Waterway regulation refers to the set of laws and guidelines that govern the use and management of rivers, lakes, and other bodies of water. These regulations aim to protect water quality, ensure safe navigation, and preserve aquatic ecosystems. Agencies like the Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers play key roles in enforcing these rules. Regulations may cover various activities, including fishing, boating, and pollution control. They often require permits for construction projects near waterways and set limits on harmful discharges. By managing these activities, waterway regulation helps maintain the health of aquatic environments and supports sustainable use of water resources.
