The reservoir's water level is subject to significant fluctuations based on seasonal irrigation demand and rainfall patterns.
Embalse de Arenós is a major reservoir situated on the Mijares River, serving as a critical infrastructure project for water management in the Valencian Community. It is formed by a concrete gravity dam located within the mountainous region of the Alto Mijares. The reservoir functions primarily for irrigation supply, hydroelectric power generation, and flood control for downstream municipalities. Its vast, tranquil waters are surrounded by rugged limestone terrain characteristic of the Iberian System. The site is a focal point for water-based recreational activities, including kayaking, paddleboarding, and swimming, especially in areas adjacent to the town of Montanejos. The reservoir basin encompasses parts of the municipalities of Puebla de Arenoso and Montanejos. It is fed primarily by the Mijares River, which flows through the narrow canyons typical of the province of Castellón.
