Lake Titicaca water level decline
Overview
Lake Titicaca is experiencing a significant reduction in water levels across the Andean region, affecting both Peru and Bolivia. In early October 2026, the National Service of Meteorology and Hydrology (Senamhi) in Peru reported a 53-centimeter drop since May, driven by rainfall deficits and high evaporation rates. Experts warned that levels could fall further if precipitation did not recover.
By late October, the decline had intensified. In Puno, Peru, the water level drop reached 62 centimeters, while the Huatajata station in Bolivia recorded a 59-centimeter decrease between April and October. Hydrologists noted that levels were 28 centimeters lower than the same period the previous year.
Long-term data indicates a 15-year downward trend in precipitation. While recent levels in some areas remain higher than in 2024, current measurements represent some of the lowest levels recorded since 1973. Experts anticipate reduced river flow feeding the lake starting in December, with projections suggesting below-average rainfall for early 2027.
