A resolution expressing support for the designation of the week of September 20 through September 27, 2025, as "National Estuaries Week".

S.Res. 418 is a non-binding resolution that would designate the week of September 20 through September 27, 2025, as National Estuaries Week. This resolution expresses support for highlighting the importance of estuaries, which are areas where rivers meet the ocean and serve as critical ecosystems for wildlife, fish, and plant life.

Estuaries are vital natural areas that provide numerous benefits to communities and the environment. They serve as nurseries for fish and shellfish, filter water, protect coastlines from storms, and support diverse habitats for birds and other wildlife. By designating a national week, the resolution would encourage public awareness and appreciation for these important ecosystems and the need to protect them.

The resolution passed the Senate on September 29, 2025, and now requires approval from the House of Representatives. If enacted, National Estuaries Week would serve as an annual observance to educate citizens about the ecological and economic value of estuaries and promote conservation efforts. This type of commemorative designation does not create new laws or regulations but rather focuses public attention on environmental protection and stewardship of these coastal ecosystems.
