Short summary
Long-term catchment sediment and nutrient budgets are important for managing soil and nutrient resources for more sustainability. Here we construct a 14-year budget of water, sediment and nutrients across two subtropical reservoirs. A major flood in January 2011 dominated flow and loads in and out of both reservoirs. Sediment and nutrient budgets are inherently dynamic, and our results demonstrate that meaningful reservoir budgets require reliable estimates of uncertainty and variability.
