Amarguillo

The watercourse originates to the north of the Collado de la Mirla (in the Sierra de la Calderina [es], a subrange of the Montes de Toledo) within the Spanish municipality of Urda.^[3][4] Featuring a catchment area of around 563 km², the river runs for 55 kilometers mostly in a west-east direction near the fringes of the Montes de Toledo.^[2] Historically, the river has been the site of multiple catastrophic floods, including the 1891 one, in which the river reached an estimated flow by Consuegra of 114 m³/s.^[5] It passes near the Spanish municipalities of Urda, Consuegra, Madridejos, and Camuñas.^[6] Also known as arroyo de Valdespino in its lower course, it discharges into the Cigüela in the province of Ciudad Real.^[7]
