CCR Nutrient Loading
Cherry Creek contributes the majority of phosphorus and nitrogen loading to the Reservoir due to its relatively high flow. Cottonwood Creek is responsible for over 25% of the nitrogen loading although it contributes only 18% of the flow to the Reservoir.
Phosphorus and nitrogen loading to the Reservoir results from surface water from Cherry and Cottonwood Creeks, precipitation and alluvial groundwater. The water quality from the monitoring sites closest to the Reservoir are used for the calculations for each of the inflow sources.
