Great Lakes Restoration Initiative: Upper East River in-stream phosphorus dynamics data during runoff events in 2022 and 2023

Nutrient and soil runoff from agricultural fields in the Upper East River basin contribute to eutrophication in downstream waters like Lake Michigan. Phosphorus is often the limiting nutrient in freshwater ecosystems and the binding of dissolved phosphorus to suspended sediment can reduce its bioavailability. These data provide information about what size particles are binding phosphorus and how the proportion of total phosphorus that is dissolved changes as the phosphorus is transported from the field through the stream network during runoff events. Samples were collected for analysis in 2022 and 2023. Information about management of Wisconsin Waterway 3 was also collected from 2020-2023 and is included in this data release.
