Book excerpt: Excerpt from Irrigation in Northern Italy, Vol. 2 Four of the canals described in this report take water from the Adda River; the fifth is supplied from the Adige. The Adda rises on the southern slopes of the Alps, flows through Lake Como, which serves as a natural regulator, and after traversing the foothills south of the lake for several miles, reaches the north boundary of the Po Valley, which it crosses in a southeasterly direction, and empties into the Po near Cremona. The location of the canals studied and the territory irrigated from the Adda are shown on the map. (pl. I.) The first of the canals to be studied was the Martesana. It was inspected in company with Mr. Grossi, the assistant engineer. Its headgate is the highest of all irrigation systems from the Adda, the only. Diversions above that point being for power purposes. The appearance of the valley at the head of the 'martesana is shown in Plate II, figure 1. It is a most picturesque region, but one ill - suited to canal building, as the bluffs bordering the river are high, rocky, and steep. The river at this point has a rapid fall. Its surface is capped with foam as it plunges down over the immense bowlders which obstruct the channel.. Naturally picturesque, the beauty of the scenery of this region has been greatly enhanced by its historic inter est. Many of the bluffs are crowned with the ruins of medieval castles-or with beautifully kept terraced gardens surrounding palaces and villas, which furnish illustrations of the best work in modern architecture and landscape gardening. At the foot of one of the piers of the bridge shown in Plate II, figureq, sthe official gauge rod established by the Government as a basis for determining how the water shall be divided among the canals below, there being no diversions above this point except one for power. On August 19 the river carried cubic feet per sec ond, making it rank at this time of the year with the Snake and Yellowstone among rivers used in irrigation in this country. Its flood fl'ow 1s not so large as these streams, the high water record being 29 190 cubic feet per second, but the low water flow, cubic feet per second, compares favorably with our larger western streams.
