The South Fork Trinity watershed covers an area of approximately 1,144 square miles in Northern California. It is a major source of water for the Trinity River, and is characterized by a Mediterranean climate with hot, dry summers and wet winters. The watershed receives significant amounts of precipitation in the form of snow during the winter months, which contributes to the snowpack that feeds the rivers and reservoirs during the dry season. The reservoirs in the watershed are important for water storage and hydroelectric power generation. The area has experienced droughts in recent years, which have impacted water availability and ecosystem health. In addition, the watershed is home to a diverse range of plant and animal species, including several threatened and endangered species such as the northern spotted owl and Chinook salmon.
