Missouri Sunshine Law, also known as "Chapter 610 of the Revised Statutes of Missouri", "...is the embodiment of Missouri's commitment to openness in government." This means that meetings, records, votes, deliberations, and actions of public governmental bodies are open to the public unless otherwise provided by law.

Most state and local entities ("public governmental bodies") must comply with the Sunshine Law. This includes water districts.

• "Any department or division of the state, of any political subdivision of the state, of any county or of any municipal government, school district or special purpose district including but not limited to sewer districts, water districts, and other subdistricts of any political subdivision;"
