Mr. Chief Justice Moore

delivered the opinion.

The question to be considered is whether or not it was necessary, as a condition precedent to the assertion of the right sought to be invoked, to allege in the complaint that plaintiff was the sole owner of all the land bordering on both sides of Catherine Creek, from the. head gate of the proposed ditch to the lower terminus thereof, or had secured from the riparian proprietors on that stream the exclusive right to divert and use the surplus waters thereof. A general statement of some of the. provisions of the statute ;on which this action is based, so far as they relate to the power of a corporation to condemn rights of way for ditches, and to appropriate the surplus water of a nonnavigable stream, is deemed essential to a proper understanding of the inquiry involved.

1. The use of water of streams in this State for the purpose of furnishing electrical power for all purposes is declared to be beneficial and a public necessity, and the right to divert unappropriated water therefrom for such use is granted: B. & C. Comp. § 5022. All corporations having title or possessory right to any land shall be entitled to the use and enjoyment of the water of any stream within the State, to furnish electrical power for any purposes, “so that such use of the same does not materially affect or impair the rights of prior appropriations”: B. & C. Comp. § 5023. All such corporations may appropriate and divert such waters, and may condemn rights of way for ditches for carrying the same, and may condemn the rights of riparian proprietors upon the stream from which such appropriation is made, upon complying with the terms of this act: B. & C. Comp. § 5024. Such corporations may enter upon any land for the purpose of locating a point of diversion of the water intended to be appropriated, and upon any land lying between such point and the lower terminus of its proposed ditch, for the purpose of examining the same, and of locating and surveying the line of such *246ditch: B. & C. Comp. § 5035. When the point of diversion shall have been selected, such appropriator shall post in a conspicuous place thereat a notice in writing containing a statement of the name of the ditch and of the owner thereof, the point at which its head gate is proposed to be constructed, a general description of the course of said ditch, the size or dimensions of the same in width and depth, the number of cubic inches of water (by miner’s measurement under a six-inch pressure) intended to be appropriated : B. & C. Comp. § 5036. Within 10 days from the date of posting such notice, such appropriator shall file, for record in the office of the. county clerk or recorder of conveyances, as the case may be, of the county in which said ditch is situated, a similar notice, and at the same time shall file a map showing the general route of said ditch: B. & C. Comp. § 5037. When such corporation shall have acquired the right to appropriate the water “in the manner hereinbefore provided,” it may proceed to condemn lands and premises necessary for right of way for its ditch, not .exceeding 50 feet.in width: B. & 0.' Comp. § 5038. Whenever any corporation “authorized as hereinbefore provided to appropriate water and to construct and maintain a ditch,” or to furnish electrical power for any purpose, and to condemn lands for right of way, is unable to agree with the owner of such lands as to compensation to be paid therefor, such corporation may maintain an action in the circuit court of the county in which the lands sought to be appropriated are situated, for the purpose of having such lands appropriated to its use, and for determining the. compensation to be paid to such owner therefor. The proceedings in such action, to final determination, shall be the same as those prescribed in Chapter 3 of Title 41: B. & C. Comp. § 5039. Such corporation may also maintain an action for the condemnation and appropriation of the right to the flow of water in any stream from which it proposes to divert water below the point of diversion, vested in the owners of lands lying contiguous to such stream by virtue of their location: B. & C. Comp. § 5030.

An examination of the statute, the substance of which has been stated, shows that the legislature has given corporations organized to furnish electrical power for all purposes authority to condemn *247the rights of riparian proprietors in and to the flow of the surplus water in the channel of a stream, and also the right to condemn such lands as may be needed for ditches therefrom. It is argued in support of the judgment herein that the compensation required to be paid to the several riparian proprietors for their rights in and to such surplus water may be so great as utterly to defeat the furnishing of electrical power, thereby demonstrating that a condemnation of land as a right of way for a ditch is unne.ccssary, and hence no error was committed as alleged. It might be contended with equal force, in an action to condemn the diversion and appropriation of the surplus water of a stream, - that the cost of securing a right of way for a ditch in which to conduct the water might be so excessive as to exhaust the financial resources of the corporation seeking to assert the power conferred, thus thwarting the purpose for which it was organized, and for that reason the action to condemn the diversion of the surplus water should be deferred until the right of way for a ditch in which to conduct it had been secured. As the right to the uninterrupted flow of water in the channel of a stream, and the ownership of the land across which it may be necessary to construct a ditch, are not always vested in the same person, it would follow, in cases of such diverse right and ownership, if the principle insisted upon were adopted, that a condemnation of either separately could never be enforced. When a corporation organized to furnish electrical power for all purposes has selected a point for the diversion of the water of a stream, surveyed and located the line of its ditch, posted the specified notice at the place and in the manner designated, and filed within the time prescribed a similar notice for record in the proper office, together with a map showing the general route of the ditch, the right to appropriate the water is thereby acquired: B. & C. Comp. § 5038.

2. The organic law of the State, regulating the. exercise of the right of eminent domain, is, so far as applicable herein, as follows : “Private property shall not be taken for a public use * * without just compensation * * first assessed and tendered”: Const. Or. Art. I, § 18. This clause impliedly prohibits the taking of private property for a private use, though just compen*248sation be made therefor: Witham v. Osburn, 4 Or. 318 (18 Am. Rep. 287); Bridal Veil Lum. Co. v. Johnson, 25 Or. 105 (34 Pac. 1026).

3. It has been held by this court that the legislative assembly must in the first instance declare the necessity for and the expediency of an exercise of the right of eminent domain in an act conferring power for that purpose, but the question of whether or not a proposed use is in fact public or private is to be determined by the courts, independently of the objects expressed in the charter of the' corporation claiming to be the recipient of the authority, or of the statute purporting to confer it: Bridal Veil Lum. Co. v. Johnson, 30 Or. 205 (46 Pac. 790, 34 L. R. A. 368, 60 Am. St. Rep. 818); Apex Trans. Co. v. Garbade, 32 Or. 582 (52 Pac. 573, 54 Pac. 367, 882, 62 L. R. A. 513); Fanning v. Gilliland, 37 Or. 369 (61 Pac. 636, 62 Pac. 209, 82 Am. St. Rep. 758). Whether or not the employment of the water of a stream to generate electrical power for all purposes is a public or a private use need not now be determined, but may be subsequently tried. Nor is it necessary at this time to inquire whether or not a mere legislative fiat can deprive riparian proprietors of the right which they enjoy under the rules of the common law — to have the water of a stream flow in the channel thereof, undiminished in quantity. It would seem, however, that as authority had been granted to condemn land for a ditch, and also power conferred to condemn the right to have the water of a stream flow in the channel thereof below the point of diversion, the legislative assembly had not intended to deprive or even abridge the rights of a riparian proprietor.

4. Condemnation proceedings are purely statutory, and every condition prerequisite to an exercise of the right must be strictly pursued: Oregonian Ry. Co. v. Hill, 9 Or. 377; Huddleston v. Eugene, 34 Or. 343 (55 Pac. 868, 43 L. R. A. 440, 1 Mimic. Corp. Cas. 334). The clause, “When such * * corporation shall have acquired the right to appropriate water in the manner here- ■ inbefore provided” (B. & C. Comp. § 5028), evidently means, by considering the entire context of the act, that, by a strict compliance with the preceding provisions of the statute, a right to institute an action to condemn the use of water to which a *249riparian proprietor is entitled was thereby initiated, and, for the purpose of cutting off intervening rights, relates back to the date of posting the notice: B. & C. Comp. § 5031. If the phrase “in the manner hereinbefore provided” had been omitted from Section 5028, B. & C. Comp., it is quite probable that an action to condemn land for a ditch could not be maintained until the right to divert the surplus water of a stream had been secured.

It will be observed that the phrase quoted refers to the preceding sections of the act, upon a strict compliance with which the right to appropriate water is acquired. The word “appropriate,” in the arid region of the United States, is generally understood to mean an application of water to a beneficial use; but, in the section of the statute to which attention is called, the word under consideration cannot be so construed, where the rights of riparian proprietors have attached to a stream. If a corporation organized to generate electrical power for all purposes was the sole riparian proprietor on a stream, a strict compliance by it with the provisions of Sections 5026,' 5027, B. & C. Comp., would probably confer upon it the right to appropriate all the water flowing in the channel, and authorize the maintenance of an action to condemn a right of way for a ditch in which to conduct the water across the lands of other persons. In case such corporation owned all the land bordering on a stream between the point of diversion and the lower terminus of its proposed ditch, the word “appropriate.” might probably be used in its ordinary acceptation. That the legislative assembly intended it should receive such meaning only in case the plaintiff in an action to condemn a right of way for a ditch was the sole riparian proprietor to be affected by the diversion of water from a stream, is evident from the fact that Section 5030, B. & C. Comp., authorizes the maintenance of an action to condemn the rights of the bank owners between the points of diversion and the lower terminus of the. proposed ditch. ■ To hold otherwise would in some instances defeat the very purposes sought to be subserved by the passage of the act, a fair construction of which in its entirety authorizes, in our opinion, the maintenance of an action either to condemn land for a ditch, or to condemn the right to have the water flow in the channel of a stream through the prem*250ises of a riparian proprietor, or both, rights may be joined in one action when vested in the same defendant, as a plaintiff may elect. An examination of Section 5030, B. & C. Comp., will show that in the passage of the act, or in the enrollment, the mode to be pursued in condemning the rights of riparian proprietors is wholly omitted. Whether or not such omission will defeat plaintiff’s right to divert the surplus water of Catherine Creek, so far as defendants’ interest therein may be involved, need not now be determined, believing, as we do, that this action can be maintained to condemn land for the ditch.

It follows from these considerations that the judgment is reversed, and the cause remanded, with directions to overrule the demurrer, and for such further proceedings as may be necessary, not inconsistent with this opinion. Reversed.
