'''Olmos District''' is one of twelve districts of the province Lambayeque in Peru.<ref>{{in lang|es}} Instituto Nacional de Estadística e Informática. ''[http://desa.inei.gob.pe/mapas/bid/ Banco de Información Distrital] {{webarchive|url=https://web.archive.org/web/20080423164200/http://desa.inei.gob.pe/mapas/bid/ |date=2008-04-23 }}''.

==History== The name of the district comes from the town of Olmos, meaning "elms", because the pale bark of the trees in the surrounding forest reminded the Spanish settlers of the elm trees back in Spain. At the time of the arrival of the Spaniards the area was occupied by the Quechuas and the extensive region of Olmos was administered by the Kingdom (''curacazgo'') of Copiz, which was under the Inca Empire. The pre-existing town was recognized in 1544 by the viceroy Blasco Núñez Vela.

==Hydrographics== The major river in the district is the Olmos River.<ref name="Hydrography">{{Cite web|title=Distrito de Olmos: Hidrografía|publisher=Municipalidad Distrital de Olmos|url=http://www.muniolmos.gob.pe/paginaolmos/html/orografia.htm |archiveurl=https://web.archive.org/web/20080905153622/http://www.muniolmos.gob.pe/paginaolmos/html/orografia.htm |archivedate=5 September 2008|url-status=dead}}</ref> Other important rivers are the Cascajal River, the Insculás River, the Ñaupe River, and the San Cristóbal River.<ref name="Hydrography" /> The Limón Dam is part of the Olmos irrigation project which is intended to irrigate dry region west of the Andes by damming the flood-prone Huancabamba River.<ref>{{Cite web|author=Direccion General de Electridad, Ministerio de Energia y Minas, Republica del Peru |title=Evaluacion del Potencial Hidroelectrico Nacional Volume XII, Cuencas Costa Norte|url=http://www.minem.gob.pe/minem/archivos/file/Electricidad/potencial/Volumen12/PeruPotHidro_vol12.pdf |archiveurl=https://web.archive.org/web/20130118000538/http://www.minem.gob.pe/minem/archivos/file/Electricidad/potencial/Volumen12/PeruPotHidro_vol12.pdf |archivedate=18 January 2013 |url-status=live}}</ref>
