Camarmilla stream Nature · Camarma de Esteruelas, Cuenca del Medio Jarama, Madrid A minor stream that crosses the district and links several local paths, included within SPA 139 of cereal steppes; nearby, in the Los Prados area, there is a Bronze Age site next to the El Altillo viewpoint. A right-bank tributary of the Henares, it rises in Torrejón del Rey and flows into the Henares at Alcalá de Henares after passing through Camarma de Esteruelas; reeds, bulrushes, canes and willows grow along its floodplain, home to species such as the great bustard, the harrier and the ocellated lizard. The Romans founded Complutum at the fork formed by its confluence with the Henares, and its rain-fed land is today devoted mainly to cereal farming.
