General Description

The Maule River is located in the Maule Region, Region X of Chile. In the Mapuche language, the mother tongue of the pre-Columbian Amerindians it means “river of fogs”. The Maule River was the southern most river in the Incan empire and demarkated it’s southern border. The Maule River is born from the waters of Laguna del Maule in the Talca Province, at an altitude of about 7100 feet (2150 meters) near the border of Argentina. Over a course of 150 miles (240 km) from headwaters to the Pacific the Maule River is joined by an extensive number of tributaries including the Rio Melado, Rio Ancoa and Rio Achibueno. The Maule River also lends its name to one of the greatest wine making regions in Chile, “The Maule River Valley”.

Unfortunately, in the modern era, the Maule River leaves a much uglier legacy. Currently the Rio Maule is one of Chile's most “plumbed” rivers due to exploitation by the hydropower industry. Significant portions of the Rio Maule are dewatered with all of the flow traveling through underground tunnels to power electricity generating turbines. It is a rare kayak run down the Rio Maule that won’t encounter these dewatered sections. Because the environmental protection of rivers in Chile is still in its infancy there are no scheduled releases for recreational boaters on these sections. If you want to kayak the Maule River you will have to take your chances.

Except for up top, and a few diversion dams and waterfalls below, the Maule River can best be characterized as a class IV/IV+ river of continuous noise.

Hazards

Before the river was developed for hydropower, Chris Spelius ran the entire river from Laguna del Maule to the ocean, portaging around waterfalls and other hazards whenever necessary. Most of the natural hazards occur above La Mina Fortuna. Plan on portaging these. Below La Mina Fortuna there is mostly class IV/IV+ continous action. However, as you get closer to Lago Colbun be on the look-out for one huge waterfall (80+ meters) that you will need to portage. Because the Maule River is so plumbed for hydropower, be on the lookout for man made hazards like diversion dams, etc.

River Flows / Gauge Information / Season

There are two reporting stations on the Rio Maule River that will help in determining flows on the runnable sections. One of these lies at the top of the Rio Maule at Laguna del Maule. The other lies at the bottom, in the small village of Armerillo just before Lago Colbun. These two stations will provide you with minimum / maximum flow rates.

Directions

From the city of Talca and the Pan American Highway (Ruta 5) take the International Highway (Ruta CH115) to the city of San Clemente. Continue East on Ruta CH115 past Lago Colbun to the La Mina Fortuna outpost, following the Rio Maule all along the way. The total distance is about 65 miles (105 km)over paved and unpaved roads.

Places to Stay / Campgrounds

The Lago Colbun region is a great aquatics recreation area with numerous places to camp or cabins to rent.
