The Po marks the southern border of the region for approximately {{cvt|210|km|0}}; its major tributaries are the [[Ticino (river)|Ticino]], which rises in the Val Bedretto in [[Switzerland]] and joins the Po near Pavia,<ref>{{cite book|author1=Rodolfo Soncini-Sessa|author2=Enrico Weber|author3=Francesca Cellina|author4=Francesca Pianosi|title=Integrated and Participatory Water Resources Management - Practice|publisher=Elsevier Science|year=2007|isbn=9780080551425|page=40}}</ref> the [[Olona]], the [[Lambro]], the [[Adda (river)|Adda]], the [[Oglio]] and the [[Mincio]].

The numerous lakes of Lombardy are all of glacial origin and are located in the northern highlands. From west to east, these lakes are: [[Lake Maggiore]], [[Lake Lugano]] (both shared with Switzerland), [[Lake Como]], [[Lake Iseo]], [[Lake Idro]], and [[Lake Garda]] (the largest lake in Italy).<ref>[[Gabriel Faure (writer)|Gabriel Faure]] (1923). ''The Italian Lakes: Maggiore, Como, Orta, Varese, Lugano, Iseo, Garda''</ref> South of the Alps lies a succession of low hills of [[Moraine|morainic]] origin that were formed during the [[Last Glacial Period]],as well as small, barely fertile plateaux with typical heaths and conifer woods. A minor mountainous area, the [[Oltrepò Pavese]] lies in the [[Apennines]] range south of the Po.<ref name="oltresentieri"/>

The [[navigli]] are a system of interconnected [[canal]]s in and around [[Milan]], dating back as far as the Middle Ages.<ref>{{Cite web |last=Florensa |first=Lídia |title=Navigli: guía para visitar los canales de Milán |url=https://www.viajarmilan.com/visitar-los-canales-navigli.php |access-date=7 February 2023|website=Viajar Milán |language=es}}</ref> The system consists of five canals: [[Naviglio Grande]], [[Naviglio Pavese]], [[Naviglio Martesana]], [[Naviglio di Paderno]], and [[Naviglio di Bereguardo]]. The first three were connected through Milan via the ''Fossa Interna'', also known as the Inner Ring. The urban section of the [[Naviglio Martesana]] was covered over at the beginning of the 1930s, together with the entire Inner Ring, thus sounding the death knell for the northeastern canals.
