The primary goal was to re-evaluate the effectiveness of phosphorus retention due to Duncan Dam operations, as part of a broader assessment of dam impacts on nutrient retention within the reservoir. This study updates the previous 1994-1995 analysis to guide future management and funding contributions to the KLNRP.
The study found that phosphorus retention in the reservoir remains significant, with notable retention of both particulate and dissolved forms. A small increase (0.8%) in TDP retention was observed compared to the 1994-1995 period. Results emphasized the impacts of climatic changes, wildfire disturbances, and operational adjustments on phosphorus dynamics, supporting the ongoing relevance of BC Hydro's financial contributions to nutrient restoration.
