Lake Sumner is a reservoir located in the eastern part of New Mexico, United States. The lake was formed in the 1930s by the construction of a dam on the Pecos River. It is primarily fed by the Pecos River and its tributaries, as well as by snowmelt from the nearby mountains. The lake serves as a source of irrigation water for agricultural purposes and is also used for recreational activities such as fishing, boating, and camping. The surrounding area is home to several species of wildlife, including deer, elk, and pronghorn antelope. In recent years, the lake has faced challenges from drought and overuse, leading to concerns about its long-term sustainability. Efforts are underway to address these issues through improved water management and conservation measures.
