SYNDICAT DU BASSIN VERSANT DE L'YZERON

What SYNDICAT DU BASSIN VERSANT DE L'YZERON does

SAGYRC (Syndicat du Bassin Versant de l'Yzeron) is a French public intercommunal syndicate responsible for integrated water resource management across the Yzeron watershed in the Lyon metropolitan area. Its statutory mandate covers river maintenance, flood prevention, drought monitoring, wetland conservation, and environmental education for nine member municipalities. Core services include riparian restoration works (e.g., the 1.5 km, 28,000 m² renaturation in Oullins), operation of a 50-station drought observatory across 134 km of waterways, and mapping of more than 100 hectares of wetlands through a Stratégie Zones Humides program. The organization employs 9 staff under the presidency of Jean-Charles Kohlhaas, including technicians, engineers, and project managers.

The technology stack is built around ecological engineering (génie écologique), hydrological modeling via the IRIP software developed by INRAE, LIDAR-based topographic analysis, and the BYmap cartographic portal built on open-source Lizmap. The organization has institutional credibility demonstrated by selection for UNESCO's Ecohydrology demonstration site in 2015, the Prix National du Génie Écologique 2024, and the Prix Paysages en projet 2018. Notable partners include Métropole de Lyon, INRAE, SIAHVY, LPO, FRAPNA, the Conservatoire d'espaces naturels, CNR, and the local fishing federation, alongside an active volunteer Vigie network and school education programs.

SAGYRC is a public entity without commercial revenue; its operating budget is funded through statutory contributions from member communes, subsidies from the Agence de l'eau and Région Auvergne-Rhône-Alpes, and project-specific grants. Pricing and go-to-market mechanics are therefore administrative rather than commercial. In November 2025, the organization's territorial scope expanded with the installation of the Commission Locale de l'Eau (CLE) of the SAGE Garon-Yzeron, extending its regulatory mandate to the adjacent Garon watershed.

Core offering

SAGYRC provides integrated watershed management services for the Yzeron river basin, including water resource monitoring (with a 50-station drought observatory), river and stream maintenance (vegetation management, embankment stabilization, ecological restoration), flood prevention (infrastructure management, early warning, crisis simulation), wetland preservation and restoration, and environmental education programs for schools and communities. Digital tools include the BYmap cartographic portal and the Observatoire des sécheresses drought monitoring system.

Product overview

SAGYRC (Syndicat Intercommunal du Bassin de l'Yzeron) is a public intercommunal organization managing the Yzeron river basin. Rather than a single software product, it offers a portfolio of environmental management services including water resource management, river maintenance, flood prevention, and public education. Key digital offerings include BYmap, a cartographic portal for watershed data visualization, and an observatory system for monitoring drought conditions. The organization provides school animations and community outreach programs alongside technical river and wetland management services.
