1938- Congress passed HR 8982, an amendment to the Alien Fishing Act (50 Stat. 639). The amendment clarified the earlier laws on salmon fishing in Alaskan waters by limiting commercial salmon fishing in the vicinity of Bristol Bay, Alaska, to U.S. citizens only. The act was enforced by the Coast Guard.
1942- A Coast Guard aircraft directed a Royal Navy trawler to a life boat with 24 survivors off the coast of North Carolina
1952- The breakup of ice in the Missouri River
and its tributaries at Bismarck, North Dakota, and above, and on the Big Sioux, created the worst flood conditions in that area in thirty years. U.S. Coast Guard personnel rendered assistance in that major disaster, utilizing small boat equipment, mobile radio stations, automotive equipment, helicopters, and fixed wing aircraft. The Coast Guard evacuated stranded persons, transported critical relief supplies, evacuated livestock from low ground, transported personnel engaged in levee construction, and generally assisted the Red Cross, local, state, civil, and military authorities.
