Municipal corporations have the right of eminent domain for the purpose of acquiring private property to construct and maintain a municipal water system. G.S. 40-2(2). The procedure *321applicable to the condemnation proceeding now under consideration is that prescribed by G.S. Chapter 40, “Eminent Domain,” Article 2, “Condemnation Proceedings,” G.S. 40-11 et seq. Under this procedure, after the filing of the petition and answer, commissioners are appointed to appraise the subject property. G.S. 40-12; G.S. 40-16; G.S. 40-17. If the condemnor, “at the time of the appraisal, shall pay into court the sum appraised by the commissioners, then and in that event the said [condemnor] may enter, take possession of, and hold said lands, notwithstanding the pendency of the appeal, and until the final judgment rendered on said appeal.” G.S. 40-19. “The title of the landowner is not divested unless and until the condemnor obtains a final judgment in his favor and pays to the landowner the amount of the damages fixed by such final judgment. G.S. 40-19; Light Co. v. Manufacturing Co., 209 N.C. 560, 184 S.E. 48.” Topping v. Board of Education, 249 N.C. 291, 299, 106 S.E. 2d 502, 508 (1959). [Note: The alternative provisions for condemnation by municipal corporations enacted by Chapter 698, Session Laws of 1971, now G.S. 160A-240 et seq., are not applicable to proceedings pending on 1 January 1972.]
The procedure prescribed by G.S. 40-11 et seq. was applicable to condemnation proceedings instituted by the State Highway Commission prior to 1 July 1960. The procedure presently applicable to condemnation proceedings by the State Highway Commission is prescribed by the 1959 statutes now codified in G.S. Chapter 136, “Roads and Highways,” Article 9, “Condemnation,” G.S. 136-103 et seq. Under these statutes, title and immediate right to possession are vested in the State Highway Commission upon the filing of the complaint, the declaration of taking, and the deposit in court of the amount of the estimated compensation stated in the declaration. G.S. 136-104. Highway Commission v. Industrial Center, 263 N.C. 230, 139 S.E. 2d 253 (1964). This change in the law must be kept in mind when considering decisions involving the exercise of the right of eminent domain by the State Highway Commission.
When the Highway Commission exercises its right of eminent domain in accordance with G.S. 136-103 et seq., “the right to compensation rests in the person who owned the land immediately prior to the filing of the complaint and declaration of taking. He has nothing he can sell pending ascertainment of fair compensation. Formerly, since his title was not divested until compensation was paid, he could sell, G.S. 40-26. The per*322son who owned when the award was confirmed was the person to be compensated. Liverman v. R. R., 109 N.C. 52, 13 S.E. 734. The Highway Commission, when it files its complaint, must file a memorandum of its action with the register of deeds where the land lies, G.S. 136-104. This has the same effect as a conveyance of the property.” Highway Commission v. Industrial Center, supra, at 232, 139 S.E. 2d at 255.
In a condemnation proceeding under G.S. 40-11 et seq., ordinarily, “for the purpose of determining the sum to be paid as compensation for land taken under the right of eminent domain, the value of the land taken should be ascertained as of the date of the taking, and . . . the land is taken within the meaning of this principle when the proceeding is begun.” Power Co. v. Hayes, 193 N.C. 104, 107, 136 S.E. 353, 354 (1927); Ayden v. Lancaster, 197 N.C. 556, 559, 150 S.E. 40, 42 (1929); Charlotte v. Spratt, 263 N.C. 656, 662, 140 S.E. 2d 341, 345 (1965).
[1] Although the value of the land is to be determined as of the date the condemnation proceeding is commenced, much time may elapse from this date until the condemnor obtains the right to possession and a final judgment. The condemnor acquires no right to possession until it pays into court the value of the subject property as determined by the appraisers; it acquires no title to the property until it obtains a final judgment and pays to the landowner the amount of compensation fixed by such judgment. The principal amount of the judgment is the value of the subject property as of the date the special proceeding is commenced as finally determined by jury verdict or otherwise, whether more or less than the valuation placed thereon by the commissioners, with interest thereon from the date the condemnor acquired the right to possession thereof by payment into court of the amount of the valuation as fixed by the appraisers. Winston-Salem v. Wells, 249 N.C. 148, 105 S.E. 2d 435 (1958); Light Co. v. Briggs, 268 N.C. 158, 150 S.E. 2d 16 (1966).
In Winston-Salem v. Wells, supra, the proceeding was instituted on 8 February 1956; the amount fixed by the appraisers was paid into court on 30 March 1956; and the court held that the landowner was entitled to interest from 30 March 1956 on the value of the property as determined in the superior court. In Light Co. v. Briggs, supra, the condemnation proceeding was instituted on 2 April 1962; the amount of the damages *323assessed by the commissioners was paid into court on 8 June 1962; and the landowners were held entitled to interest from 8 June 1962 on the value of the property as determined in the superior court.
[2] The cited decisions recognize the landowner’s right to continue in possession of his property from the commencement of the special proceeding until the payment into court by the condemnor of the value of the property as determined by the commissioners. Until such payment is made, the landowner may sell the subject property; however, the special proceeding constitutes a Us pendens, giving notice to the purchaser that he succeeds to the status of the seller in the pending proceeding. G.S. 40-26; Caveness v. R. R., 172 N.C. 305, 90 S.E. 244 (1916); Hughes v. Hwy. Comm. & Oil Co. v. Hwy. Comm. & Equip. Co. v. Hwy. Comm., 275 N.C. 121, 165 S.E. 2d 321 (1969). Too, when the date for the attachment of the lien for taxes falls within this period, the landowner is obligated to list the subject property and pay the taxes thereon for such year or years. Lumber Co. v. Graham County, 214 N.C. 167, 198 S.E. 843 (1938). Without undertaking to define the limits upon the landowner’s right to use the subject property during this period, it is clear that, absent unusual circumstances, he may continue to use it to the same extent and in the same manner in which he had been using it prior to the commencement of the condemnation proceeding. Hence, if the Goforths had planted crops on bottom lands referred to in the cross-complaint in the years prior to the commencement of the condemnation proceeding, they had the right to plant, cultivate and harvest crops on the bottom land until such time as their right to possession was terminated by the payment into court by Kings Mountain of the amount of the value of the subject property as determined by the commissioners.
The record contains a notation that the petition in the condemnation proceeding was filed 3 September 1969. It is silent as to all subsequent events in that proceeding except the portion of the Goforth pleading which relates solely to the allegations of the petition. Thus, the record does not disclose (1) when commissioners were appointed; (2) when Kings Mountain paid into court the amount of the commissioners’ appraisal; (3) the value of the subject property as of 3 September 1969 as determined by the jury, and the court’s instructions with reference thereto; and (4) the date and amount of the judgment *324in the condemnation proceeding, including the date from which it provides for interest on the principal sum.
From the record, and from statements on oral argument, we infer that the crops referred to in the Goforth cross-complaint were planted and flooded during the period between the filing of the petition and the payment of the value of the Goforth property as determined by the commissioners. If so, the Goforths then had possession as a matter of right. Of course, absent special circumstances, the Goforths would not be entitled to recover if the crops were planted and flooded at a time when they had no legal right to the possession of the land.
Further consideration is upon the assumption that the Go-forths had the legal right to the possession of the lands when the crops were planted and flooded, and that they have not been compensated by interest from the date the proceeding was instituted or otherwise for the period preceding the payment into court of the value of their property as fixed by the commissioners.
The burden of proof rests upon the Goforths to establish the liability of Kings Mountain and the amount of their damages. The question before us is whether the evidence, when considered in the light most favorable to the Goforths, was sufficient to withstand Kings Mountain’s motion for a directed verdict. Kelly v. Harvester Co., 278 N.C. 153, 157, 179 S.E. 2d 396, 397 (1971).
The applicable legal principles are as follows:
[3] “[A] lower owner cannot obstruct a surface stream of water, so as to prevent the water from flowing as it naturally would, and thereby flood the lands and buildings above him, and if he does so, he incurs liability for the damage done by such flooding.” Jones v. Loan Association, 252 N.C. 626, 636, 114 S.E. 2d 638, 645 (1960), and cases cited.
“The surface of the earth is naturally uneven, with inequality of elevation. The upper and lower holdings are taken with a knowledge of these natural conditions, and the privilege or easement of the upper tenant to carry off the surface water in its natural course, under reasonable limitations, and the sub-serviency of the lower tenant to this easement are the natural incidents to the ownership of the soil. The lower surface is doomed by nature to bear this servitude to the superior and must receive the water that falls on and flows from the latter.” Miz *325 ell v. McGowan, 120 N.C. 134, 137, 26 S.E. 783, 784 (1897). The servient tenant “cannot set up a barrier to the flow of the water in its natural or accustomed channel if it will result in injury to his neighbors.” Clark v. Guano Co., 144 N.C. 64, 77, 56 S.E. 858, 863 (1907). Since the respective rights of the upper and lower proprietors are property rights, the invasion thereof, not negligence, affords the basis for recovery. Braswell v. Highway Commission, 250 N.C. 508, 108 S.E. 2d 912 (1959).
[4] Ordinarily, the invasion of a property right of the upper proprietor by the lower proprietor would constitute a trespass which would entitle the aggrieved party to damages or injunctive relief or both. However, if a property right of the upper proprietor is invaded by a party that has authority to condemn this property right in the exercise of its power of eminent domain such invasion constitutes a “taking” of the landowner’s property and the action becomes in effect an action for “inverse condemnation.” See Charlotte v. Spratt, supra, and cases cited.
[5] The evidence offered by defendants Goforth was sufficient to permit the following findings: In the two instances prior to August 1970 when the 40 acres were flooded, the water subsided within a few hours and caused no material damage. Both in August 1970 and in February 1971 the crops on the 40 acres were completely under water for periods of two or three weeks. The evidence is silent as to the impact of the breaking of the Dover Mill dam four or five miles upstream from the Goforth property. In any event, the breaking of the Dover Mill dam referred only to what occurred in August 1970. There was no material difference between the extent to which the Goforth land was flooded in August 1970 and the extent to which it was flooded in February 1971. The lands along Buffalo Creek south of the dam were not flooded.
Assuming, as the record before us implies, that the Goforths were the owners and entitled to the possession of the 40 acres when the crops were planted and flooded, we hold the evidence was sufficient for submission to the jury and to withstand the motion for a directed verdict in favor of defendant.
The decisions cited in Kings Mountain’s brief are not pertinent to the present factual situation. Both Bruton v. Light Co., 217 N.C. 1, 6 S.E. 2d 822 (1940), and Bowling v. Oxford, 267 N.C. 552, 148 S.E. 2d 624 (1966), involved actions by lower riparian owners against upper riparian owners for damages on account of negligence in the construction, maintenance or *326operation of a dam. The other cited decision, Letterman v. Mica Company, 249 N.C. 769, 107 S.E. 2d 753 (1959), involved an action by an upper riparian owner on account of flooding allegedly caused by a dam maintained by a lower riparian owner. The demurrer of defendant English Mica Company was sustained on the ground that the complaint disclosed that the flooding of the plaintiff’s land had not resulted from the construction or operation of the dam but because defendant Harris Clay Company, in its mining operations upstream from plaintiff, had put excessive amounts of dirt in the stream which came down and settled in the still water impounded by the dam and thereby caused the water to back upon the land and roadway of the plaintiff.
[6] Although the Goforths in their cross-complaint assert a right to recover on the ground of negligence, the claim which they allege is “sufficiently particular to give the court and the parties notice of the transactions, occurrences, or series of transactions or occurrences, intended to be proved showing that the pleader is entitled to relief. . . .” Rule 8, Rules of Civil Procedure, G.S. 1A-1. Their evidence tends to support their allegations. If defendants Goforth are entitled to relief under their allegations and evidence, Kings Mountain was not entitled to a directed verdict because defendants Goforth named “negligence” rather than “trespass” or “inverse condemnation” as the ground on which they were entitled to recover. Paris v. Aggregates, Inc., 271 N.C. 471, 482, 157 S.E. 2d 131, 139-40 (1967). Of course, defendants Goforth would be entitled to recover damages only to the extent the flooding of the 40 acres and the damage to their crops was proximately caused by the dam then under construction by Kings Mountain.
Upon the record before us, the judgment of the court below must be and is reversed. The cause is remanded for trial consistent with legal principles stated herein. However, upon retrial the presiding judge may take into consideration pertinent facts, if any, which do not appear in the record before us, bearing upon whether (1) plaintiff was in rightful possession when the crops were planted and the land flooded, and (2) whether defendants Goforth have been compensated by interest or otherwise for the period from the date of the commencement of the condemnation proceeding until the payment into court by Kings Mountain of the valuation as determined by the commissioners.
Reversed.
