The [[Vardar]] river, which flows through Skopje, is at approximately {{cvt|60|km|abbr=off}} from its source near [[Gostivar]]. In Skopje, its average discharge is 51 m<sup>3</sup>/s, with a wide amplitude depending on seasons, between 99.6 m<sup>3</sup>/s in May and 18.7 m<sup>3</sup>/s in July. The water temperature is comprised between 4.6&nbsp;°C in January and 18.1&nbsp;°C in July.<ref name="vardar">{{cite web |url=http://www.kuke.com.pl/download.php?id=9 |title=Combined Cycle Co-Generation Power Plant Project, Skopje, Environmental Assessment Report |publisher=TE-TO AD SKOPJE |year=2006 |access-date=6 October 2012 |url-status=dead |archive-url=https://web.archive.org/web/20090816180417/http://www.kuke.com.pl/download.php?id=9 |archive-date=16 August 2009}}</ref>

Several rivers meet the Vardar within the city boundaries. The largest is the [[Treska]], which is {{cvt|130|km|abbr=off}} long. It crosses the [[Matka Canyon]] before reaching the Vardar on the western extremity of the City of Skopje. The [[Lepenac]], coming from [[Kosovo]], flows into the Vardar on the northwestern end of the urban area. The Serava, also coming from the North, had flowed through the [[Old Bazaar, Skopje|Old Bazaar]] until the 1960s, when it was diverted towards the West because its waters were very polluted. Originally, it met the Vardar close to the seat of the [[Macedonian Academy of Sciences and Arts]]. Nowadays, it flows into the Vardar near the ruins of [[Scupi]].<ref>{{cite web |url=http://star.vest.com.mk/default.asp?id=40399&idg=3&idb=604&rubrika=Revija |title=Одмаздата на Серава |year=2001 |publisher=Vest |author=Risto Ḱorstošev |access-date=6 October 2012 |url-status=dead |archive-url=https://web.archive.org/web/20131023061721/http://star.vest.com.mk/default.asp?id=40399&idg=3&idb=604&rubrika=Revija |archive-date=23 October 2013}}</ref> Finally, the Markova Reka, the source of which is on Mount [[Vodno]], meets the Vardar at the eastern extremity of the city. These three rivers are less than {{cvt|70|km|abbr=off}} long.<ref name="figures"/>

[[File:Кањон.jpg|thumb|The [[Matka Canyon]] and the [[Treska]], on the western edge of the City of Skopje]]
The City of Skopje incorporates two artificial lakes, on the Treska. The lake Matka is the result of the construction of a dam in the Matka Canyon in the 1930s, and the Treska lake was dug for leisure purpose in 1978.<ref name="figures"/> Three small natural lakes can be found near Smiljkovci, on the northeastern edge of the urban area.

The river [[Vardar]] historically caused many floods, such as in 1962, when its outflow reached 1110 m<sup>3</sup>/s<sup>−1</sup>.<ref name="vardar"/> Several works have been carried since Byzantine times to limit the risks, and since the construction of the Kozjak dam on the Treska in 1994, the flood risk is close to zero.<ref name="kozjak">{{cite web |url=http://www.jasen.com.mk/Default.aspx?id=1703cd5c-b351-44f8-a60d-8108b7a76e5a |title=Lake Kozjak |author=Jasen |year=2010 |publisher=Government of the Republic of Macedonia |access-date=27 February 2011}}</ref>

The subsoil contains a large [[water table]] which is alimented by the Vardar river and functions as an underground river. Under the table lies an [[aquifer]] contained in [[marl]]. The water table is 4 to 12 m under the ground and 4 to 144 m deep. Several wells collect its waters but most of the drinking water used in Skopje comes from a [[karst]]ic spring in Rašče, west of the city.<ref name="nature"/>
