What does this do?
HR 187 requires the National Park Service, Forest Service, Bureau of Land Management, Bureau of Reclamation, and U.S. Fish and Wildlife Service to collect, standardize, and publish waterway data in a single online location. Within five years, agencies must post maps covering boat ramp availability, motorized boat zones, speed restrictions, no-wake areas, seasonal closures, and fishing rules. Fishing restriction data must update in real time as changes occur, and agencies must provide a public feedback mechanism.
Who does it affect?
The law affects anyone who recreates on federally managed waters, including anglers, boaters, paddlers, and swimmers nationwide. The five named federal agencies are responsible for implementation and must report progress to Congress annually through 2034.
Why does it matter?
Waterway rules and access information are currently scattered across multiple agency websites and are not consistently current or easy to find. Consolidating that data into one standardized platform means users can look up current rules and access points before visiting a federal waterway.
