People could find federal waterway rules in clearer online maps. The bill tells agencies to post data on access, closures, boating rules, and fishing limits. It does not change who controls the waters or what access exists now.
Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.
MAPWaters Act of 2025 is a Senate bill signed into law. The latest recorded action: Became Public Law No: 119-62.
Latest action on H.R. 187: Became Public Law No: 119-62.
Who this affects: This bill mainly affects people who boat, fish, swim, paddle, or use federal waters for recreation. It also affects federal agencies that manage the data, plus state and Tribal agencies that may help share it. Mapping and navigation companies could use the official data in apps and online maps.
Why this matters: Today, waterway recreation rules can be hard to find because they may sit in different agency systems and formats. This bill would push agencies to make those rules easier to find in online maps. That could help people follow the law, plan trips, and avoid unsafe or closed areas. Its main effect is better public information, not new access or new waterway rules.
You do not have to start with a blank letter. Modern Action turns the bill, your position, and the relevant congressional context into a message you can edit and send. The goal is to make contacting Congress clear, specific, and useful without forcing you to parse bill text or figure out the right office on your own.
