Plain-English summary
Confidence: high · Complexity: moderate · Model: grok-4.5
This one already became law—the MAPWaters Act. In plain English, it tells federal land and water agencies to clean up and share the maps and rules for using public waterways for outdoor fun.
Agencies like the Forest Service, Park Service, BLM, Fish and Wildlife Service, and Bureau of Reclamation have to agree on shared data standards (within about 30 months) so their systems can talk to each other. Within five years, they must digitize and post online, as much as they can, GIS maps covering things like: which federal waters are open or closed to boats; seasonal shutoffs; motor, horsepower, fuel, speed, wake, and anchoring limits; which craft are allowed (canoes, motorboats, personal watercraft, and more); boat ramps, portages, and fishing access sites; and federal fishing closures, gear limits, and catch-and-release rules. Fishing-restriction data should update in real time when rules change; other access data at least twice a year. The public gets a way to send questions or comments.
If you boat, fish, paddle, or swim on federal waters, this is meant to make it easier to see what’s allowed and where to launch—without digging through a dozen agency sites. It does not rewrite fishing laws, change who controls the water, redefine “navigable waters,” or open or close waters. Irrigation canals are left out, and sensitive historic or archaeological details stay off the public maps. Agencies may partner with states, tribes, tech outfits, and the USGS, and they must report progress to Congress each year through 2034.

How a vote maps to positions
Impartial mapping: which issue position a Yea vs Nay advances. When a bill has multiple floor votes, each roll can have its own mapping. Bill-level entries (no roll listed) apply as a default when a roll has no specific map. Used for legislator alignment.
All rolls (bill default)
| Issue | Yea advances | Nay advances | Note |
|---|---|---|---|
| Public Lands & Wildlife | Access and multiple-use public lands | Status quo / reject this change | Yea backs standardizing and publishing recreation, access, and fishing-restriction maps for federal waterways; Nay prefers not adding these multi-agency data duties. |
| Regulation & Agency Oversight | Process, transparency, and reporting | Limit new reporting and disclosure mandates | Yea supports new interagency geospatial standards, public GIS posting, and annual progress reports; Nay treats those as extra agency mandates to avoid. |
