Rivers of Spain: 1,200+ Waterways, Five Giants

Spain's Hydrological Wealth

Spain has over 1,200 rivers, but five dominate by length and basin:

1. Tagus (Tajo): 1,007 km (longest in Iberia). Madrid, Toledo, Lisbon (Portugal).
2. Ebro: 910 km (longest wholly in Spain). Zaragoza, Delta del Ebro (wetland).
3. Guadalquivir: 657 km. Seville, Córdoba, Doñana marshes. Only navigable river (to Seville).
4. Guadiana: 742 km (shared with Portugal). Badajoz, Alqueva Dam (Europe's largest reservoir).
5. Júcar: 498 km. Valencia region, rice, orange groves.

Other Notables

• Duero (Douro) — wine, Portugal border.
• Miño (Minho) — Galicia/Portugal.
• Segura — Murcia, heavily managed.
• Turía — Valencia (diverted, now park).

Challenges

Overextraction, pollution, dams, climate change, inter-basin transfers (Tagus–Segura). Water wars define Spanish politics.
