Mexican reservoir fluctuations and Guadalajara water quality crises crisis

Heavy rainfall in Mexico continues to cause significant fluctuations in reservoir capacities and necessitates active water management. In Guanajuato, the Mata and La Esperanza dams are nearing 100% capacity, while the La Soledad dam has recovered to 36% capacity. Juan Andrés Balderas, director of SIMAPAG, stated that these levels guarantee the municipal water supply for the remainder of the year. Authorities are currently rehabilitating water intake works at the La Soledad and La Esperanza dams. In Zacatecas, the Leobardo Reynoso dam remains at 43% capacity; SADER officials indicate this volume is sufficient for the upcoming agricultural cycle, though a midsummer drought may impact seasonal crop yields in northern Fresnillo. In Hidalgo, the National Water Commission (Conagua) is conducting a controlled release from the Endhó Dam, which reached 102.4% capacity. In Querétaro, authorities have initiated controlled discharges from several dams, including the El Carmen dam, which reached 100% capacity. The Guadalajara metropolitan area is managing a water quality crisis. To address contamination, the government has begun dredging the Las Pintas and La Calera dams to reduce pollutants and recover storage capacity. dams. Following reports of dirty, malodorous water caused by irregular discharges in the Las Pintas canal and aging infrastructure in the Chapala-Guadalajara system, water, Jalisco Governor Pablo Lemus Navarro has implemented a six-month water rotation scheme. This SIAPA clarified that this measure results in reduced availability and scheduled service interruptions. Long-term mitigation strategies include modernizing the Miravalle Water Treatment Plant, completing the La Calera diversion aqueduct, and proposing a new Chapala-Guadalajara aqueduct. To improve communication, SIAPA has launched ‘SIAPA Bot’, a WhatsApp-based digital tool allowing residents low water pressure across approximately 627 neighborhoods in Guadalajara, Zapopan, and San Pedro Tlaquepaque, rather than total service cuts. To manage recovery, affected areas are divided into seven operational zones with alternating pressure levels. SIAPA Director General Ismael Jáuregui Castañeda recently adjusted these rationing schedules to improve distribution and Tonalá precise recovery times. To assist residents, SIAPA launched ‘SIAPA Bot’ on WhatsApp to report supply shortages and water quality issues. Additionally, a digital mapping project titled ‘Del lago a la llave’ has emerged to track supply issues and Santiago River contamination.
