Abstract: This study analyses long-term hydrological data (1979–2024) to assess the management of a hydrosystem where a conflict between hydropower production and irrigation activity appears. Trend analysis suggests a tendency for lower inflows to the reservoirs during April–June and a slight tendency for higher inflows in January–March, likely related to shifts in the snowmelt period. However, these inflow tendencies alone do not justify the recent significant reduction in water allocated for irrigation, which appears primarily driven by operational management prioritizing energy production. The findings highlight the need for comprehensive multicriteria operational strategies to balance hydropower profitability with water availability for agriculture.
