The near-total depletion of the San Carlos Reservoir has significant ecological, economic, and public health implications. The hypoxic conditions have killed nearly all fish in the reservoir, disrupting local ecosystems and recreational fishing activities. The San Carlos Recreation and Wildlife Department has warned of potential health risks from decomposing fish, which could affect those attempting to fish or boat in the area. Historically, the reservoir has experienced similar low-water events, but the current situation underscores the increasing vulnerability of water resources in the Southwest due to prolonged drought and climate variability.
