Hydro-Quebec and Cemagref have implemented condition evaluation methods for water retaining structures: the condition index (CI) method for embankment dams in Quebec, and SIRS Digue for fluvial dykes in France. These methods were developed from similar approaches, including functional analysis, gathering and formalization of knowledge about failure mechanisms, and definition of performance indicators. Development of both methods was done within a group of experts and lead to technical guides that explain the application limits. The main objective is to prioritize maintenance tasks within a large inventory of dams for Hydro-Quebec, and for fluvial dykes, in France. The use of these methods reaches also other goals at the same time: aid to safety review and dam diagnosis, and experience transfer among the technical staff. RESUME. Hydro-Quebec et le Cemagref ont mis en œuvre des methodes d'evaluation de l'etat des ouvrages : respectivement la methode des indices de condition (IC) pour les barrages en remblai au Quebec et le SIRS Digue pour les digues fluviales en France. Ces methodes ont ete developpees a partir d'approches methodologiques analogues, l'analyse fonctionnelle, le recueil et la formalisation de la connaissance sur les mecanismes de rupture des ouvrages et la definition d'indicateurs de performance. Leur developpement a ete realise au sein d'un groupe d'experts et a conduit a la redaction de guides techniques constituant les regles d'application. L'objectif prioritaire recherche est la programmation des actions de maintenance au sein du parc de barrages d'Hydro-Quebec et du parc de digues en France. L'utilisation de ces methodes permet d'atteindre egalement des resultats sous-jacents : l'aide a la revue de securite et au diagnostic des ouvrages et la capitalisation de la connaissance au sein des organismes.
