Within the last few years the character of the river and of the country adjacent to it has materially changed, and inferences drawn from present conditions may be erroneous. This change is the direct result of the recent stocking of the country with cattle. More cattle have been brought into the country than in its natural state it will support. One of the results of this overstocking is a very high death rate among the cattle; another and more important result is that the grasses and other vegetation have no chance to seed or mature, being cropped off close to the ground almost as soon as they appear. As a result of this, many of the river terraces and little valleys among the foothills, once celebrated for luxuriant grass, are now bare, and would hardly afford sustenance to a single cow for a week. In place of strong grasses these places are now covered for a few weeks in spring with a growth of a plant known as “filaree,” which, owing to the rapid maturing of its seeds (in a month or less), seems to be the only plant not completely destroyed by the cattle, although the latter are very fond of it and eat it freely, both green and when dried on the ground. As a further effect of the abundance of cattle and the scarcity of food for them, the young willows, which, even so late as ten years ago, formed one of the characteristic features of the river and its banks, growing thickly in the bed of the stream, and often forming impenetrable jungles on its banks, are now rarely seen. Owing to the character of the country it drains, the Rio Verde always must have been subject to freshets and overflows at the time of the spring rains, but until quite recently the obstructions to the rapid collection of water offered by thickly growing grass and bushes prevented destructive floods, except, perhaps, on exceptional occasions. Now, however, the flood of each year is more disastrous than that of the preceding year, and in the flood of February, 1891, the culminating point of intensity and destructiveness was reached. On this occasion the water rose in some places over 20 feet, with a corresponding broadening in other places, and flowed with such velocity that for several weeks it was impossible to cross the river. As a result of these floods, the grassy banks that once distinguished the river are now but little more than a tradition, while the older terraces, which under normal circumstances would now be safe, are being cut away more and more each year. In several localities near Verde, where there are cavate lodges, located originally with especial reference to an adjacent area of tillable land, the terraces have been completely cut away, and the cliffs in which the cavate lodges occur are washed by the river during high water.
