A major concern of mining activities is their influence on hydrological systems. This article highlights impacts on water flows and distribution in the Mashcon catchment in Cajamarca, Peru, one of those most affected by the Yanacocha mining project. Some important concerns are identified regarding changes in water flows, lowering of water tables, and decrease of base flows. These considerations indicate deficiencies in distributing actual water uses in relation to the allocation of water rights. Finally, the article discusses challenges for regulation of mining, including democratic processes for water management that require clear accountability in the context of local social needs.
