The most important rivers in Jalisco are the Lerma, the San Juan de los Lagos river and the San Miguel river, among others. It is a state with abundant water resources, since it concentrates 15% of the total of the country.
Due to this, there are numerous dams scattered throughout the region, as well as a large number of lakes that receive water from the rivers.
Jalisco in a state belonging to the United Mexican States. Its capital is Guadalajara and it is located in the western region of the country, bordering the Pacific Ocean.

The 3 hydrographic groups of Jalisco
In general lines, the rivers of Jalisco are divided into three large groups, with the common characteristic that they all go towards the Pacific Ocean.
1- Lerma River - Santiago
It is the most important in terms of water resources in the entire State. The main river that belongs to this region is the Lerma, the longest of the country's interior rivers.
It is born in the state of Mexico and flows into Lake Chapala after traveling 750 kilometers.
Lake Chapala is the source of the other great river in this hydrographic region, the Grande Santiago. Its influence is very great: three-quarters of the population is grouped around its waters.
Other rivers in this group are the Verde River, the Huaynamota River, and the Bolaños River.
2- Rivers that flow into the Pacific
This hydric region is characterized by its shorter rivers, because the mountains where they are born are near their mouth in the Pacific.
Among the rivers that flow into the ocean, the most important is the Ameca, which is born on the Colli hill. It is located on the border with the state of Nayarit and is 230 kilometers long.
Also there is the Cihuatlán river, serving as the border with Colima. This forms the bay of Barra de Navidad at its mouth.
More rivers in this area are the Mascota, the Tomatlán and the Purificación.
3- Rivers of the south of the State
The most important river current in this region is the Armory. This has its birthplace in the Sierra de Quila, in the center of Jalisco.
It receives several names during its 240 kilometers of travel. In its origin it is known as the Atengo River, later as the Ayutla River, and just before leaving Jalisco it is called the Ayuquila River. It empties into the state of Colima, it is the waters of the Pacific.
Other rivers in this region are the Tuxpan and the Tuito.
Environmental problems in the rivers of Jalisco
The river wealth of the state of Jalisco faces a short-term problem that can cause the disappearance of many natural resources.
According to the University of Guadalajara, up to 85% of the water has alarming and dangerous industrial pollution levels for the population.
This study concludes that the most affected is the Santiago River, which, due to its connection with Lake Chapala and the Lerma River, spreads contamination by many other aquifers, causing serious diseases to humans and animals.
