Background on Key Figures and Relevance

Nuevo León, Mexico is experiencing heavy rainfall that has increased the flow of River Santa Catarina. The situation has prompted actions from local authorities, including Governor Samuel García and Luis Carlos Alatorre Cejudo, the General Director of the Rio Bravo Water Resources Commission (Conagua).

Governor Samuel García is the current leader of Nuevo León, elected in 2019. His administration focuses on managing natural resources and ensuring the well-being of the region’s residents. Luis Carlos Alatorre Cejudo, as the head of Conagua’s Rio Bravo Water Resources Commission, plays a crucial role in monitoring water resources and coordinating responses to extreme weather events.

Current Situation and Actions Taken

On Monday, September 8, intense rainfall in Monterrey and the Sierra Madre Oriental caused River Santa Catarina’s flow to rise significantly. In response, Governor Samuel García and Conagua’s Luis Carlos Alatorre Cejudo took the following actions:

  • Controlled Discharge at La Boca: Due to the reservoir exceeding 100% capacity, Conagua initiated a controlled discharge of 50 cubic meters per second from La Boca.
  • Monitoring Presa El Cuchillo: Authorities are observing the rise in Presa El Cuchillo’s water level, anticipating further increases due to ongoing and forecasted rainfall.
  • Maintaining Presa La Boca at 95% Capacity: García Sepúlveda ensured that Presa La Boca remains above 95% capacity, balancing water intake from heavy rains and controlled discharge.
