The River Oglio

[The river in Palazzolo sull'Oglio, lower Brescia]
The Oglio River is a river which runs directly through, north to south, the Camunian Valley. It begins in high Alpine mountain streams. Some of its more impressive stretches run through the Val Camonica, where it feeds Lake Iseo. It continues out of the lake, and down to the province of Mantua. The river is cammed "Òi" in the Lombard language, and the Camunian dialect.

The Oglio (Latin Ollius, or Olius; Lombard Òi) is a left-side tributary of the Po River in Lombardy, Italy. It is 280 km long.

The Oglio is formed from the confluence of two mountain streams, the Narcanello from the Presena Glacier, and the Frigidolfo, from Lake Ercavallo, in the Stelvio National Park. These two streams are born at the points of the Corno dei Tre Signori, at an altitude of about 2600 m. The streams merge near Pezzo di Ponte di Legno.

It flows in a southwest direction, through Valcamonica and then Lake Iseo. It joins the Po after traveling a zone of morraine deposits, at Torredoglio, not far from Cesole and Scorzarolo, in the province of Mantua. Its drainage basin, which corresponds to the region of Valle Camonica, covers 6649 km². It is part of the larger Po-Adige basin.

On the Wikipedia link above, there is a map of the river, but it's not especially clear. In the Val Camonica Wikipedia page, under "Hydrography," it states: The Valle Camonica is crossed by the River Oglio, the fifth longest river of Italy, which was born in Ponte di Legno from the confluence of rivers Frigidolfo and Narcanello. It flows into Lake Iseo between the municipalities of Pisogne and Costa Volpino. If you look at the Italian Oglio Wikipedia page, you can see a few good photographs of the river.
