The Middle South Platte Cherry Creek watershed, located in Colorado, covers approximately 2,290 square miles. The hydrology of the area is dominated by the South Platte River and its tributaries, including Cherry Creek. The region experiences a semi-arid climate with an average annual precipitation of 15 inches, primarily in the form of snow during the winter months. Snowpack is an important component of the area's water supply, with up to 80% of the annual precipitation occurring between November and April. The largest reservoir in the watershed is Chatfield Reservoir, which holds up to 27,000 acre-feet of water. The region is susceptible to droughts, with the most severe drought occurring in the early 2000s. Climate change is expected to increase the frequency and severity of droughts in the region, which could have significant impacts on water resources and agricultural production.
