MAPWaters Act of 2025

This bill, the Modernizing Access to our Public Waters (MAPWaters) Act of 2025, would make it easier to find clear, up‑to‑date information about where people can boat and fish on federal waters. Two federal agencies must agree on common standards for collecting and sharing this information within 30 months, so data works the same across maps and websites.

Within five years, they must post online maps with details like when waterways are open or closed, no‑wake or speed zones, motor limits, direction‑of‑travel rules, and which types of boats or activities are allowed. They must also map boat ramps, portages, and fishing access sites (with open/closed dates), and share depth charts when possible. Fishing rules—such as closures, no‑take zones, gear or bait limits, and catch‑and‑release—must be included too. Waterway and access data must be updated at least twice a year, while fishing restrictions must be updated in real time. The public will have a way to ask questions or comment on the data. Sensitive historic or archaeological site information will not be disclosed.

The bill lets agencies work with states, Tribes, tech and mapping companies, and the U.S. Geological Survey, and use existing maps to avoid duplication. It also requires yearly progress reports through March 30, 2034. It does not change who controls navigable waters, fishing authority, or what waters are open to recreation today.

• Who is affected: Boaters, anglers, paddlers, and communities near federal waterways.
• What changes: Standard, easy‑to‑find online maps and rules for access, navigation, and fishing; regular updates; public feedback option.
• When: Standards set within 30 months; maps online within five years; updates ongoing; yearly progress reports through 2034 .
