The Clackamas Basin Pesticide Stewardship Partnership
The Clackamas River provides drinking water for 300,000 people, recreation for thousands, and safe harbor for endangered fish to spawn, rear and migrate. The Clackamas Basin Pesticide Stewardship Partnership (Clackamas PSP) is a voluntary, collaborative process to protect the river and its tributaries. Local and state organizations offer water quality monitoring, resources and training for landowners and managers to enable more efficient and effective pesticide use that reduces drift and runoff.
Helping Clackamas Growers and Applicators “Keep it Local!”
THE PROBLEM: Pesticides carried by stormwater runoff, wind, and irrigation can contiminate steams and the Clackamsas River, threatening aquatic life and the safety of drinking water. Regulations will be put in place unless we solve the problem locally.
THE SOLUTION: We need your advice and expertise. Help us understand how pesticides are applied to gardens, lawns, crops, and nursery stock. Work with the Clackamas River Basin Council, Clackamas Soil and Water Conservation District, and Oregon State University to create a plan for the Clackamas Watershed.
YOUR PARTICIPATION: By joining in this collaborative effort, our region can avoid costly regulations and time consuming reporting for businesses. You will learn about improved application practices that are effective and save money, and get technical assistance for implementation and equipment upgrades. Local efforts will generate good neighbor relations, a Clackamas River Basin that is healthy for aquatic species, and a safe drinking water sources.
GET INVOLVED EARLY!: Make your priorities know. A local council of growers, applicators, crop consultants, and pesticide dealers will create a strategic plan to avoid costly and time consuming regulations. Be part of the solution!

Pesticides of Concern
Since 2000, water monitoring has detected pesticides in Clackamas River tributaries that exceed benchmarks to protect fish and invertebrates. Since 2005, Oregon Department of Environmental Quality has monitored four sites on tributaries to the lower Clackamas River for pesticides:
- Noyer Creek
- North Fork Deep Creek (two locations)
- Rock Creek
- Sieben Creek
Pesticide active ingredients and common trade names of pesticides found in the Clackamas Basin at high levels or frequencies of concern include:
- simazine: Princep
- chlorpyrifos: Yuma and Lorsban Advanced
- bifenthrin: Capture 2EC, Brigade 2EC, Brigade WSB, Wisdom
- diuron: Karmex, Direx
- oxyfluorfen: Goal 2XL, Goal Tender
- chlorothaloni: Bravo Weather Stik, Chloronil 720
- dichlobenil: Casoron
Voluntary Steps in a PSP
- Monitor water quality to identify pesticides of concern (approaching or above unsafe levels, or found at high frequencies).
- Share and explain water quality monitoring results with those who are interested in protecting the quality of local streams and rivers.
- Engage pesticide users and technical assistance providers to identify and implement voluntary solutions to reduce pesticide drift, runoff, and waste.
- Use long-term water quality monitoring to measure success in reducing pesticides of concern and evaluate the effectiveness of strategies.
Why Pesticide Stewardship Partnerships?
Healthy drinking water. Clean rivers. Native salmon. Abundant wildlife. Safe fish to eat.
More efficient operations. Money saved through waste reduction. Reduced risk of regulation, environmental clean-ups, and negative health effects. Community-based knowledge, not “one-size-fits-all” fixes.
For best practice pest management
Integrated pest management principles ensure efficient, appropriate use of pesticides. Preventing pests, using pesticides only when necessary, and using the least pest control chemicals to be effective help prevent off-target movement of pesticides where they are not useful and can be harmful.
An Oregon-Grown Win-Win Strategy
Oregon’s Pesticide Stewardship Partnerships (PSPs) began in the Hood River basin and have expanded to seven watersheds in the Willamette and Columbia River Basins.
Partners have included local landowners, grower groups, watershed councils, soil and water conservation districts, water provides, Department of Environmental Quality, Oregon Department of Agriculture, Oregon State University, tribes, Oregon Environmental Council, and several other nonprofit organizations.
Providing technical resources and water testing to local experts, these partnerships have resulted in locally led initiatives that improve pest management efficiency and create measurable environmental improvements.
