The Guadiela has its source in the Serranía de Cuenca (es), near Cueva del Hierro,^[3] at the Fuente Pinilla site.^[4] It flows from East to West for 117 kilometres (73 mi),^[2] passing through the Spanish province of Cuenca, emptying into the Tagus at the Bolarque reservoir,^[5] on the border between the provinces of Cuenca and Guadalajara. It is dammed upstream by the Buendía reservoir (es).^[1]

It receives the waters from the Cuervo (es), Guadamejud (es), Mayor (es) and Trabaque (es).^[2]

The hydronym Guadiela is formed by 'Guad' (of Arabic origin, conveying the meaning of "river") and the '-iela' suffix (a diminutive).^[6]
