The Oglio (Italian: [ˈɔʎʎo] ; Latin : Ollius or Olius; Lombard : Òi, Cremonese : Ùi) is a left-side tributary of the river Po in Lombardy, Italy. It is 280 kilometres (170 mi) long. In the hierarchy of the Po's tributaries, with its 280 kilometres (170 mi) of length, it occupies the 2nd place per length (after the river Adda), while it is the 4th per basin surface (after Tanaro, Adda and Ticino), and the 3rd per average discharge at the mouth (after Ticino and Adda).

Overview

The Oglio is formed from the confluence of two mountain streams, the Narcanello branch from the Presena Glacier, in the Adamello group and the Frigidolfo branch, in the Corno dei Tre Signori, part of the Stelvio National Park. The streams merge near Pezzo di Ponte di Legno, both the streams have an average discharge of 1.5 m3/s (53 cu ft/s). The Frigidolfo branch, before merging with Narcanello branch, receives the Arcanello branch, which have an average discharge of 0.5 m3/s (18 cu ft/s), which receives a minor branch originating from Lake Ercavallo. The Ogliolo stream, with an average discharge of 2.5 m3/s (88 cu ft/s) and a length of 20 kilometres (12 mi) (similar to the length of the main branch between the Frigidolfo-Narcanello merge at Ponte Di Legno and the Oglio-Ogliolo merge at Edolo) is sometimes considered as a de facto fourth branch of the Oglio river.[ citation needed ]

It flows in a southwest direction, through Valcamonica and enters into the Lake Iseo at Costa Volpino. It leaves Lake Iseo at Sarnico and, after traveling a zone of moraine deposits, it joins the Po river 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 6,649 square kilometres (2,567 sq mi). It is part of the larger Po-Adige basin.[ citation needed ]

Po Valley section

The Oglio main branch leaves the lake at the provincial border between Sarnico, Bergamo and Paratico, Brescia 45°39′56.5″N09°57′24″E / 45.665694°N 9.95667°E / 45.665694; 9.95667 and begins to follow (approximately) this provincial border. At the triple provincial border between Torre Pallavicina (Bergamo), Roccafranca (Brescia) and Soncino (Cremona) 45°25′40.5″N09°53′07.5″E / 45.427917°N 9.885417°E / 45.427917; 9.885417 the Oglio begins to follow (approximately) the provincial border between the Brescia-Cremona provincial border.

The major tributaries in the Po valley are the following:

At this triple provincial border the Oglio river begins following the Mantua-Cremona provincial border, which leaves at the triple municipal border between Acquanegra sul Chiese (Mantua), Calvatone (Cremona) and Bozzolo (Mantua) 45°07′57″N10°29′32″E / 45.13250°N 10.49222°E / 45.13250; 10.49222 where the river enters entirely in the Mantua province.

At the municipal border between Marcaria and Viadana 45°02′40″N10°39′37″E / 45.04444°N 10.66028°E / 45.04444; 10.66028 , the Oglio river enters the Po river.
