The Middle Rogue Pesticide Stewardship Partnership
In 2014, Jackson Soil & Water Conservation District and other local partners joined 8 other sites in Oregon to monitor pesticide levels in local surface waters as part of the Pesticide Stewardship Partnership (PSP) Program. This program works to help residents of Oregon understand and reduce the levels of agricultural, commercial, and residential pesticides reaching our state's waterways. The map to the right shows all 9 PSP basins in the state.
Why?
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.
Where?
The Middle Rogue Pesticide Stewardship Partnership is the southernmost PSP location in the state of Oregon.
2020 - 2022 sampling locations through October 2022:
- Jackson Creek at Bransom Lane
- Wagner Creek at Bear Creek Confluence
- Payne Creek at Fern Valley, west of Marigold
- Lone Pine south of Veranda Park
- Lone Pine near Lawnsdale Road
2019 sampling occurred at the following locations:
- Jackson Creek at Bramson Road
- Larson Creek at N. Phoenix Road
- Larson Creek at Ellendale Drive
- Payne Creek at Fern Valley Road
- Wagner Creek at Bear Creek Confluence
What does this mean for you?
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 additional information on when and where to use a chemical, its environmental persistence, and potential environmental impacts of a chemical.
