Luq'umayu

Luq'umayu (Quechua luq'u old hat that has lost ist form; hollow, depression (of an area), mayu river, "hollow river", hispanicized spellings Lucumayo, Lucumayu) is a river in Peru located in the Cusco Region, La Convención Province, Huayopata District. Its waters flow to the Willkanuta River.

Luq'umayu originates in the Urupampa mountain range near Willka Wiqi. It crosses the district from southeast to northwest along the villages of Chachayuq (Chachayoc), Allpamayu (Alfamayo), Luq'umayu (Lucumayo), Wak'arumiyuq, (Huacarumiyoc), Wamanpata (Huamanpata), Inkatampu (Incatambo), Sarasarayuq (Sarasarayoc), Wamanmarka (Huamanmarca) and Huyru (Huyro). Some of its numerous little affluents from the right are Allpamayu, Ch'akimayu (Chaquimayo), Inkatampu (Incatambo) and Sirinayuq (Sirinayoc). Its main tributary is Wamanmarka (Huamanmarca). The village of Wamanmarka lies near the confluence of these rivers, on the right bank of the Luq'umayu. This is where the archaeological site of Wamanmarka is situated. Tunkimayu ("Andean cock-of-the-rock river", Tunquimayo) is one of the left tributaries.

East of Wamanmarka the river turns to the west and keeps this direction up to the confluence with the Willkanuta River as a right affluent. It is east of Pampayuq (Pampayoc) on the border of the districts of Huayopata, Maranura and Santa Teresa.
