The State took possession of and here asks condemnation of 19 acres on which were located some trees, buildings, a spring, two 'shallow wells, and four dams. After a jury verdict of $8,750 for land taken and damages to the remainder of the original tract of 154 acres the State appeals. The main question presented is whether the trial court erred in refusing to give the State's requested Instruction I A on a landowner's duty to minimize damages.
The testimony on behalf of defendants of the before and after taking values was all based on the fact that the tract had a source of water supply necessary to graze livestock before the taking and none thereafter. The water in the dams was mainly from the wells in the land taken. It appears this land *313is in an area where rainfall is deficient and the importance of a supply of water may be summed up in the words of one witness that "You haven't much if you haven't got water" and another that water was like gold. After this evidence was admitted the State introduced evidence that new wells could be dug on the remaining land at a cost of $350, that in fact test holes had been dug which would produce a sufficient amount of water for such livestock.
Plaintiff's proposed Instruction I A, which the court refused to give was:
"The landowner has a duty to minimize his damages and to use all reasonable exertion and steps to protect himself, and avert, as far as practicable, the injurious consequences of the taking. However, any expenses which the landowner reasonably and in good faith incurs in an effort to minimize his loss, are to be taken into account in computing the compensation to be awarded him."
We conclude the court erred in so ruling as the instruction was a correct statement of the law and was based on the described testimony in behalf of the State which the court had properly admitted in evidence. State Highway Commission v. Hayes Estate, 82 S.D. 27, 140 N.W.2d 680, approved the admission in evidence of costs claimed necessary to restore the property to its condition before the taking, where the court wrote:
"As a general rule, in determining the diminution in market value of the land not taken, it is proper to take into consideration the expense made necessary by the improvement, 29A C.J.S. Eminent Domain § 164, in order to restore the land to its most advantageous use, 18 Am.Jur., Eminent Domain, § 269, or in adjusting it to the changed conditions brought about by the taking."
The court then quoted from Pima County v. De Concini, 79 Ariz. 154, 285 P.2d 609:
*314" 'The rule also is that in arriving at the market value of land which has been damaged by the exercise of the right of eminent domain the court has a right to admit evidence of possible expenditures which, if expended, would diminish the damages.' "
The admission of such evidence and argument to the jury thereon would be of little avail to a party without an instruction as to its effect.1 These expenditures, while admissible and proper to be considered by the jury in determining the diminution in the market value of the land not taken, must not exceed the difference in market value before and after the taking. However, as said in State Highway Commission v. Hayes Estate, supra, that would not occur in the instant case. This guide fulfills the purpose of just compensation by restoring owners to as good a position as they were in prior to the taking. State Highway Commission v. Fortune, 77 S.D. 302, 91 N.W.2d 675, 77 A.L.R.2d 533, and State Highway Commission v. American Memorial Parks, Inc., 82 S.D. 231, 144 N.W.2d 25.
In City and County of Denver v. Noble, 1951, 124 Colo. 392, 237 P.2d 637, plaintiff claimed defendant, in building a road, damaged and destroyed an irrigation ditch used for conveying water to her property. The jury awarded $9,000 damages though there was evidence the owner could obtain the water by lowering a culvert at an expense of about $200. The court reversed because of inconsistent and contrary instructions. Approving one of the instructions stating it was her duty " 'to take all reasonable steps necessary to mitigate the damages'" it wrote:
"It was the duty of plaintiff to mitigate her damages, if she could reasonably do so, by constructing another ditch or lateral to convey water to her land."
The Court of Appeals of New York reached a similar conclusion as to the duty to minimize damages by drilling a well *315in Mayes Company v. State, 1966, 18 N.Y.2d 549, 277 N.Y.S.2d 393, 223 N.E.2d 881. The Court of Claims had allowed claimant $200,000 for loss of water caused by a road being built over a spring and portion of a pond. This award was based on the annual cost of buying water from the public supply of a village over a 20-year period. There was evidence a well could be drilled on claimant's property for around $14,000 which would produce sufficient water. The court first rejected a contention this involved "too much speculation * * * to justify the expense" and then said:
"As Judge Selden observed long ago, there rests on a party seeking damage 'the active duty of making reasonable exertions to render the injury as light as possible' * * •
"Nevertheless, the party seeking damages is under the duty to make a 'reasonable effort' to avoid consequences of the act complained of * * * It is, indeed, a rule of broad acceptance that 'No recovery may be had for losses which the person injured might have prevented by reasonable efforts and expenditures' (25 C.J.S. Damages § 33, p. 698; see, also, 29A C.J.S. Eminent Domain § 155, p. 655)."
Accord as to duty to build a ford, Little v. Burleigh County, 1957, N.D., 82 N.W.2d 603. The above opinions apply what seems to be the general rule to specific fact situations comparable to the case at bar.2
Perhaps it should be added that "mitigation of damages" is well recognized in the general law on that subject. 22 Am. Jur.2d, Damages, § 200 et seq. There and in § 30 through § 33 the phrase is said to be one of the limitations on the amount of recovery; it may be stated that a party may not recover damages which he could reasonably have avoided. The cited text denominates these efforts to minimize damages more precisely *316as the doctrine of avoidable consequences and that often it is expressed as a duty of a party to minimize his damages or as an obligation to take reasonable action to avoid enhancing the damages.
"Such statements are inaccurate expressions of the doctrine * * * because * * * the failure to take reasonable action to limit damages creates no affirmative right in anyone. The only result of such a failure is that the court will not allow damages for those consequences of the injury which it believes the plaintiff could reasonably have avoided." 22 Am.Jur.2d, Damages, § 30.
It is probably an exercise in semantics to discuss the niceties of the word "duty" in the requested instruction. In an early work, Sutherland on Damages, Fourth Ed. §§ 88 and 90, uses the word "duty". South Dakota Pattern Jury Instruction 33.02 under the title "Damages—Property—Duty to Mitigate", states the owner of the damaged property "must exercise ordinary care to minimize" existing, and to prevent further, damages; the California Jury Instructions, BAJI (5th Ed.) No. 14.68 under the title "Duty to Mitigate" states the owner "is bound to * * * minimize the damages" while as to personal injuries in No. 14.67 it states it is his "duty" to do so. The word "duty" likewise is used in 7 Am.Jur., Pl. and Pr. Forms, Damages, 7:86. In 15 Am.Jur., Damages, § 27, the title is "Duty to Prevent or Minimize Damages" while the text states "One who is injured * * * is bound to exercise reasonable care and diligence to avoid loss or to minimize or lessen the resulting damage". (Emphasis supplied) Section 40 thereof uses the term "duty" in the text. To § 27 is ap-pended note 12 from, which this court quoted in Chicago, Burlington & Quincy Railroad Company v. Wheaton, 76 .S.D. 467, 80 N.W.2d 868, approving the rule in principle. In that note will be found citations and quotations from cases using the various terms mentioned, all are in effect of the same meaning. It appears this note led to the text in 22 Am.Jur.2d, Damages, §§ 30 - 32, supra. It is clear that if a person must or is bound to do an act, it is a duty to do so.
*317Two decisions of the North Dakota Supreme Court discuss this subject. In the first opinion, Nicola v. Meisner, 1957, N.D., 84 N.W.2d 702, the court quoted Sections 27 and 40 of 15 Am.Jur., Damages, and from Michigan and Nebraska opinions which used the term "duty". Thereafter in Stetson v. Investor's Oil, Inc., 1966, N.D., 140 N.W.2d 349, the court compared an instruction given with No. 19 refused. It wrote:
"The court's instruction sets forth a statement of the general rule relating to the duty to minimize damages, or, as it is sometimes called, the doctrine of avoidable consequences. Investors' requested instruction No. 19 states another version of the same general rule. This court has approved the language used by the trial court in its instruction and has also approved the language used by Investors in its requested instruction No. 19. Nicola v. Meisner, N.D., 84 N.W.2d 702, 705. The language in Nicola states the rule substantially as found in the court's instruction and then states another version of the same rule which is substantially the language used in Investors' requested instruction No. 19. The Nicola case recognized that the version of the rule found in Investors' requested instruction No. 19 is only another statement of the same rule found in the trial court's instruction. The trial court did not err in choosing one version of the rule and rejecting the other when both versions were equivalent."
It is not necessary to decide if a "duty" version or an "avoidable consequences" version should have been given. The requested instruction was proper and it or an equivalent should have been given.
The Colorado, Arizona and New York Courts and this court in State Highway Commission v. Hayes Estate, supra, did apply the doctrine to condemnation proceedings in the cited cases, and we add the California Supreme Court in Albers v. County of Los Angeles, 62 Cal.2d 250, 42 Cal.Rptr. 89, 398 P.2d 129, *318expressly discussed the doctrine and applied it to allow added compensation for the efforts made. This case does not involve that issue and we express no opinion as to it.
Some argument is made that mitigation of damages was not in issue as it was not pleaded, citing SDCL 1967, 31-19-23 (6) in support. That provision requires, among other things, the declaration of taking shall contain:
"(6) Any prior written memoranda or agreement, right of way plans and specifications for the proposed highway, setting forth in detail the access roads, underpasses, overpasses, drainage facilities, and other features as pertain to the adjacent landowner's access to, and means of crossing over and under the proposed highway, together with a description of any additional factors which the state intends to rely upon in mitigation of damages."
This statute requires the proposed construction plans show items of a class similar to those set forth in detail therein so as to advise the owner of the effect the taking will have on his land and its general relationship to access, etc. It does not refer to matters in rebuttal of claims for damages made by the owner such as loss of wells, dams, etc., which will be lost by the taking and were clearly evident therefrom.
The court therefore erred in refusing the requested instruction and the judgment must be and it is reversed.
RENTTO and HOMEYER, JJ„ concur. HANSON, J„ dissents. ROBERTS, J., concurs in dissent.. The trial court gave such an instruction in State Highway Commission v. Hayes Estate, supra, which this court said was “complete and accurate”.
