Plaintiffs, owners of lands riparian to Nicasio Creek in Marin County, appeal from a summary judgment for defendant entered in an action in inverse condemnation for damages resulting from defendant’s construction of a dam across said creek at a point above plaintiffs ’ lands.
Plaintiffs’ third amended complaint (complaint) alleges that since March 1955 plaintiffs have been, and now are, the owners of a parcel of five acres of land; that a stream (Nicasio Creek) runs through their property; that the normal flow of the waters of the stream carried in suspension rock, sand and gravel which were deposited on plaintiffs’ lands; that plaintiffs operated on their property a rock and gravel business in the course of which they sold and used the deposits of rock and gravel; that defendant is a municipal water district organized and existing under the Municipal Water District Act of 1911; that prior to May 1962 defendant constructed a dam across Nicasio Creek; that as a result the normal flow of waters in said stream was obstructed to such an extent that “the normal and usual replenishment of rocks *135 and gravel’’ upon plaintiffs’ lands ceased; that the value of plaintiffs’ lands was thereby diminished in the amount of $250,000, and that plaintiffs had been deprived of gravel and rock having an accrued value of $25,000 at the time of filing the complaint.
Defendant moved for summary judgment. The declaration of its general manager, filed in support of the motion, states that defendant duly filed its application with the State Water Rights Board (board) for a permit to appropriate and store unappropriated waters from Nicasio Creek for municipal water supply purposes (Wat. Code, §§ 1250-1266) ; that it published notices of its application as required by law (Wat. Code, §§ 1300-1316); that protests to the application (Wat. Code, § 1330), none of which were by plaintiffs, were filed with and duly resolved by the board; that the board issued its permit on May 31, 1961 (Wat. Code, §§ 1340-1353); that pursuant to plans approved by the board (see Wat. Code, §§ 1382, 1393) the dam was constructed and completed on August 21, 1961, and defendant began to store water pursuant to its permit; that defendant had no notice that plaintiffs claimed any right to use the waters of Nicasio Creek for the purposes stated in their complaint until plaintiffs’ claim was presented to defendant on April 3, 1963; that plaintiffs’ lands are approximately one mile downstream from defendant’s dam with other riparian owners intervening; and that defendant did not physically enter upon or take by eminent domain any of plaintiffs’ real property by constructing the dam or reservoir.
Plaintiffs’ declaration filed in opposition to the motion merely states that at no time up to the completion of the Nicasio Dam on August 21, 1961, did - plaintiffs have actual knowledge of any application made to the board to use, store or divert water nor did they receive any notice of defendant "s intention to do so.
The court granted defendant’s motion for summary judgment “upon the ground there was no substantive right of plaintiffs violated by defendant. ’' 1
With some variance in language the parties assert *136 that the principal issue before us is whether defendant, an upstream appropriator of water, is liable in damages to plaintiffs, downstream riparian owners, by reason of having appropriated the waters of the creek under the above-mentioned circumstances.
To bring this appeal into focus, we must first briefly review the growth and development of California water law. In its first stage which began with the “gold rush,” this law dealt mainly with those who diverted water from streams in the public domain for mining purposes and sought to adjudicate the competing claims of the parties using such water on the basis of a principle of prior appropriation.
2
Subsequently with the increasing importance of agriculture over mining, the courts became more involved with riparian rights. (See fn. 2,
ante,
address by Shaw, C. J.,
It was inevitable that the claims of appropriators and riparian owners would collide and that the legal principles upon which they were asserted would appear to be in conflict.
*137
Reconciling these principles,

this court in the leading case of
Lux
v.
Haggin, supra,
Thereafter, and in apparent response to the
Herminghaus
decision (see
Gin S. Chow
v.
City of Santa Barbara
(1933)
As epitomized in
Peabody,
the amendment is said to declare: “1. The right to the use of water is limited to such water as shall be reasonably required for the beneficial use to be served. 2. Such right does not extend to the waste of water. 3..Such right does not extend to unreasonable use or unreasonable method of use or unreasonable method of diversion of water. 4. Riparian rights attach to, but to no more than so much of the flow as may be required or used consistently with this section of the Constitution.” (
It has been long and clearly settled in California that the effect of the passage of article XIV, section 3, “has been to modify the long-standing riparian doctrine . . . and to apply, by constitutional mandate the doctrine of reasonable use between riparian owners and appropriators, and between overlying owners and appropriators.”
(Tulare Irr. Dist.
v.
*139
Lindsay-Strathmore Irr. Dist., supra,
In
Peabody,
several lower riparian owners sought to enjoin the City of Vallejo, as an appropriator, from storing the waters of a creek by the construction of a dam and thereafter diverting them to municipal uses. Peabody, one of the plaintiffs, asserted a right to have all the waters flow without interruption since by normally overflowing his land they not only deposited silt thereon but also washed out salt deposits on portions of the land. The court held that “this asserted right does not inhere in the riparian right at common law, and as a natural right cannot be asserted as against the police power of the state in the conservation of its waters. This asserted right involves an unreasonable use or an unreasonable method of use or an unreasonable method of diversion of water as contemplated by the Constitution.”
(Peabody
v.
City of Vallejo, supra,
*140 Although, as we have said, what is a reasonable use of water depends on the circumstances of each ease, such an inquiry cannot be resolved in vacuo isolated from statewide considerations of transcendent importance. Paramount among these we see the ever increasing need for the conservation of water in this state, an inescapable reality of life quite apart from its express recognition in the 1928 amendment. 9 On the other hand, unlike the unanimous policy pronouncements relative to the use and conservation of natural waters, we are aware of none relative to the supply and availability of sand, gravel and rock in commercial quantities. Plaintiffs do not urge that the general welfare or public interest requires that particular or exceptional measures be employed to insure that such natural resources be made generally available and should therefore be carefully conserved.
Is it “reasonable,” then, that the riches of our streams, which we are charged with conserving in the great public interest, are to be dissipated in the amassing of mere sand and gravel which for aught that appears subserves
no
public
*141
policy? We cannot deem such a use to be in accord with the constitutional mandate that our limited water resources be put only to those beneficial uses “to the fullest extent of which they are capable,” that “waste or unreasonable use” be prevented, and that conservation be exercised “in the interest of the people and for the public welfare. ” (Cal. Const., art. XIV, §3.) We are satisfied that in the instant case the use of such waters as an agent to expose or to carry and deposit sand, gravel and rock, is as a matter of law unreasonable within the meaning of the constitutional amendment. (See
Peabody
v.
City of Vallejo, supra,
Plaintiffs argue that
Los Angeles County Flood Control Dist.
v.
Abbot
(1938)
In
Abbot
the plaintiff district condemned an easement over a portion of defendant’s property for the construction of a concrete flood control channel to confine and carry off the waters of the Alhambra wash. Such waters had naturally overflowed defendants’ lands depositing thereon a considerable amount of sand and gravel which defendant collected in bunkers and sold. The construction of the concrete channel prevented this overflow and brought to an end the replenishment of rock, sand and gravel. Affirming an award of severance damages in respect to defendants’ lands, not taken for improvement of the channel, the court declared: “We are not here dealing with flood waters which, when of no benefit to a riparian owner or to his land and not used by him, may be taken at will by any person who can lawfully gain access to the stream, but are concerned with a natural flow of water, which, under the established doctrine of the California decisions, is annexed to the soil, not as an easement or appurtenance, but as a parcel.
(Herminghaus
v.
Southern Cal. Edison Co.,
Despite the aforementioned passing reference to article XIV, section 3, the opinion in
Abbot
does not appear to discuss, nor to treat as issues raised therein, questions as to the reasonable use or the reasonable methods of the use of water according to the constitutional test prescribed by article XIV, section 3. It appears especially significant that the opinion not only relied on
Herminghaus
which preceded and indeed precipitated the passage of the 1928 constitutional amendment but also ignored this court’s interpretation of the amendment in
Peabody,
decided only three years before. As we read
Abbot,
the basic reason for this seems to be that the court there was not presented with a controversy between users of water as such, that is between a riparian owner on the one hand and an appropriator on the other, such as prevailed in
Peabody
and now confronts us in the present case.
Abbot
therefore involved no issue of reasonableness which required resolution in adjudicating competing claims to the
use
of the water. Rather, it was concerned with the determination of severance damages consequent upon the condemnation of an easement by a flood control district which did not seek to appropriate or use the waters in question. We need not, and do not, here determine whether the court in
Abbot
properly concluded that the riparian rights in that case extended to the receiving of deposits of rock, sand and gravel and that the interference therewith under the circumstances of that ease was actionable. We point out only that because of the problem confronting it, the
Abbot
court measured the riparian’s property right for severance damage purposes according to the “beneficial use of the flow of the Avater”
(Los Angeles County Flood Control Dist.
v.
Abbot, supra,
Apart from their reliance upon
Abbot,
plaintiffs have not shown how their claimed use of the stream in the instant case, when measured by the constitutional mandate, is a reasonable one. In essence their position is that such use is a
*143
beneficial one encompassed within their riparian rights and that all beneficial uses are reasonable uses. Such a position ignores rather than observes the constitutional mandate. Article XIV, section 3, does not equate “beneficial use” with “reasonable use.” Indeed the amendment in plain terms emphasizes that water must be conserved in California “with a view of the reasonable
and
beneficial use thereof in the interest of the people,” that the right to use water “shall be
limited
to such water as shall be
reasonably
required for the beneficial use to be served,” and that riparian rights “attach to, but to
no more than
so much of the flow” as may be required “in view of such reasonable
and
beneficial uses.” (Italics added.) (Cal. Const., art. XIV, § 3; see fn. 5,
ante.)
Thus the mere fact that a use may be beneficial to a riparian’s lands is not sufficient if the use is not also reasonable within the meaning of section 3 of article XIV and, as indicated, plaintiffs’ use must be deemed unreasonable. Anything to the contrary in
Los Angeles County Flood Control Dist.
v.
Abbot, supra,
Assuming arguendo the unreasonableness of their use of the stream, plaintiffs contend that in any event they are entitled to be compensated for the damage to their property interests. Article XIV, section 3, they say, was only a procedural as opposed to a substantive change in the law and had the effect of merely denying injunctive relief to protect certain riparian uses. Article I, section 14, 10 on the other hand confers on them a cause of action for money damages for the injury to their real property resulting from the district’s public improvement.
While plaintiffs correctly argue that a property right cannot be taken or damaged without just compensation, they ignore the necessity of first establishing the legal existence of a compensable property interest. Such an interest consists in their right to the
reasonable
use of the flow of the water. Their riparian rights attach to no more of the flow of the stream than that which is required for such use. (Cal. Const., art. XIV, § 3; see fn. 5,
ante.)
As we said in
Ivanhoe Irr. Dist.
v.
All Parties, supra,
Moreover plaintiffs’ claim to money damages under the circumstances of the instant case is foreclosed by the decision of this court in
Gin S. Chow
v.
City of Santa Barbara, supra,
In discussing the limitation of reasonable use of natural waters as a reasonable exercise of the police power, the court continued: ‘ ‘ There is nothing novel about the limitation of the riparian right to a reasonable, beneficial use of water. *145 Other western states which first adopted the common-law doctrine of riparian rights have effectually changed it to meet modern conditions. ... A general survey . . . discloses that whenever the riparian right has been deemed a vested right such right has become defined to be, or limited to, the right of the riparian owner to make a reasonable . . . use of water. Although the riparian right in this state has not heretofore been so defined and limited, a limitation of the right as thus defined has now become the law of this state whenever, under situations of fact calling for its proper exercise in behalf of the people of the state, the doctrine of police power may be applied. The present case presents such a situation of fact, and the eminent domain provisions of the Constitution have no application.” (217 Cal. atpp. 704-705.)
From the foregoing we arrive at the conclusion that since there was and is no property right in an unreasonable use. there has been no taking or damaging of property by the deprivation of such use and, accordingly, the deprivation is not compensable. (See
Peabody
v.
City of Vallejo, supra.
Plaintiffs direct our attention to
United States
v.
Gerlach Live Stock Co.
(1950)
Gerlach,
of course, is distinguishable from the instant case in that plaintiffs here are not making a use of the natural flow of waters which can be deemed reasonable, and it was on the determination of a reasonable use that
Gerlach
turned: ' ‘ Any hazard to claimants’ rights lurks in the following clause: ‘and such right does not and shall not extend to the waste or unreasonable use or unreasonable method of use or unreasonable method of diversion of water.’ Since riparian rights attach to, and only to, so much of the flow of the San Joaquin as may be put to beneficial use consistently with this clause, claimants can enforce no use of wasteful or unreasonable.
*146
character.” (
Our foregoing conclusion disposes of plaintiffs’ contention that they have a right to recover damages under section 1245 of the Water Code. As we have explained, since there was and is no property right in the instant unreasonable use, there has been no taking or damaging of property. Since by constitutional fiat no property right exists, none is created by statutory provisions intended to provide compensation for the deprivation of protectible property interests. Thus plaintiffs’ reliance upon section 1245 which imposes liability upon municipal entities for damage caused to any “property, business, trade, profession or occupation” by the municipality’s entry into a watershed “for the purpose of acquiring or increasing a water supply” is misplaced for the reason that there is no damaging of any property interest to which plaintiffs have a lawful right.
Finally, having in mind these legal principles and the conclusions which we have reached, we turn to inquire whether the judgment properly rests upon them under the rules governing the summary judgment procedure (Code Civ. Proc., § 437c)
11
invoked by defendant.
12
We have summarized these well-settled rules as follows: " The matter to be determined by the trial court in considering such a motion is whether the defendant (or the plaintiff) has presented any facts which give rise to a triable issue. The court may not pass upon the issue itself. Summary judgment is proper only if the affidavits in support of the moving party would be sufficient
*147
to sustain a judgment in his favor and his opponent does not by affidavit show such facts as may be deemed by the judge hearing the motion sufficient to present a triable issue. The aim of the procedure is to discover, through the media of affidavits, whether the parties possess evidence requiring the weighing procedures of a trial. In examining the sufficiency of affidavits filed in connection with the motion, the affidavits of the moving party are strictly construed and those of his opponent liberally construed, and doubts as to the propriety of granting the motion should be resolved in favor of the party' opposing the motion. Such summary procedure is drastic and should be used with caution so that it does not become a substitute for the open trial method of determining facts."’
(Stationers Corp.
v.
Dun & Bradstreet, Inc.
(1965)
Addressing ourselves first to the sole affidavit filed in support of defendant's motion, the matters alleged therein tend to establish but one material fact—that defendant is a proper appropriator of the waters of Nicasio Creek. Thus the affidavit, primarily because it neglects to delineate the nature and relationship of the plaintiffs' property interest claimed to have been damaged by defendant’s appropriation of the water, at first blush appears to fail in establishing that the “action has no merit,” or that defendant is entitled “to a judgment in the action.” (Code Civ. Proe., § 437c.)
Where a plaintiff moves for summary judgment, he cannot depend upon allegations in his complaint to cure deficient affidavits, but must set out in his affidavits facts in support of all elements entitling him to a recovery.
(Kimber
v.
Jones
(1954)
However the courts have heretofore recognized that a distinction exists where the party seeks to rely on his
adversary’s
rather than his
own
pleadings to establish facts not contained in his affidavit. (See Civil Procedure Before Trial (Cont. Ed. Bar), Summary Judgments, p. 868.) A moving plaintiff may, for instance, rely upon a defendant’s admission of a material allegation contained in the complaint.
(Schulze
v.
Schulze
(1953)
The court in
Gardenswartz
reasoned that those pleading matters which were before the court and would be foreclosed on a trial of the issues could be considered on the motion for summary judgment. This follows from the principle that the aim of the procedure embodied in section 437c is to discover, through the media of affidavits, whether there are triable issues of fact.
(Stationers Corp.
v.
Dun & Bradstreet, Inc., supra,
The foregoing makes it clear that a moving defendant, unlike a moving plaintiff, need merely establish a defense to a claim theretofore asserted “in the action.” His supporting *149 affidavits are responsive in nature and are necessarily addressed to the complaint. It is within the contemplation of section 437c that the factual matters which he sets out in such affidavits are to take their significance upon a consideration of the complaint. In no way departing from the rule that such affidavits are to be strictly construed, it would nevertheless be placing form before substance if we were to require that a moving defendant’s affidavits which assert facts establishing a defense when considered with the particular claim relied upon by plaintiff:, must be deemed insufficient because they further fail to repeat therein those matters already asserted in the complaint. In such a case, the repetition of the substance of the complaint would be a useless act, the doing of which the law does not require. (Civ. Code, § 3532.)
When defendant’s affidavit is considered in context with plaintiffs’ complaint it is immediately apparent, for reasons heretofore enunciated, that the unreasonable use of the waters of Nicasio Creek relied upon by plaintiffs as purported riparians, does not constitute a compensable property right when deprived by defendant’s lawful appropriation of such waters. Defendant’s affidavit, accordingly, is sufficient to sustain the judgment. Should plaintiffs’ counteraffidavit nevertheless raise triable issues of fact, we could not affirm the judgment.

Hibernia Bank, supra,

The minute order granting said motion also states: "It is therefore not necessary to determine whether the claim was timely filed, although it is the Court’s incidental opinion that it was; nor is it necessary to determine whether plaintiffs’ failure to participate in the administrative proceedings would bar their claim, although it is the Court’s incidental opinion that it would not if vested substantive riparian rights were involved. ’ ’

Haggin, supra,
this court said:
“By the common law the right of the riparian proprietor to the flow of the stream is inseparably annexed to the soil, and passes with it, not as an easement or appurtenance, blit as part and parcel of it. Use does not create the right, and disuse cannot destroy or suspend it. The right in each extends to the natural and usual flow of all the water, unless where the quantity has been diminished as a consequence of the reasonable application of it by other riparian owners for purposes hereafter to be mentioned.”
(
It is noteworthy that while this court in
Lux
v.
Haggin, supra,
The amendment has not since been modified, altered or changed, and provides: “ It is hereby declared that because of the conditions prevailing in this State the general welfare requires that the water resources of the State be put to beneficial use to the fullest extent of which they are capable, and that the waste or unreasonable use or unreasonable method of use of water be prevented, and that the conservation of such waters is to be exercised with a view to the reasonable and beneficial use thereof in the interest of the people and for the public welfare. The right to water or to the use or flow of water in or from any natural stream or water course in this State is and shall be limited to such water as shall be reasonably required for the beneficial use to be served, and such right does not and shall not extend to the waste or unreasonable use or unreasonable method of use or unreasonable method of diversion of water. Riparian rights in a stream or water course attach to, but to no more than *138 so much of the flow thereof as may be required or used consistently with this section, for the purposes for which such lands are, or may be. made adaptable, in view of such reasonable and beneficial uses; provided, however, that nothing herein contained shall be construed as depriving any riparian owner of the reasonable use of water of the stream to which his land is riparian under reasonable methods of diversion and use, or of depriving any appropriator of water to which he is lawfully entitled. This section shall be self-executing, and the Legislature may also enact laws in the furtherance of the policy in this section contained. ’ ’
For example "as between riparian owners
(Pabst
v.
Finmand,
In
Lindsay-Strathmore
it was said: “Under this new doctrine, it is clear that when a riparian or overlying owner brings an action against an appropriator, it is no longer sufficient to find that the plaintiffs in such action are riparian or overlying owners, and, on the basis of such finding, issue the injunction. It is now necessary for the trial court to determine whether such owners, considering all the needs of those in the particular water field, are putting the waters to any reasonable beneficial uses, giving consideration to all factors involved, including reasonable methods of use and reasonable methods of diversion. From a consideration of such uses, the trial court must then determine whether there is a surplus in the water field subject to appropriation.

Gin S. Chow
v.
City of Santa Barbara, supra,
Cal. Const., art. I, § 14, provides in pertinent part: "Private property shall not be taken or damaged for public use without just compensation ...”
Section 437c provides in part: "In superior courts and municipal courts if it is claimed the action has no merit, or that there is no defense to the action, on motion of either party, after notice of the time and place thereof in writing served on the other party at least 10 days bef ore such motion, supported by affidavit of any person or persons having knowledge of the facts, the answer may be stricken out or the complaint may be dismissed and judgment may be entered, in the discretion of the court unless the other party, by affidavit or affidavits shall show such facts as may be deemed by the judge hearing the motion sufficient to present a triable issue of fact. ...”
All parties before us ignore these rules. Plaintiffs in particular seem to misconceive the issue actually presented for our review and, instead of asserting the insufficiency of defendant’s affidavit to support the judgment or the sufficiency of their own affidavit to raise a triable issue, advance various contentions as to the sufficiency of their complaint to state a cause of action.
