This is an appeal by the Los Angeles County Flood Control District from a judgment for the plaintiff, N. E. Youngblood, in an action for damages due to erosion of a portion of plaintiff’s residential property.
The action was commenced against the city of Los Angeles, Max Rosenberg and Sоns and the flood control district. A judgment for the defendants was entered following the granting of a motion for a nonsuit, but on an appeal that judgment was reversed as to the flood control district only, with instruction that the plaintiff be permitted to amend his complaint on retrial.
(Youngblood
v.
City of Los Angeles
(1958),
It appears that a natural watercourse, usually dry, adjoins plaintiff’s property. The complaint alleges that the defendant had constructed and maintained “a partially completed double pipe and wire revetment in said waterway” some 50 feet downstream from plaintiff’s property. It was furthеr alleged in effect and a finding was made in the following language: “It is true that during the rainfall of January 1952, and on or about January 15, 1952, the revetment which was built, man *607 aged and maintained by the defendant Los Angeles County Flood Control District became clogged with debris either in the revetment channel itself оr with debris which accumulated in front of the revetment and adjacent thereto, and as a proximate result thereof water was diverted from the natural waterway and waterflow onto plaintiff’s land, causing erosion and loss of soil; all to plaintiff’s damage in the sum of $9000.00.” No other allegations of causation, or findings thereon, were made.
The action herein is one in inverse condemnation predicated on article I, section 14 of the Constitution, which provides in part that “Private property shall not be taken
or damaged
for public use without just compensation. . . .” (Emphasis аdded.)
(Bauer
v.
County of Ventura,

The basis fоr liability in the foregoing instances is a taking or damaging for a public use by the public agency.
(Bauer
v.
County of Ventura, supra,
.
As heretofore stated, in the instant case a prior judgment was reversed on appeal, and certain language in that opinion of the appellate tribunal is relied upon as establishing that the defendant is liable herein under the pleadings and findings in the instant trial. In the first trial the plaintiff pleaded a.cause of action based on liability for the removal of a tree from the watercourse and the subsequent effect of the flood waters on plaintiff’s lands. At the close of his case plaintiff sought leave to amend his complaint to predicate liability on the diversion of the flood waters from the natural watercourse, which pleading would then conform to the proof offered by
*609
plaintiff. The denial of this motion was one of the grounds of reversаl. As to that ground the reviewing court held; “We have concluded that the removal of the tree is not the event which creates liability (if any there be) upon the Flood Control District. It plainly appears that the waters would have met and, creating a whirlpool, have eaten away plaintiff’s land if the tree had not fallen. Upon the facts disclosed by this record the district would be prima facie liable in inverse condemnation because its uncompleted revetment diverted the waters from their natural flow onto plaintiff’s land and to its damage. It is immaterial whether the construction of the revetment was negligent or the design defective or well conceived; when it directly caused damage to plaintiff’s land the district became liable. This is the doctrine of
Bauer
v.
County of Ventura, supra,
The plaintiff purported to amend his complaint to state a cause of actiоn based upon the law as stated by the District Court of Appeal in its opinion. He alleged specifically in the only allegations causally connecting conduct on the part of defendant to plaintiff’s damages:
“IV
“On or about January 15, 1952, there existed a partially completеd double pipe and wire revetment in said waterway to a point about 50 feet south of plaintiff’s property, which revetment had been engineered and constructed by the defendant Los Angeles County Flood Control District, and was managed, maintained and controlled by said defendant.
“V
“During the rains of January 1952, and on or about January 15, 1952, said revetment became clogged with debris, and as a proximate result thereof water was diverted onto plaintiff’s land, causing erosion and loss of soil, all to his damage----”
Consistent with the allegations, and as hereinbefore noted, the trial сourt found that the revetment “became clogged with debris . . . and as a proximate result thereof water was diverted from the natural waterway and waterflow onto plaintiff’s land, causing erosion and loss of soil, all to plaintiff’s damage____”
*610 It is manifest that while the applicable law and the opinion of the District Court of Appeal on the prior appeal require some connection between conduct on the part of the defendant and the plaintiff's damage, in the instant ease such connection in the amended pleading at the second trial wаs neither alleged nor found. For aught that appears it was the accumulated debris which diverted the waters, and the debris accumulated for no reason associated with the uncompleted revetment. The defendant, like a private party, would not be liable in the present circumstances for flood damage unless the uncompleted revetment diverted the waters from their natural course, or caused the debris to accumulate and thereby was responsible for the diversion of the waters. As stated, neither fact is alleged nor found to have occurred.
We cannot concede that the quoted language from the reviewing court’s prior opinion can be logically construed to impose strict liability on the defendant, so that regardless of the applicable law the instant pleadings and findings would be sufficient on a theory of the law of the case. The circumstances recited by the District Court of Appeal set the context in which the language is to be construed and neither the circumstances nor the language lend support to a theory of strict liability. Neither do the cases upon which the flood control district relies as establishing the law enunciated purport to impose a strict liability. In
Bauer
v.
County of Ventura, supra,
Defendant further contends that because damages were unliquidated interest on the judgment should not run except from the date of entry of the judgment. Civil Code, section 3287, at the time of the commencement of the action herein but prior to judgment, provided: “Every persоn who is entitled to recover damages certain, or capable of being made certain by calculation, and the right to recover which is vested in him upon a particular day, is entitled also to recover interest thereon from that day. ...” In
Heimann
v.
City of Los Angeles
(1947),
There is nothing in the amendment which is indicative of any intent on the part of the Legislature to provide a different rule for the running оf interest in inverse condemnation than in condemnation eases. The amendment would appear to enlarge, rather than to restrict the recovery of interest for a judgment creditor, to include situations where the named public agencies were judgment debtors whose liability for interest generally had not theretofore existed. (See anno., 24 A.L.R2d 928, and cases cited at p. 936.) Although section 3287 did not exist in its present form at the time of the decision in the
Heimann
ease, it is manifest from the opinion in that case that the court would have rendered the same decision whethеr or not interest generally accrued on liquidated claims against state and municipal agencies. (See, for instance, quotations at p. 759 from
Taylor
v.
Bay City St. Ry.
Co.,
The record herein contains substantial evidence which would support a finding, had one been made upon appropriate pleadings, that the uncompleted revetment diverted the flood waters from the natural watercourse to the plaintiff’s damage. For that reason it does not appear that a new trial is necessary. For the reasons hereinbefore stated the judgment is reversed and the cause remanded with directions to the court below to entertain a proper motion by plaintiff to amend his complaint to conform to the proof, and thereafter to make findings on the basis of the evidence previously presented and such additional evidence which the court for good cause may permit either party to introduce, as to whether the uncompleted revetment caused plaintiff’s damage, and to render its judgment in accordance therewith.
