Contribution of phosphorus from dustfall and precipitation to Okanagan lakes was first evaluated during the Okanagan Basin Study. Results of this study indicated that phosphorus from the atmopshere could form a significant portion of the nutrient load to shallow lakes such as Wood, south basin of Osoyoos and headwater lakes. A review and update during the Okanagan Basin Implementation Study noted spatial and temporal variability in airborne phosphorus durin a short study and contamination of collectors which reduced loading estimate accuracy.
