In the case of United States v. Alaska (1974), the U.S. Supreme Court was tasked with resolving a dispute over ownership of submerged lands and resources in three Alaskan rivers: The Copper, Susitna, and Yukon. The State of Alaska claimed that it had gained title to these lands upon its admission to the Union in 1959 under the Submerged Lands Act which granted coastal states rights to offshore resources up to three miles from their coastlines. However, the federal government argued that these rivers were navigable waters at high tide and therefore fell under federal jurisdiction as per common law principles established by previous court rulings on similar matters. The Supreme Court ruled unanimously in favor of Alaska, stating that even though parts of those rivers might be affected by tides, they did not constitute "seaward boundaries" as defined by Congress when it passed legislation granting coastal states control over submerged lands within their borders up to three nautical miles out into sea or ocean bodies adjacent them. This decision clarified how such disputes should be resolved going forward - namely through careful interpretation and application of relevant laws rather than relying solely on historical legal precedents related specifically to tidal influence on water bodies.

In the dissenting opinion for United States v. Alaska, 1974, Justice Douglas argued that the majority's decision to grant submerged lands and their resources to states was a departure from previous precedents which held these areas as public trust. He contended that this shift in policy could potentially lead to over-exploitation of natural resources by individual states at the expense of national interests. Furthermore, he expressed concern about potential conflicts between state and federal authorities regarding resource management and environmental protection policies on these lands. In his view, maintaining federal control over submerged lands would better serve long-term conservation efforts and ensure equitable access for all Americans rather than just residents of coastal states.
