MAPWaters Act of 2025

Dec 26, 2025
Dec 26, 2025

Summary

Requires federal agencies to create a single, online system with maps and rules for using public waterways for activities like boating and fishing.

What problem does this solve?

Information about using federal waterways is often scattered across different agencies and hard to understand. This law requires agencies to combine this data into a single, easy-to-use online source for the public.

Who does this affect?

  • Recreational boaters and anglers
  • Outdoor recreation businesses
  • Federal land management agencies

What does this law do?

Standardizes waterway data across agencies
Requires federal agencies to create a common format for all data about public access to federal waterways, making it easier to combine and share information.
Creates public online database of waterway information
Mandates that agencies digitize and publish maps and data online, showing waterway restrictions, access points like boat ramps, and fishing rules.
Requires frequent data updates
Ensures the online information stays current by requiring general data to be updated at least twice a year and fishing restriction data to be updated in real time.
Allows for public and private partnerships
Permits federal agencies to work with states, tribes, and private companies, including technology and data firms, to help collect and publish the required information.
Protects sensitive information
Prevents the public release of data that would show the location of historic, paleontological, or archaeological resources.

What is the real world impact?

Creates business opportunities for tech companies
Requires the government to digitize a large amount of data, which could lead to contracts for private technology and geospatial data companies to build and manage these new systems.
Makes it easier for people to enjoy public waters
Gathers scattered information from multiple federal agencies into one easy-to-access online source. This helps boaters, fishers, and others find rules and access points for recreational activities on federal waterways.

When does this start?

This law sets several deadlines for federal agencies to complete their work over the next few years.
Data standardization deadline
Within 30 months of the law's passage, agencies must develop and adopt common standards for their waterway data.
Data publication deadline
Within 5 years of the law's passage, agencies must digitize and make all waterway access and restriction data available to the public online.
Annual progress reports
Starting 1 year after the law is passed, agencies must submit annual reports to Congress on their progress until March 30, 2034.
