The Middle Rogue Pesticide Stewardship Partnership

In 2014, Jackson Soil & Water Conservation District joined 8 other sites in Oregon to monitor pesticide levels in local surface waters. This program is called the Pesticide Stewardship Partnership, and calls for all residents of Oregon to work to understand and reduce the levels of agricultural, commercial, and residential pesticides reaching our state's waterways.


A pesticide, as defined by the Environmental Protection Agency, is any substance, or mixture of substances, intended to prevent, destroy, repel, or mitigate any pest. A pest, while most commonly thought of as an insect, may include fungi, bacteria, rodents, and plants. A pesticide may be used on any of these common pests and may be labeled as fungicides, rodenticides, insecticides, or herbicides.

While all legally available pesticides have undergone strict regulatory testing for efficacy and safety, it is important to do as much as possible to reduce non-target application and distribution of these chemicals to preserve soil, air, and water quality. In the state of Oregon, our waterways provide municipal drinking water and agricultural irrigation; are integral habitat to salmon, Pacific lamprey, & steelhead; are economically important recreation centers; and are aesthetic corridors for residents and visitors alike. By partnering with state and local agencies to monitor pesticide levels, we can better develop a plan of action to make sure these waters stay clean and healthy for years to come.

The Middle Rogue Pesticide Stewardship Partnership is the southernmost PSP location in the state of Oregon. 

2018 sampling will occur at the following locations:

  1. Jackson Creek at Bramson
  2. Wagner Creek at Wagner Creek Trail
  3. Wagner Creek at Mouth (Truck Stop)
  4. Payne Creek at Fern Valley
  5. Larson Creek N Phoenix
  6. Larson Creek Ellendale

What does this mean for you?

JSWCD's Natural Resource Technician, Jenna Sanford, collects a water sample from Wagner Creek at the Wagner Creek Interpretive Trail trailhead.

Whether you use pesticides to control your backyard weeds or to prevent devestating crop loss, it is important to understand how the chemicals you use interact with the environment. Some chemicals readily break down into less hazardous compounds, while others may persist for years. Our sampling and subsequent testing and analysis by Oregon's Department of Environmental Quality help us to develop a picture of when and where certain chemicals are entering a waterway. The data we collect includes flow, weather, date, and watershed location. All of these factors are important indicators as to why a certain chemical may be detected at a specific time. Did we just see a big rain event after chemical application? Was the water level especially low, thereby increasing concentrations of a chemical on a given day? Which chemicals are applied to which crop?

As our data set grows, we will develop outreach and communication plans for specific user groups of detected chemicals which will include additinal information on when and where to use a chemical, its environmental persistence, and potential environmental impacts of a chemical.
