Presa la Boca, Dam in Santiago, Mexico

Presa la Boca is a large dam and reservoir surrounded by mountain terrain and natural landscape in Nuevo León. The water body offers space for boating, fishing, and water sports throughout the year.

Built in the early 1960s as the Rodrigo Gómez Dam, it was designed to supply water to Monterrey and its metropolitan area. On 29 March 2022, during the Nuevo León drought, the state government stopped drawing water from it for the city. By 10 July 2022 it held only 7% of its capacity; rains from Hurricane Kay raised it to 61% by the morning of 6 September 2022.

The reservoir is named after Rodrigo Gómez, a former director of the Banco de México. Its water level is closely watched by residents of Monterrey, and the dramatic drop to 7% capacity in July 2022 became a reference point in local conversations about drought.

The location is accessible by road and has launching areas for boats and equipment rental at several spots. Plan your visit around weather conditions, as water activities depend on wind and water level throughout the year.

The reservoir's level swings sharply: it fell to 7% of capacity by 10 July 2022 during the Nuevo León drought, then rose to 61% on the morning of 6 September 2022 after rains from Hurricane Kay. The state government had stopped drawing water from it for metropolitan Monterrey on 29 March 2022.
