The contract for the sale of the timber under which defendants are operating does not specify the manner of moving the logs from the premises. Any reasonable or workmanlike method which does no unnecessary injury to the land or damage to plaintiffs may be used by defendants.

Both plaintiffs and defendants rely upon the rules announced, in Kamm v. Normand, 50 Or. 9 (91 Pac. 448, 126 Am. St. Rep. 698, 11 L. R. A. (N. S.) 290). Plaintiffs claim the benefit of this language on page 14 of the official report:

“But a stream which is not such a highway cannot be made one by the use of dams or other artificial means, without first acquiring the rights of riparian proprietors: 1 Farnham, Waters, §139. Nor can a stream, navigable in its natural condition at certain stages of the water, be made so at other times by artificial means, such as flooding and the like. No one has a right to store water, and then suddenly release the accumulation, and thus increase the natural volume of the stream, and overflow, injure or wash the adjoining banks, or otherwise interfere with the rights of riparian owners. The riparian proprietor is entitled to the enjoyment of the natural flow of the stream with no burden or hindrance imposed by artificial means.” (Long list of authorities cited.)

Other authorities cited by plaintiffs include: Stephens v. City of Eugene, 90 Or. 167 (175 Pac. 855); Hansen v. Crouch, 98 Or. 141 (193 Pac. 454); Logan v. Spaulding Logging Co., 100 Or. 731, 736 (190 Pac. 349); Mendenhall v. Harrisburg Water Co., 27 Or. 38, 44 (39 Pac. 399); Hallock v. Suitor, 37 Or. 9, 12 (60 Pac. 384); Flinn v. Vaughn, 55 Or. 372 (106 Pac. 642).

*31 These authorities support the contention of plaintiffs, hut they are not applicable to the instant case. In all those cases the persons seeking injunctive relief sustained no contractual relations with the parties using the stream. Plaintiffs are bound by the contract to permit defendants to remove the timber from plaintiffs ’ premises. Defendants have an easement or license to enter upon plaintiffs’ land and to cut and remove the timber. Unless the manner in which defendants are operating is doing plaintiffs unnecessary injury, defendants are not trespassing.

Defendants rely upon this rule announced in Kamm v. Normand, above:

“Dams, dikes, embankments and the like may be constructed in or along floatable streams to facilitate their use (Union Power Co. v. Lichty, 42 Or. 563, 71 Pac. 1044), but not to the extent of injuring the riparian proprietors by retarding the flow of the water or sending it down in increased volumes to his injury or at times when the stream would not otherwise be navigable.” Page 15 in official report.

The stream involved is the North Pork of the Coquille River. It is stipulated that it is navigable for logging purposes during ordinary high water.

Defendants are not storing the water for the purpose of sending it on down the stream in increased volume. Plaintiffs are not lower riparian owners. Defendants are using deadheads for the purpose of storing enough water in the stream on plaintiffs’ premises to facilitate floating the logs in order to place them in the stream so that the logs will go out with the first freshet. Defendants are not using deadheads for the purpose of floating the logs down stream. They are not using deadheads to make the stream navigable for logs at a stage of water natu *32 rally unnavigable. Defendants have a right to utilize such means to facilitate the transportation of their logs by water to market: Kamm v. Normand, above.

Plaintiffs could with as much reason complain because defendants were cutting up their premises in transporting the logs to the river or other highway. But for the contract allowing defendants to enter upon said premises to cut and remove the timber, defendants would not be allowed to haul logs across plaintiffs’ land to the river. But for that same contract defendants would not be permitted to construct a temporary dam in the river on plaintiffs’ premises to facilitate the transportation of the logs from those premises.

Injunction is an extraordinary remedy. It will never be granted, except upon clear and convincing proof. Plaintiffs have not adduced such a preponderance of the evidence as to justify this court in enjoining the defendants from using the temporary dam or from placing other dams in a similar manner for the purpose of removing the logs from plaintiffs’ premises. The evidence convinces us that the use of a deadhead, as defendants are using it, is common in that section of the state. The evidence as to damage is speculative, uncertain and unsatisfactory. Defendants cannot cut and remove the timber from plaintiffs’ premises without doing more or less damage thereto. It is presumed that such damages were contemplated in fixing the price for the sale of the timber. We are convinced that defendants are removing the logs in a reasonable manner without unnecessary damage to plaintiffs.

It is immaterial to plaintiffs whether or not defendants have adopted the most reasonable way to remove the logs: Or. L., § 799, subd. 4. The logs *33 must be removed entirely at the expense of defendants. Plaintiffs are not injured if defendants have adopted a more expensive method for removing the logs than some other way might have been. Plaintiffs can complain only if the method employed by defendants was causing plaintiffs more damage than some other method would have caused them. Plaintiffs have failed to prove that to our satisfaction.

For these reasons the decree is affirmed.

Affirmed.
