— This is an action to enjoin the defendant from removing earth from the channel of Mormon slough, a natural watercourse within the corporate limits of the city of Stockton. The earth referred to is sedimentary deposits brought down by the waters of the channel. The facts agreed upon show that “ for the protection from overflow and destruction of the property of and in said city, and the public streets and bridges and navigable waters of said Mormon channel, it was at all times *463mentioned in the complaint, and now is necessary to remove, or cause to be removed, said sedimentary deposits aforesaid in said Mormon channel.” The quantity of earth deposited has been increased by the construction under the direction of the United Sl.ates government, for the purpose of protecting the navigable "waters of the San Joaquin River, Stockton channel, and that porti on of Mormon channel lying west of Center Street, of restrai ning dams across Mormon channel below the point where defendant has been excavating and east of Center Street. The effect of these dams has been to make a restraining basin of Mormon slough above the points where they were erected. The street from which the earth was removed crosses the slough, but has not been used as a highway for the reason that it has never been bridged. The blocks of land described in the complaint, in front of which the digging was.done, are owned by the plaintiffs. The defendant claims the right to remove the earth under a resolution of the city council and a permit from the board of public works.

It is claimed by the appellants that the resolution of the city council and the permit given by the board of public works are void; that the work should have been done in accordance with the act of March 23, 1872 (Stats. 1871—72, p. 540); but that if the council or board of public works is clothed with the right to authorize the removal of earth from the streets, such authority can be granted only by ordinance.

We do not think the contentions of the appellants are sound. The charter of the city of Stockton, a ¡¡proved by the legislature March 2, 1389 (Stats. 1889, p. 577), provides: —

“Sec. 30. The council shall have power to ' pass ordinances. . . .

“9. To regulate, under the superintendence of a board of public works, the moving and anchoring of vessels within the waters of the city, and to prevent obstruction to the free navigation of the same.”

Section 147 provides that “the department of stree's and wharves shall embrace the control of the water front and wharves; of the streets, sidewalks, bridges and public thoroughfares .... of the watercourses and channels within the city,

. . . . and of everything of a public nature pertaining to said subjects.”

*464The mayor, the city surveyor, and the superintendent of streets constitute the board of public works, and are designated as the “ department of streets and wharves,” and it is their duty to see that the watercourses and channels are not obstructed by anything which will cause the waters thereof to overflow and injure or destroy the public streets or property of the city. The fact that the filling of the streets in front of plaintiffs’ land is a benefit to the land is immaterial. The city has the right to have the waters flow through the channel without interruption or obstruction, and to as full an extent as when Captain Weber, who owned the entire site of the city by grant from the Mexican government, transferred the streets and squares to the city (in 1851). The streets were conveyed by him to.the city authorities without any reservation, and with reference to a map made by him in 1850, in which Mormon channel Avas delineated from the Avestern to the eastern limits of the city.

Those who framed the charter doubtless saw that if the board of public Avorks were required in the exercise of their authority to proceed under an ordinance of the city council, great damage to the property of the city and its residents might be caused by obstructions in the watercourses Avithin the city. Authority Avas expressly conferred upon the board, therefore, to act in 1 respect to the control and protection of watercourses and channels directly, and no ordinance Avas necessary in the case at bar.

The act of March 23, 1872, was intended to provide against overfloAV, by authorizing the city authorities to Aviden and deepen the channel of Mormon slough from Hunter Street, a distance of five miles easterly. The act provides for condemnation proceedings, but it is not contended in this case that the respondent has removed, or attempted to- remove, any portion of the land belonging to plaintiffs, or has attempted to Aviden or deepen the channel. All defendant proposes to do is to remove a deposit of earth which has partially filled up the channel, and Avhich, if alloAved to remain, will tend to cause an overflow of the waters, and an injury to property of the city. The fact that the deposit is due in Avhole or in part to the acts of the United States government in improving the navigable portion *465of the stream below is immaterial. The city has the right to remove obstructions from a natural watercourse, so as to preserve it in its natural form, without regard to the cause of such obstruction.

The judgment is affirmed.
