000 attendees have learned about the importance of groundwater through this free event. The response from participants has been overwhelmingly positive. It’s exciting to see connections even a three year old can make about where their water comes from. And of course, it’s fun to dress up like a pirate. There’s nothing like putting on an eye patch and bandana to get you excited about groundwater!
