This action was instituted by the plaintiff against Boise City to recover damages caused by flooding and overflowing her property and the property of twenty others whose claims for damages had been assigned to the plaintiff.
It appears that on about the 19th of June, 1909, a heavy rainfall, or what is commonly called a cloudburst, occurred in the foothills east of Boise City and in the vicinity of what is known as Cottonwood canyon. As a result a large body of water collected in the Cottonwood creek and carried a great quantity of sand, gravel and debris down the stream and deposited it on the town lots of the plaintiff and her assignors, doing great damage to the lots and flooding cellars and causing damage to the persons whose lots were flooded. It ap *138 pears that in the early settlement of Boise City this stream in its natural course flowed down through what is now embraced in the lands of the Boise Barracks, and thence through the center of the present city and in the vicinity of the Capitol Building. This resulted in flooding and overflowing large tracts of land during the high-water season and at times of heavy rainfall, and so the city finally concluded to divert the course of the stream from the mouth of the canyon, and accordingly built what is designated as the “Cottonwood flume,” carrying the water almost in a southerly direction from the mouth of the canyon to the Boise river. This resulted in diverting the entire flow of the stream from its original course as it formerly left the mouth of the canyon and carries the water through a territory that had not previously been affected by the flow of the stream. It seems that at first the retaining walls along the east side of the military reserve were not built high enough to retain the water and prevent it overflowing the military reserve at times of extraordinary high water, and so the government caused the wall to be erected higher and in a more substantial manner for some distance along the government property, thus holding the water and carrying it past the reserve. From thence to the Boise river the water is carried through a canal that is walled up on each side by substantial stone walls. The lots belonging to the plaintiff and her assignors lie on the east side of this canal. It seems that the canal is only large enough to carry the stream of water at ordinary high water, but is not large enough to carry off the volume of water that comes down the stream at extreme high water or at times of cloudbursts or extraordinary heavy rains. Many years ago the city caused a dam to be constructed across the Cottonwood creek at the mouth of the canyon, and immediately above the government retaining wall, for the purpose of causing an eddy in the stream and precipitating the large volume of sand that comes down the stream so as to prevent the greater quantity of the sand being carried into the canal. This dam was not a permanent or substantial structure. It appears that it had been constructed in a rather careless and negligent and temporary *139 manner. When the heavy rain or what is termed a cloudburst occurred in June, 1909, this dam was carried out, and with it large volumes of sand, silt and debris were swept along by the flood and precipitated upon the lots of the plaintiff and her assignors.
There is no dispute in this case but that the injury and damage complained of was committed. The city does not dispute the fact that the lots were flooded and debris and sand deposited thereon, and the cellars and other excavations were flooded. It is insisted, however, by the city that it is not liable for this occurrence, and this contention is based upon the fact that it claims this was an unprecedented and unusual flood, and that it therefore falls within that class of occurrences which are attributed to
vis major
or act of God, for which there is no human responsibility. There is no occasion for citing or reviewing authorities to the effect that no responsibility attaches to the city if this act can be termed an act of God. This court has twice had occasion to so hold on similar questions.
(Axtell v. Northern Pacific R. Co.,
The decisive question, however, arises in this ease as to what constitutes vis major or the act of God within the meaning of the law of negligence. Black, in his Law Dictionary, defines it thus: “Any misadventure or casualty is said to be caused by the ‘act of God’ when it happens by the direct, immediate, and exclusive operation of the forces of nature, uncontrolled or uninfluenced by the power of man and without human intervention, and is of such a character that it could not have been prevented or escaped from by any amount of foresight or prudence, or by any reasonable degree of care or diligence, or by the aid of any appliances which the situation of the party might reasonably require him to use.”
The English court in Nitrophosphate etc. v. London etc. Docks Co., L. R. 9, Ch. Div. 516, said: “To say that the thing could not reasonably have been anticipated is to say that it was the act of God.”

Kansas City v. King,
“It is true that the flood of 1892 may be said to have been an unusual one, but, although unusual, it was such as had occasionally occurred, ancT which the city should have anticipated and provided against. The testimony shows that such floods had occurred at irregular intervals, and that' they would again occur might reasonably have been expected. It is true that floods unprecedented and so extraordinary as to have been beyond reasonable anticipation are not to be provided against, but, while floods like the one which occasioned the injury were of rare occurrence in that vicinity, they had occurred so often in the past as to warrant the belief that the region was subject to them, and that, under the laws of nature, they would occur again. Ordinary care and foresight, therefore, *141 required the city to provide against floods which were or should have been anticipated, and floods were shown to have occurred so frequently that those who constructed the sewers should have anticipated floods like that of 1892, and should have guarded against them by placing flood gates at the mouths of the sewers.”
In
Ohio & Mississippi Ry. Co. v. Ramey,
“The principle clearly is, that although a rainfall may be more than ordinary, yet if it be such as has occasionally occurred, and, it may be, at irregular intervals, it is to be foreseen that it will occur again, and it is the duty of those changing or restraining the flow of water to provide against the consequences that will result from it. It is within the knowledge of all who have long resided in this state, that our streams are occasionally subject, after intervals which are sometimes of shorter and at other times of longer duration, to great floods, occasioned by very heavy rainfalls, and their heights are known by those who have felt interested in them. Such rainfalls were not usual and ordinary, but they were unusual and beyond ordinary, — i. e., they were extraordinary; and yet it is just as certain that like rainfalls will occur in the future as it is that the same laws of nature by which they are produced, and the same conditions to be affected by those laws, will continue to exist in the future as they have in the past. Though of rare occurrence, such rainfalls are not phenomenal, and therefore beyond reasonable anticipation, and it is hence but the prudence that a discreet man would exercise in his own affairs to provide against injury from them. The question, then, is not whether appellant has sufficiently provided for the escape of water of ordinary floods, but has it provided for the escape of the water of such unusual or extraordinary floods as it should have anticipated would occasionally occur in the future, because they had occasionally *142 occurred after intervals, though of irregular duration, in the past.” (See Gulf, C. & S. F. Co. v. Boyce,39 Tex. Civ. App. 195 ,87 S. W. 395 ; Central Trust Co. v. Wabash, St. L. & P. Ry. Co.,57 Fed. 441 ; Mahaffey v. Rumbarger Lumber Co.,61 W. Va. 571 ,56 S. E. 893 , 8 L. R. A., N. S., 1263; Hyman v. Hauff,138 N. Y. 48 ,33 N. E. 735 .)
In the case at bar, the city, in the first place, as a municipality, was not obliged to divert the flow of Cottonwood creek from its original natural channel through the city. It had the power, however, to do so.
(Willson v. Boise City,
This question arose between the same parties in
Willson v. Boise City,
■ Eeturning again to the facts of this case, it appears that these heavy rains or cloudbursts, such as occurred on the 19th of June, 1909, and for which damages are claimed, only occur at intervals of two, three, four or five years apart. It seems that almost every year in the spring and early summer heavy rainfalls occur in the vicinity of Cottonwood creek, and that as a consequence large volumes of water come down the stream, but these cloudbursts referred to as unusual and extraordinary do not occur every year, but have occurred a number of times within the last fifteen or twenty years; in other words, they have occurred with sufficient frequency within the memory of man that they cannot be classed among the phenomenal or unprecedented outpourings of nature against which the city could not have reasonably provided or which could not have been reasonably guarded against. If it appeared in this case that this was such a heavy and unprecedented rainfall as had not occurred within the memory of man, as *144 that term is defined by law, then certainly the city would not be liable. Such an act would properly be classed as the act of God for which there is no liability.
We are fully persuaded from the facts as they appear in the record in this ease that Boise City has been negligent in maintaining this canal, and the sooner the municipality wakes up to its responsibility and duty in this respect, the better it will be for the whole people, both in their collective capacity as a municipality and their individual capacity as citizens and taxpayers. The city has undertaken the care and maintenance of this stream. It must now afford the property owner reasonable protection against the ravages of the stream in times of high water. This court in Willson v. Boise City, supra, twelve years ago, sounded the alarm to the city that it must take care of the waters from this stream, but the admonition seems to have gone the way of much good advice in this world, and now the city must pay in. dollars and cents for what it might have reasonably prevented and protected the citizens against.
The judgment in this case should be affirmed, and it is so ordered. Costs awarded in favor of respondent.
