Dataset: Daily Flows and Nutrients Loads in the Sprague River Basin, WY2002-2020

Daily flows and nutrient (phosphorus, nitrogen, total suspended solids) loads were estimated for multiple locations in the Sprague River Basin (OR) over water year (WY) 2002-2020. These timeseries were computed using continuous and biweekly flow data in combination with biweekly nutrient measurements collect by Klamath Tribes at eight sampling stations across the basin. The estimated timeseries were then used as a basis to investigate the spatial and temporal dynamics of nutrient concentrations and loads, estimate relative amounts of background and anthropogenic loading, assess the potential impacts of the Klamath Tribes' water rights calls on instream flow and water quality in recent years, and evaluate long-term trends at each sampling station within the Sprague River basin.

The data sources and methodologies used to generate this dataset are described in the following report:
