MAPWaters Act of 2025

This bill directs federal land and water agencies to standardize and publish digital data about public recreational use of federal waterways. The Secretaries of Agriculture and the Interior, working across the Bureau of Reclamation, National Park Service, Bureau of Land Management, Fish and Wildlife Service, and Forest Service, must adopt common interagency data standards within 30 months. Within five years they must put online geographic-information-system data covering three areas: waterway restrictions such as closures, no-wake zones, and limits on which craft may be used; access and navigation information such as boat ramps, portages, fishing access sites, and depth charts where feasible; and fishing restrictions such as closures, no-take zones, and gear or bait rules. The agencies must let the public submit questions and comments, update restriction data at least twice a year, and update fishing-restriction data in real time. The bill lets the agencies partner with states, tribes, private firms, and the U.S. Geological Survey, and it shields sensitive historic, paleontological, and archaeological site data from disclosure. It requires annual progress reports through March 30, 2034. The bill does not change the definition of navigable waters, agency jurisdiction over waters or fisheries, or existing public access to hunting, fishing, and recreation.

At least 5 organizations named this measure in a lobbying filing. A floor, not a total: they were counted by the client name on 20 quarterly reports filed by 5 organizations lobbying for themselves in 2025 Q1, 2025 Q2, 2025 Q3, 2025 Q4, 2026 Q1, 2026 Q2 and 2026 Q3. An organization that lobbied this measure without naming it is not counted here.

The filings record that lobbying was reported on the measure. The form has no per-bill dollar figure and no field for a position, so nothing here says how much was spent or which side an organization took.

The organizations named: Backcountry Hunters & Anglers; Theodore Roosevelt Conservation Partnership; The Marine Retailers Association of the Americas; American Sportfishing Association; Trout Unlimited. Listed as filed. They are every client name on the filings counted here.

From the LD-2 quarterly lobbying filings published at lda.gov by the Senate Office of Public Records. Read for 2025 Q1, 2025 Q2, 2025 Q3, 2025 Q4, 2026 Q1, 2026 Q2 and 2026 Q3. Our copy holds 24 fewer filings for 2025 Q1, 39 fewer filings for 2025 Q2, 42 fewer filings for 2025 Q3, 33 fewer filings for 2025 Q4, 28 fewer filings for 2026 Q1, 48 fewer filings for 2026 Q2 and 218 fewer filings for 2026 Q3 than the Senate's register counts, so those quarters are the filings we could read rather than every one filed. 2026 Q4 is still inside its filing window, so that quarter is only the filings posted so far.
