Nutrients and Discharge in the Brush Creek Watershed in Northwest Arkansas

This dataset supports the Quantifying Ecosystem Losses across Dimensions of Space and Time (QuEST) project investigating nutrient dynamics under baseflow conditions in an agricultural non-perennial stream in a rural heterogenous landscape dominated by pasture/hay and forest area in Northwest Arkansas. This data includes monthly spatially intensive baseflow sampling of 20 sites nested across Brush Creek from October 2023-September 2024 for nitrate (NO3-N), soluble reactive phosphorus (SRP), discharge (Q), and flow state (F=flowing, P=pooled, D=dry). The interactive effects of agricultural land use and stream intermittency are understudied and thus makes our findings important in developing targeted management approaches as flow variability increases.
