Laguna Coronda is a large freshwater lake located near Arocena, roughly midway between Rosario and the city of Santa Fe in Santa Fe Province, Argentina. The water body spans more than 15 kilometers in diameter, making it a substantial open-water paddling environment. Its name derives from the cacique Coronda, who was regarded as a great lord at the time of the Spanish arrival.

The laguna is accessible only by water — there is no land-based access to many of its features — so paddlers should plan accordingly. Local guides operate in the area, and at least one guiding service (Agustina La Pescadora, based near the laguna) offers navigation assistance for those unfamiliar with the waterway.

One of the more unusual features of Laguna Coronda is a series of waterfalls or cascades that form where the laguna drains into Arroyo Cabrera. These are only visible during periods of low water; when river levels rise, the cascades are submerged and cannot be seen. During significant low-water events, the exposed lakebed reveals remnants of sunken boats and a layer of freshwater shells and snails.

The laguna functions as an important natural nursery for fish species of the region, with conditions of water temperature and bottom substrate that support spawning and reproduction. Species such as dorado are present. Birdlife in the surrounding wetlands includes Lechuza Vizcachera and Garza Blanca, among others.

Water levels fluctuate considerably with the seasonal behavior of the connected river system, which directly affects what features are accessible or visible. Paddlers should be aware that the open expanse of over 15 km can expose them to wind and fetch, and that navigating to specific points of interest such as the cascades requires local knowledge or a guide.
