Summary

This data release includes physical and chemical data for samples from upland-source and streambank sampling sites in the Black Creek basin, Indiana. Data include total nitrogen and carbon concentrations, carbon species, total concentrations for 42 metals, and particle-size analysis. Source samples were identified as one of five land-use types: active cropland (corn, soybean, hay, and wheat), active horse pasture, roads, preserved forest, and streambanks of agricultural and non-agricultural channels. Source data were collected in August and September 2017. These data are used for source attribution in order to quantify the proportional contribution of individual sources to suspended sediment and streambed collected in 2018 [Williamson [...]

Purpose

The study was designed to identify the proportional contribution of different land-use types to suspended sediment and soft, streambed sediment and to characterize how sediment source of suspended sediment varied during the year. A second phase of the study characterized stream reaches in order to quantify streambank erosion and storage of soft-streambed sediment. This information will enable resource managers to improve how different land uses are managed in order to decrease delivery of sediment and the nutrients that travel with this sediment to streams. Ultimately, a decrease in sediment and nutrient concentrations in the stream will decrease what is delivered to the Maumee River and western Lake Erie, preventing the conditions that lead to harmful algal blooms.
