The Chiese, also known in the Province of Brescia as the Clisi, is a 160 km Italian river which is the principal immisary and sole emissary of the sub-alpine lake Lago d’Idro, and is a left tributary of the Oglio.
The river rises from the Adamello in Trentino and runs through the Val di Fumo and the Val di Daone forming the reservoirs Lago di Malga Bissina and Lago di Malga Boazzo. At Pieve di Bono if enters the lower valleys of Giudicarie receiving the waters of the torrente Adanà. Further south it flows into Lago d'Idro near Baitoni and enters Lombardy and the Province of Brescia.
After leaving the lake the river runs through the Val Sabbia as far as Roè Volciano. Here it enters the pianura padana, and flows south through Gavardo, Calcinato, Montichiari, Carpenedolo and Acquafredda, enters the Province of Mantova at Asola, before joining the Oglio from the left in the valley of Acquanegra sul Chiese.
Exploitation as a source of hydropower
Like its twin the Sarca, the river is born of the glaciers of the Parco naturale provinciale dell'Adamello-Brenta and its waters are intensively used for the production of hydro-electricity. Within the highly restricted area of its drainage basin above Lago d’Idro there are at least four artificial lakes and three hydro-electric power stations. The lower course of the river in Lombardy is also used for this purpose.
