The Necaxa River (Río Necaxa) is one of the main rivers of the Mexican state of Puebla. It is a tributary of the Tecolutla River. Beginning south of Huauchinango with the name Totolapa, it runs through tall mountains and deep canyons of the Sierra Madre Oriental, forming the waterfalls known as Salto Chico y Salto Grande. Its flow is also used to generate hydroelectric power.

Geography

The Necaxa River rises along the boundary of Hidalgo and Puebla states, and flows eastwards through the Sierra Madre Oriental of Puebla and Veracruz. It joins the Apulco River in Espinal, Veracruz to form the Tecolutla River, which empties into the Gulf of Mexico.

Together with four other rivers, the El Tejocotal, Los Reyes, Patla, and Tenango, the Necaxa produces a total of 172 million litres of water generating electrical power not only for Puebla, but for the states of Tlaxcala, Hidalgo, Mexico, and the Federal District, in addition to many people in the center of the country.

Five dams were built in the Necaxa River basin for water storage and producing hydroelectricity.

Small-scale forestry takes place in the watershed.

Flora and fauna

The river basin's reservoirs are habitat for waterfowl, including the great egret (Ardea alba), snowy egret (Egretta thula), little blue heron (Egretta caerulea), neotropic cormorant (Phalacrocorax olivaceus), ringed kingfisher (Megaceryle torquata), and green kingfisher (Chloroceryle americana). Endangered species found in the river and its basin include the Puebla frog (Lithobates pueblae) and the tree fern Cyathea mexicana.

On 20 October 1938, President Lázaro Cárdenas decreed the Necaxa River basin in Hidalgo and Puebla a protected forest zone (zona protectora forestal) in order to preserve the basin's forests and climate, prevent soil erosion, and stabilize the rivers' flow for production of hydroelectricity. The protected forest zone covers an area of 421.29 km2 in the municipalities of Acaxochitlán, Cuautepec de Hinojosa, Naupan, Huauchinango, Juan Galindo, Xochiltepec, Zihuateutla, Tlaola, Chiconcuautla, Jolalpan, Zacatlán, and Ahuazotepec.

On 9 September 2002 the Mexican government re-designated the basin a natural resources protection area.

The five reservoirs in the basin were designated a Ramsar site (wetland of international importance) on 2 February 2008. The Ramsar site covers a total of 1,541.4 ha.

Navigability

This river is adapted for navigation as the generating plant opens its floodgates to the full flow of the river to permit boats to pass against the current.

The Necaxa is a Class III River.

Access

From Mexico City, take the Mexico-Tuxpan road and drive to Tulancingo. Then drive to Huauchinango with final destination to "El Salto" (the location of a CFE's hydroelectric plant).
