Great Slough Clean Up - Johnson Lake

Volunteer Event
Join PP&R and the Columbia Slough Watershed Council to clean up litter and remove ivy at Johnson Lake property

Join PP&R and the Columbia Slough Watershed Council (CSWC) to help clean up litter and remove invasive ivy from the unique Johnson Lake property. 

Each year, the Columbia Slough Watershed Council hosts the Great Slough Clean Up, a day when volunteers gather to clean up multiple sites along the Slough all at once to make a GREAT impact.

This year, CSWC is holding Great Slough Clean Up events on Saturday, August 15th from 9am-12pm and Thursday, August 27th from 5-7pm at two Portland Parks: Kelley Point Park and Johnson Lake property.

Volunteers are asked to bring their own face coverings and to wear them during the event, however PP&R will provide extra if needed. Please dress for the weather, wear sturdy shoes, and bring your own personal water bottle and snacks. PP&R will provide litter grabbers and disposable gloves (you may also bring your own cloth gloves if you have them). 

Please register ahead of time hereand please complete this brief online health survey the day before the event: If you are not able to register online, please contact Yoko Silk directly. Due to COVID19 considerations, we are limiting group size and ask that all adults pre-register. 

Meet at: the last parking lot on Kelley Point Park road (also considered the main entrance). 

Questions: Contact Yoko Silk at or call/text 503-278-1341. 

Thank you for your interest in volunteering to keep Portland's natural area parks healthy, beautiful, and safe for people and wildlife!  
Here are a few tips to get you ready for your stewardship event. 

  • Registration is required for all stewardship events.   

  • Complete a health screening (brief online survey) the day before attending each event:   

  • Please volunteer close to home or in your community.   

  • Stay home if you are experiencing symptoms of any contagious illness or have had recent contact with someone exhibiting symptoms of any illness.   

  • Bring a face covering to be worn at the event and maintain at least 6 feet physical distance from others. PP&R will provide face coverings for anyone who doesn’t have their own.     

  • Volunteers are encouraged to bring their own gloves, water and snacks. If you have your own tools, feel free to bring those as well. PP&R will provide tools and gloves for anyone who does not have their own, and training for the days activity.  

  • In order to ensure your comfort and safety, please remember to dress for the weather, wear close-toed shoes, bring a water bottle, and be ready to get dirty!  

  • Unless otherwise noted, all events are family-friendly and all ages are welcome to participate. However, children must be accompanied and supervised by an adult for the duration of the event. We encourage you to attend events with members of your household/family!   

  • While groups are welcome to join many of our regularly scheduled stewardship events, please contact the event coordinator listed in the description before arriving with a large group. This will ensure that there are enough gloves and tools for everyone to work. We are also available to schedule special service events at your group's convenience during the week or on weekends. Learn more about programs for groups
