COMO, a lake in the Austrian kingdom of Venetian Lombardy. It is formed by the water of the river, and of more than one hundred and ninety small brooks and rivulets that empty themselves into it. Its whole length is about thirty-five miles, but its breadth scarcely in any part exceeds three miles. Its elevation above the sea is about 700 feet. The southern portion of the lake is divided into two branches, the shorter of which, running south-west, extends to the town of Como, and the longer south-east to Vapres, near Bergamo. The surrounding country is picturesque and beautiful. The banks exhibit vineyards, olives, and mulberry trees in great abundance, and the lake abounds in fish.
