The Knife Watershed, located in northern Colorado, covers an area of approximately 175 square miles. The watershed is characterized by steep slopes, high peaks, and deep valleys, which contribute to its unique hydrology. The region experiences a semi-arid climate with hot summers and cold winters, resulting in low annual precipitation and specific snowpack. The watershed is home to several surface water sources and reservoirs, including the Horsetooth Reservoir, which plays a significant role in the region's water supply. The reservoir receives water from the Cache La Poudre River, which originates in the Rocky Mountains and flows through the watershed. In recent years, the region has experienced changing climate patterns, including increased temperatures and decreased snowpack. These changes have had a significant impact on the region's water supply, with many of the reservoirs facing low levels due to decreased snowmelt. Overall, the Knife Watershed plays a significant role in the region's hydrology and water supply, and its changing climate patterns pose a significant challenge to the region's water management.
