Impact of the old dam upon the water quality at the intake in San Roque Reservoir (Cordoba, Argentina)

The San Roque reservoir (Córdoba, Argentina) is the main resource for drinking water to the city of Córdoba and its surroundings with a total population of nearly 1,500,000 inhabitants. A characteristic of this reservoir is the presence of an old wall (built in 1888) acting as a submerged weir upstr...
