The Tumarín Dam is a gravity dam currently under construction on the Río Grande de Matagalpa just upstream of the town of Tumarín in the South Caribbean Coast Autonomous Region, Nicaragua. It is located about east of San Pedro del Norte, where the Río Grande de Matagalpa meets the Tuma River. Preliminary construction (roads, bridges and foundation) began in 2011 and main works are expected to begin in February 2015. Completion is scheduled for 2019. Brazil's Eletrobras will fund the US$1.1 billion under a 20 to 30 year build–operate–transfer (BOT) agreement. The project is being developed by Centrales Hidroelectricas de Nicaragua (CHN). The power station located at the base of the dam will house three 84.33 MW Kaplan turbine-generators for an installed capacity of 253 MW.
