This article presents the results of a research made in order to determine the trophic status of the Laguna de La Cocha, an important body of water in Colombia and the world, which makes part of the RAMSAR Wetland Laguna de La Cocha, an ecosystem with different functions and the home of a big biodiversity that needs protection. To achieve this goal, this research was made between January and September 2013, determining the trophic status using the Carlson's index, the OECD's (Organization for Economic Cooperation and Development) index and the Carlson's index modified by Toledo. The results obtained made it possible to classify the Laguna de La Cocha as oligotrophic and ultraoligotrophic, typical characteristic of high-laying mountain lakes with low pollution processes of allochthonous and autochthonous origin.
