There are currently 1,230 dams in Spain (987 of which being large dams, according to ICOLD criteria), with an average age of nigh on 50 years and where the main problem is subsequently one of maintenance and conservation. In addition to which, there are a further 100,000 irrigation reservoirs, located mainly on the Mediterranean coast and in the main irrigable areas of the Ebro and Guadalquivir. In view of the importance of these dams and reservoirs in the high level of development achieved in Spain over the latter half of the 20th century, the article examines the influence of maintenance and conservation action with respect to the safety and operation of this specific infrastructure, with particular attention to the work earned on those dams that come under the auspices of the Spanish Ministry of Agriculture, Food and Environmental Affairs (MAGRAMA). The article reviews the work required for the maintenance and conservation of a dam or group of dams and examines how the development and planning of this work has evolved over time (from initially purely routine work). The author goes on to describe the technological advances that have favoured the use of basic tools to help ensure the correct safety management of dams, as is the case of the Risk Analysis method currently employed worldwide. This modern method of dam and reservoir safety management makes it possible to prioritize the investment necessary to guarantee safety and the good state of the installations, while allowing the efficient and effective management of dam information to be passed on to the owners, these both being key aspects for the correct planning of all dam maintenance.

This paper summarizes the design philosophies, construction methodologies and essential characteristics of the 28 RCC Spanish dams that are currently in operation (27) and under construction (1). The authors describe their cross sections, their main structural aspects and the basic characteristics of the mixtures used in their construction.
