The Strait of Georgia watershed covers 22,500 square kilometers and spans southwestern British Columbia, Canada. The hydrology of the watershed is complex due to the interaction of coastal, mountainous, and lowland ecosystems. The snowpack in the mountains is an important source of surface water for the region, with significant snow accumulations in the winter months. Surface water quality is affected by human activities, such as agriculture and urban development, which introduce nutrients and pollutants. Reservoir constituents include fish, such as salmon and trout, and other aquatic organisms. Interesting climatic facts include a warming trend in the region, which has led to reduced snowpack and increased wildfires in recent years. Additionally, the watershed is vulnerable to sea level rise, which could have significant impacts on the region's hydrology and ecology.
