Agreement between the Government of the Czechoslovak Republic and the Government of the Polish People's Republic concerning the use of water resources in frontier waters.

The agreement between Czechoslovakia and Poland governs various aspects of water resource management in shared border areas, including technical and economic measures affecting water regimes, flood control, pollution abatement, and conservation. It stipulates that neither party may undertake works in frontier waters without the other's consent if it affects their water economy. The parties agree to cooperate on joint water resource development plans and to coordinate on river training works, water-use structures, and their maintenance. The agreement also covers timber floating, extraction of materials from watercourses, and information exchange on hydrological data and legal provisions. The document includes provisions for cross-border movement of workers engaged in water-related activities, customs exemptions for necessary materials and tools, and guidelines for tourist transport on specific frontier rivers. The agreement was set for an initial five-year term, automatically renewable unless denounced. An annex to the agreement details the procedures for issuing passes to workers crossing the border for water-related work and outlines the conditions for tourist transport on the Dunajec and Poprad rivers.
