Article 335.
No dues of any kind other than those provided for in the present Part shall be levied along the course or at the mouth of these rivers.
This provision shall not prevent the fixing by the riparian States of customs, local octroi or consumption duties, or the creation of reasonable and uniform charges levied in the ports, in accordance with public tariffs, for the use of cranes, elevators, quays, warehouses, etc.
Article 336.
In default of any special organization for carrying out the works connected with the upkeep and improvement of the international portion of a navigable system, each riparian State shall be bound to take suitable measures to remove any obstacle or danger to navigation and to ensure the maintenance of good conditions of navigation.
If a State neglects to comply with this obligation any riparian State, or any State represented on the International Commission, if there is one, may appeal to the tribunal instituted for this purpose by the League of Nations.
Article 337.
The same procedure shall be followed in the case of a riparian State undertaking any works of a nature to impede navigation in the international section. The tribunal mentioned in the preceding Article shall be entitled to enforce the suspension or suppression of such works, making due allowance in its decisions for all rights in connection with irrigation, water-power, fisheries, and other national interests, which, with the consent of all the riparian States or of all the States represented on the International Commission, if there is one, shall be given priority over the requirements of navigation.
Appeal to the tribunal of the League of Nations does not require the suspension of the works.
Article 338.
The régime set out in Articles 332 to 337 above shall be superseded by one to be laid down in a General Convention drawn up by the Allied and Associated Powers, and approved by the League of Nations, relating to the waterways recognized in such Convention as having an international character. This Convention shall apply in particular to the whole or part of the above-mentioned river systems of the Elbe (Labe), the Oder (Odra), the Niemen (Russstrom-Memel-Niemen), and the Danube, and such other parts of these river systems as may be covered by a general definition.
Germany undertakes, in accordance with the provisions of Article 379, to adhere to the said General Convention as well as to all projects prepared in accordance with Article 343 below for the revision of existing international agreements and regulations.
Article 339.
Germany shall cede to the Allied and Associated Powers concerned, within a maximum period of three months from the date of which notification shall be given her, a proportion of the tugs and vessels remaining registered in the ports of the river systems referred to in Article 331 after the deduction of those surrendered by way of restitution or reparation. Germany shall in the same way cede material of all kinds necessary to the Allied and Associated Powers concerned for the utilization of those river systems.
The number of the tugs and boats, and the amount of the material so ceded, and their distribution, shall be determined by an arbitrator or arbitrators nominated by the United States of America, due regard being had to the legitimate needs of the parties concerned, and particularly to the shipping traffic during the fire years preceding the war.
