3Interagency data standardization

This section would require the Secretaries, within 30 months after the Act becomes law, to work with the Federal Geographic Data Committee (the committee established under section 753(a) of the FAA Reauthorization Act of 2018, 43 U.S.C. 2802(a)) to jointly develop and adopt shared standards. These standards would make Federal databases compatible and interoperable with each other for collecting and sharing geospatial data about public outdoor recreational access to Federal waterways and about Federal fishing restrictions.

3. Interagency data standardization Not later than 30 months after the date of enactment of this Act, the Secretaries, in coordination with the Federal Geographic Data Committee established by section 753(a) of the FAA Reauthorization Act of 2018 ( 43 U.S.C. 2802(a) ), shall jointly develop and adopt interagency standards to ensure compatibility and interoperability among applicable Federal databases with respect to the collection and dissemination of geospatial data relating to public outdoor recreational access of Federal waterways and Federal fishing restrictions.

4Data consolidation and publication

This section would require each Secretary, within 5 years after the Act becomes law and to the maximum extent practicable, to digitize and publish online geographic information system (GIS) data covering three subject areas. For Federal waterway restrictions, the published data would have to include: whether a waterway is open or closed to entry or watercraft and under what conditions, including watercraft inspection, decontamination requirements, low-elevation aircraft rules, or diving rules; the dates a waterway is seasonally closed to entry or watercraft; the areas with restrictions on motorized propulsion, horsepower, or fuel type; the areas with anchoring restrictions, no-wake zones, exclusion zones, danger areas, or vessel speed restrictions; restrictions on direction of travel, including upstream or downstream travel; and which uses are restricted in each area, including whether canoes and other paddlecraft, rafts and driftboats, motorboats, personal watercraft, airboats, amphibious aircraft, hovercraft, oversnow vehicles and other motorized vehicles on frozen bodies of water, oceangoing ships, swimming, and other recreational activities the Secretaries decide are appropriate are allowed. For Federal waterway access and navigation information, the published data would have to include the location of boat ramps, portages, and fishing access sites under the agency's authority, the dates those facilities and sites are open or closed, and bathymetric information and depth charts where feasible. For Federal fishing restrictions, the published data would have to describe the location and geographic boundaries of restrictions on recreational and commercial fishing, including full or partial closures, no-take zones, and restrictions in or around marine protected areas; restrictions on the use of specific equipment or bait; and requirements for catch and release. The Secretaries would have to develop a process letting members of the public submit questions or comments about the waterway-restriction data and the access-and-navigation data described above; the section does not require this comment process for the fishing-restriction data. To the maximum extent practicable, the Secretaries would have to update the waterway-restriction data and the access-and-navigation data at least twice a year, and update the fishing-restriction data in real time as changes take effect. This section would not apply to irrigation canals and flowage easements. Any GIS data made publicly available under this section could not disclose information about the nature, location, character, or ownership of historic, paleontological, or archaeological resources, consistent with applicable law.

5Cooperation and coordination

This section would let the Secretaries coordinate and partner with non-Federal agencies and private-sector and nonprofit partners to carry out the Act, including State natural resource agencies, Tribal natural resource agencies, technology companies, geospatial data companies, and experts in data science, analytics, and operations research. The Secretaries could also enter into an agreement with a third party to carry out any provision of the Act. The Secretaries could work with the Director of the United States Geological Survey to collect, aggregate, digitize, standardize, and publish data on the Secretaries' behalf to meet the Act's requirements. For any data developed and distributed under the Act, the Secretaries would have to develop the data in accordance with applicable Federal, State, and Tribal law (including regulations), and include a notice that the geospatial data are subject to applicable Federal, State, and Tribal law (including regulations). To the extent practicable, the Secretary in charge of a given area would have to use or incorporate existing applicable data, maps, and resources when carrying out the Act, including data, maps, and resources developed and published under the Modernizing Access to Our Public Land Act (16 U.S.C. 6851 et seq.), under section 103 of division DD of the Consolidated Appropriations Act, 2023 (43 U.S.C. 776), or under other applicable law.
