Reclamation op Swamp and Tide Land — Damming Tributary to Navigable Stream.—The owners of swamp-land, or of marsh and tide land, purchased from the state, have no rights in the reclamation of their lands, superior to the rights of the public to the use of navigable streams; and if a tributary to a navigable stream is necessary to its navigability, the owner of such land upon which the tributary is situated has no right to dam it in order to effect the reclamation of his land.

Id.—Public Nuisance — Action by State — Findings — Omission op Material Finding. —In an action by the state to abate as a public nuisance the damming of sloughs by the owner of marsh and tide lands, seeking to reclaim the same, where it appeared that the water in the sloughs came from the ocean, over Eel River Bar and through Salt River, a navigable stream, and rose and fell with the tide, and issues were joined both as to the navigability of the sloughs, and as to whether the dam substantially interfered with the navigability of Salt River and Eel River Bar, mere findings to the effect that the sloughs were not navigable cannot support a judgment for the defendant; and the omission expressly to find upon the material ■issue as to interference with the navigable streams to which the sloughs were tributary, is ground for reversal.

Id.—Dams upon Non-navigable Sloughs—Obstruction op Navigable Stream.—If the dams upon these sloughs, though the sloughs be not themselves navigable, result in the obstruction of Salt River as a navigable stream, they constitute a public nuisance.

Id. — Use op Property Creating Public Nuisance.—No man may use his own property so as to create a public nuisance; and the owner of tide-lands is forbidden by section 2 of article XV of the constitution of the state to obstruct the free navigation of any navigable water in the state.
