John Martin Reservoir is a man-made lake in southeastern Colorado, created in the 1940s as part of the Arkansas River Basin Project. It is fed primarily by the Arkansas River, as well as by other smaller streams and irrigation canals. The reservoir serves as a vital source of water for irrigation in the surrounding agricultural area, and also provides opportunities for fishing, boating, and camping. In recent years, the reservoir has faced challenges due to drought conditions and reduced snowpack in the surrounding mountains, leading to lower water levels and concerns about water availability for agriculture and other uses. Despite these challenges, John Martin Reservoir remains an important resource for both the local community and visitors to the region.
