Cycle the Well Field on June 9

Cycle the Well Field cyclists

Join the Portland Water Bureau and the Columbia Slough Watershed Council for a FREE bicycle tour through Portland’s Columbia South Shore Well Field!

Located deep below the Columbia Slough Watershed, the City’s well field is capable of producing close to 100 million gallons of high-quality drinking water per day. The well field is used as an emergency backup for the Bull Run source and to augment our water supply during the summer when demand for water is higher.

Refreshments will be provided. Space is limited so register early!

The Ride

At several stops along the ride, experts from the Portland Water Bureau and the Columbia Slough Watershed Council will reveal the mysteries of groundwater, discuss how groundwater provides flexibility and reliability to the City's water supply, and explain how we can all have a role in protecting this important resource.

The ride will cover approximately 16 miles over relatively flat terrain, at a slow to moderate pace. This event is suitable for advanced, beginner, and intermediate riders due to the length and possible headwinds.

Bring your bike, helmet, water bottle and lunch. This event is rain or shine, please dress for the weather!
