The natural flow of the Xerias has been modified by river engineering, including the creation of pumping stations and reservoirs to control seasonal flooding, improve sanitation, and provide more stable water supplies for agricultural and human use.
[2]: 128 In addition, some scientists are of the opinion that the removal of wetlands near the mouth of the Xerias to control the spread of mosquitoes and malaria has paradoxically increased area water use in winter because a changing microclimate due to wetlands removal has increased the incidence of frost on local farmers' citrus trees (sprinklers are used to prevent frost build-up).
On April 25, 1821, the Xerias became the site of a battle between Greek forces and Turks for control of Argos, led by Mustafa, deputy (kehya bey) to the absentee Turkish governor of the Morea, Hurshid Pasha.
The Greeks in the town were led by a triumvirate of Paparsenis Krestas, Demetrios Tsorkis, and Ioannis Yiannouzas, the eldest son of admiral Laskarina Bouboulina.
Yiannouzas was slain, along with about 700 other Greeks, including civilians, and according to local accounts, many women and girls were captured by the Turks and sold into slavery.
