Canonical upper Segura headwater row for the Santiago-Pontones / Fuente Segura area. This is the densest cluster of wild-trout cotos in Andalucía, with sin muerte beats preserving native autóctona genetics and some managed rainbow water in the same upper system. Mountain limestone gorges, karst springs, and compact pocket water make this the main Segura headwater planning row rather than splitting the same upper basin into overlapping entries.
