The present case is a suit for damages to machinery, merchandise and manufacturing materials caused by high waters and brought by a plaintiff whose plant was located on Fishing Creek and upstream from a bridge thereon. The defendant’s dam was approximately four miles upstream on the Oconee River from the confluence of that stream with Fishing Creek. There was a verdict for the defendant and the plaintiff brings error to this court based on exceptions to various charges of the court as given and to the failure of the court to give in charge to the jury various charges set out in the grounds of the motion for new trial. There seems to be a basic disagreement between the parties as to the law of this State relating to upper and lower riparian owners in the situation here involved as set forth in headnote 5 which requires further elaboration.
Plaintiff contends it is the law of this State that the owner and operator of a dam must anticipate freshet and flood conditions *97 and operate its dam so as to have storage capacity to meet such anticipated conditions, and in effect operate the dam as a flood control dam. There are exceptions to charges given and exceptions as to the failure to charge which are dependent upon the validity of this claim.
A proper decision of this case (on some of the exceptions to the charge as given and to the failure to give certain charges without request) depends upon the answer to two questions: (1) What is the duty owed by the owner and operator of a hydro-electric dam to a lower riparian owner? and, (2) has the “law of the case” here, by reason of the overruling of the special demurrers to certain allegations of negligence in the petition, established a different rule solely applicable to the present case? The case of
Brown v. City of Atlanta,
“4. ‘The city or its agents would have the right to let off the *98 water for all proper purposes of the works, if done in such quantities as would keep within and not overflow the adjacent lands below, when the stream was in its ordinary condition—its condition not in the time of floods or freshets, but its condition generally and at ordinary times between freshets, and if the water was let off in quantities no greater than the channel would reasonably contain within the banks at ordinary times, then if it happened that on some occasion or occasions, the channel was already in whole or in part filled or occupied by high water, so that there was not room for both together to flow off harmlessly, and in that manner the plaintiff’s lands were overflowed, this would give no cause of action. The court is of opinion that, at such times of high water or partially high water, the city would not have to stop reasonable and proper operation any more than any factory or mill would have to stop the water from its wheels in like times for fear of making or increasing an overflow below. The city would have no right to let off more water or at greater rate than would be safe and prudent to proprietors below, when the channel was open and free to receive it and carry it off, and if no more than that was discharged from the dam, the defendant would not be liable, whether the plaintiff was injured or not. If more was discharged and plaintiff’s crops were injured thereby, then he could recover for the injury to the extent of the same.’
“5. ‘Again, it would be the duty of the city and its officers and agents having charge of the works, to use ordinary diligence in letting off the water, that is, to take such care as a prudent person would take were the whole risk his own. If you find that the water was let off for causes that were reasonable and proper, and was done with appliances adapted for the purpose, at a rate no greater than a prudent person would, by those causes and using that dam and those appliances, have used and deemed safe to himself had he been also proprietor, as plaintiff was, on the stream below there, the plaintiff would not recover.’
“6. ‘That the plaintiff’s land was injured would not be sufficient. It must further appear that the negligence caused the injury or injuries; not that it contributed to injury or injuries mainly arising from other causes. The defendant’s negligence *99 must be the chief cause, the preponderating, controlling cause, before it could be the subject of a recovery. If the injury or injuries in question were caused mainly by heavy rainfalls escaping through the water-works’ stream or coming down in other streams, pouring in above plaintiff’s land, and if these were the main, substantial, preponderating causes of the overflow of plaintiff’s land, then he could not recover, even though there was negligence, and even though such negligence added to or increased the injury in some minor and uncertain degree. The negligence complained of must be the main, controlling and preponderating cause, ascertained and distinguished from other causes, in order to be the subject of a recovery.’ ”
The case of
Brown v. City of Atlanta
was followed generally in
Carroll v. City of Atlanta,
In
Grant v. Kuglar,
A statement in
It is contended by the plaintiff, that if the law of this State does not require the operation of a dam for the purposes of flood control, the law of the case as established by the overruling of special demurrers to allegations of negligence contained in the petition, unexcepted to, does, and that this law of the case should apply. This contention is based upon the overruling of special demurrers to the allegations of negligence contained in paragraph 34 (a) of the petition, as follows: “In maintaining its reservoir at peak capacity when weather and inflow conditions were such as to reasonably indicate an immediate and continuing need for additional controllable storage capacity.” The demurrer was on the grounds that “there was no legal obligation on defendant to maintain its reservoir below peak capacity so as to be able to catch or store
unprecedented floods
coming into
*101
its reservoir.” (Emphasis by the court). It is obvious that this demurrer is a speaking demurrer as the allegation of negligence makes no mention of unprecedented floods, that is, unforeseeable floods, but refers solely to indicated, and thereby foreseeable, inflow of water into the reservoir. A speaking demurrer, or a demurrer which is so defective as to be ineffective as a demurrer, should be overruled. See
Oxford v. Shuman,
*102 Judgment affirmed.
