present in this instance. It is obvious that there are no definite guide posts provided and that necessarily much must be left to judgment and discretion. The breadth and boundaries of this area of discretion are well stated in Restatement of the Law, Torts, § 852c in these words: "The determination in a particular case of the unreasonableness of a particular use is not and should not be an unreasoned, intuitive conclusion on the part of the court or jury. It is rather an evaluating of the conflicting interests of each of the contestants before the court in accordance with the standards of society., and a weighing of those, one against the other. The law accords equal protection to the interests of all the riparian proprietors in the use of water, and seeks to promote the greatest beneficial use of the water, and seeks to promote the greatest beneficial use by each with a minimum of harm to others. But when one riparian proprietor's use of the water harmfully invades another's interest in its use there is an incompatibility of interest between the two parties to a greater or lesser extent depending on the extent of the invasion, and there is immediately a question whether such a use is legally permissible. It is axiomatic in the law that individuals in society must put up with a reasonable amount of annoyance and inconvenience resulting from the otherwise lawful activities of their neighbors in the use of their land. Hence it is only when one riparian proprietor's use of the water is unreasonable that another who is harmed by it can complain, even though the harm is intentional. Substantial intentional harm to another cannot be justified as reasonable unless the legal merit or utility of the activity which produces it outweighs the legal seriousness or gravity of the harm."
In all our consideration of the reasonable use theory as we have attempted to explain it we have accepted the view that the benefits accruing to society in general from a maximum utilization of our water resources should not be denied merely because of the difficulties that may arise in its application. In the absence of legislative directives, it appears that this rule or theory is the best that the courts can devise.
