Surface Flow Characteristics


Wyoming has a semi-arid climate with an average annual precipitation of 14 inches. The state contains major surface flows such as the Green River, North Platte River, and the Snake River. The Wind River Range contains the headwaters of the Green and Snake Rivers. The state has many reservoirs and dams that are used for irrigation, flood control, and hydroelectric power generation. Snowpack in the mountains is a critical source of water for Wyoming's rivers, and snowmelt runoff typically peaks in May and June. The state is also affected by drought conditions, which can lead to reduced water availability and increased wildfire risk. Overall, Wyoming's hydrology is influenced by its specific geography, climate, and water management practices.
