been supplied, there remained a quantity which he appropriated: Simmons v. Winters, 21 Or. 35 (27 Pac. 7, 28 Am. St. Rep. 727).; Carson v. Gentner, 33 Or. 512 (52 Pac. 506, 43 L. R. A. 130); Browning v. Lewis, 39 Or. 11 (64 Pac. 304); McCall v. Porter, 42 Or. 49 (70 Pac. 820, 71 Pac. 976).

1. It will be remembered that the complaint states that plaintiff and his grantor had used the water in question more than ten years adversely to the defendant, but, as his land is situated on the stream below that of the defendant, and the testimony fails to show any recognition by the latter of his alleged right, his use has not been adverse to the defendant: North Powder M. Co. v. Coughanour, 34 Or. 9 (54 Pac. 223); Bowman v. Bowman 35 Or. 279 (57 Pac. 546).

2. So, too, the answer alleges that the water issuing from the springs on Dorothy's land was used by defendant adversely to plaintiff more than ten years prior to bringing this suit. If the water from these springs was never tributary to the stream in question, defendant's use thereof could not have been adverse to plaintiff, who, as a riparian proprietor, was never entitled thereto. The testimony shows that, though the volume of water flowing in the stream to plaintiff's premises was annually diminishing, his use thereof was undisturbed until about 1898, and, if it be conceded that the water from the springs on Dorothy's land originally formed a part of this stream, the defendant's interference therewith, not having been sufficient to enable him to invoke the statute of limitations, his use of the water could not toll the plaintiff's right thereto. This eliminates the question of adverse use by the respective parties, and confines the inquiry as follows: (1) What constitutes the waters of the stream flowing through the lands of the parties; (2) has the defendant, as a riparian proprietor, taken more than his share of the water of the stream; and, if so, (3) what damage has the plaintiff suffered in consequence thereof?

3. Considering these questions in their order, the testimony shows that one R. M. Dorothy owns the east half of section 21 in township 5 north, of range 36 cast of the Willamette Meridian,

the defendant the west half of that section, and the plaintiff, the southeast quarter and the east half of the northeast quarter of section 20 in that township and range, except, however twentynine acres from the north end of the latter land, and also one acre therefrom on which a schoolhouse has been erected; that the Walla Walla River now flows westerly through the northern part of these sections near a bluff, but prior to 1870 it ran in an old channel about 200 yards south of its present bed; that a small stream, known as "Spring Branch," is found on defendant's land, and flows southwesterly to and through plaintiff's premises, emptying into the river at a point below. This branch was probably an older channel of the river, for, during freshets in the latter stream, before the channel was changed to its present bed, the water overflowed the banks on the south and passed down Spring Branch, and, to prevent the stream from permanently following such course, plaintiff's grantor, George De Haven, and others, constructed a dam on the south bank of the river on the line of the overflow. About fifteen acres of Dorothy's land was originally a swamp, in which brush and tules grew, and where the water during the entire year stood about three feet deep; but about 1884 he drained this marsh, and discovered that it was caused by three large springs therein. It is alleged in the complaint, and the court found, that the source of Spring Branch was the springs on Dorothy's land, though defendant maintains that the fountain head of this stream is a spring on his premises, and that the water from the springs on Dorothy's land never reached Spring Branch in any channel, and, this being so, the court erred in making its finding to that effect, and in rendering the decree based thereon. Each party introduced in evidence a map on which is severally delineated the land owned by the plaintiff, by the defendant, and by Dorothy; but no survey of the stream, river, old channel, or dams ever having been made, the charts do not coincide in important particulars, and hence neither can be adopted as correct, except in so far as the representations thereon are corroborated. The plaintiff contends that the dam placed in the stream, constituting an obstruction to the flow of water from the springs on Dorothy's land to his premises,

is built in the old channel. The defendant maintains, however, that the dam complained of is placed in Spring Branch, and permits as much water to flow to plaintiff's land as passed an old dam which was supplanted by the new structure, and that Spring Branch is separate from the old channel. Whether or not Spring Branch is a part of the old channel of the Walla Walla River is of no consequence, but the identity of the dam that produced the injury of which plaintiff complains is impor

tant.

Considering whether the water from the swamp on Dorothy's land ever found its way originally into Spring Branch, we think the preponderance of the testimony shows that it flowed westward therefrom on the surface into this stream, and also northward in the same manner into the old channel. When Dorothy drained this swamp, he dug a ditch therefrom northward, and conducted water into the old channel, and also made another ditch westward from the swamp to the boundary of his land, where defendant continued the conduit north, causing the water flowing therein to be discharged into the old channel. The marsh having been reclaimed, it was ascertained that the swamp was caused by three large springs, known as No. 1, which discharges its water westward, and Nos. 2 and 3, which emit their waters northward, and all now emptying into the old channel. This change in the flow of water from spring No. 1 probably causing a scarcity, George De Haven, plaintiff's grantor, Enoch Demaris, defendant's father and predecessor in interest, and one Highby Harris, who then owned land through which Spring Branch flowed, about 1885, removed a part of the old dam, built on the bank of the old channel to prevent an overflow, and let the water issuing from these springs flow down such branch, in which, as we understand the testimony, the greater part thereof has continued to glide for more than fifteen years, until the summer of 1900, when the dam was replaced, and the water from the springs conducted in the old channel to a dam built therein, where by means of a ditch it is diverted and used in irrigating crops and an orchard growing on defendant's land.

Mr. Gould, in his work on Waters (3 ed.), § 263, in elucidating the principle that water which does not flow in a channel is not subject to the rules regulating the rights of riparian proprietors, says: "But if a well-defined natural stream empties into a swamp or lake, where all definite channel is lost, and emerges again into a well-defined channel below, it is a question of fact, dependent upon the extent of the swamp or lake, whether it is the same stream; and, if it is, the owners of land upon the lower stream have riparian rights, and an owner of land upon the stream above the swamp or lake is not entitled to divert water therefrom to their injury." In the next section the learned author, discussing this question further, says: "A stream does not cease to be a watercourse, and become mere surface water, because at a certain point it spreads over a level meadow several rods in width, and flows for a distance without defined banks before flowing again in a definite channel." In Case v. Hoffman, 84 Wis. 438 (54 N. W. 793, 20 L. R. A. 40, 36 Am. St. Rep. 937), it was held that the flowing of water upon and beneath the surface of lands between a natural lake of about sixty acres in extent, and a creek into which they discharge, constitutes a watercourse, where the flow is all in the same direction, and a part of the way along a distinct and plainly marked channel, although for some of the distance it spreads over wide reaches of marsh and swamp lands, and percolates the soil in many and most places between the lake and creek. To the same effect, see Cox v. Bernard, 39 Or. 53 (64 Pac. 860), and Mace v. Mace, 40 Or. 586 (67 Pac. 660, 68 Pac. 737).

Though there is a conflict in the testimony respecting the character of the original outlet from the swamp westward-some of the witnesses insisting that it was well-defined and others that the water flowed on the surface-we think it was in fact a watercourse emanating from the springs into a swamp of sufficient extent to render it and spring No. 1 tributary to Spring Branch. The water flowing in the outlet from the swamp northward into the old channel never originally reached Spring Branch, but when De Haven, Demaris, and Harris, by a concert of action, took out the dam, and let such water, together with that from spring

No. 1, into the branch, they thereby made these springs tributary to such stream, and subject to the rules of law applicable to riparian ownership: Cottel v. Berry, 42 Or. 593 (72 Pac. 584). In that case Mr. Justice WOLVERTON, in discussing the subject said: "It seems to be a rule of law that where owners of different parcels of land conduct water across the same in an artificial channel, and do not define their respective interests in the water, their reciprocal rights thereto are to be measured and determined as if they were riparian owners upon a natural stream." In Burk v. Simonson, 104 Ind. 173 (2 N. E. 309, 3 N. E. 826, 54 Am. Rep. 304), it was held that where a change is made in the flow of a natural watercourse, either artificially or otherwise, and riparian owners acquiesce in the new state of the stream for so long a time that new rights accrue, or may be presumed to have accrued, such acquiescence is binding, and precludes a restoration of the stream and its surroundings to their original condition. In the case at bar, we think the testimony warrants the conclusion that after defendant continued the west ditch north on his premises, so as to conduct the water from spring No. 1 into the old channel, the riparian proprietors removed a part of the old dam, permitting the water issuing from Dorothy's land to flow down Spring Branch, thereby making it tributary thereto and entitling them to a reasonable use thereof.

4. The parties being riparian proprietors, and entitled to the reasonable use of the water flowing in Spring Branch, including that issuing from the springs on Dorothy's land, the next question to be considered is whether the defendant has taken more than his share. In Jones v. Conn, 39 Or. 30 (64 Pac. 855, 65 Pac. 1068, 54 L. R. A. 630, 87 Am. St. Rep. 634, 53 Cent. Law Jour. 128), Mr. Chief Justice BEAN, after reviewing numerous decisions involving the right of a riparian proprietor to use the water flowing through his land for irrigation, deduces the following conclusion as applicable to the arid region of the United States: "It is accordingly now quite generally held in this country and in England that, after the natural wants of all the riparian proprietors have been supplied, each proprietor is
