Red Lake (Arizona–New Mexico)

Red Lake is a shallow, ephemeral lake located on the Arizona–New Mexico border, primarily within Apache County, Arizona, and extending slightly into Catron County, New Mexico. The lakebed is situated on the Defiance Plateau and is fed primarily by surface runoff from seasonal precipitation, including snowmelt. Due to the arid climate of the region, Red Lake is often dry or only partially filled.

Historically, the area surrounding Red Lake has been important for ranching and livestock grazing. The availability of water, even intermittently, has supported limited agricultural activities. The lake's name likely derives from the reddish hue of the sediments and soils in the surrounding area, particularly when water is present.

The ecosystem of Red Lake and its immediate vicinity is adapted to fluctuating water levels. Vegetation consists mainly of drought-resistant grasses and shrubs. Wildlife includes birds adapted to wetlands and playas, as well as mammals that utilize the area for forage and water.

The intermittent nature of Red Lake and its sensitivity to drought conditions make it a vulnerable ecosystem. Changes in precipitation patterns due to climate change pose a significant threat to its long-term viability. Land management practices in the surrounding watershed also influence the lake's water levels and overall health. While not a major tourist destination, Red Lake holds significance for local communities and the regional ecology.
