Modernizing Access to Our Public Waters Act

S 3123 requires federal agencies like the National Park Service and Forest Service to digitize and publish online accessible maps of water access rules for public waterways. It mandates making clear data available about seasonal closures, boat ramp locations, motorized vehicle restrictions, fishing equipment rules, and no-take zones within 4 years of enactment. This directly affects recreational users (fishers, boaters) and commercial operators who need to navigate federal waterways. The bill does not create new restrictions but standardizes how existing rules are shared, with agencies updating the data twice yearly for access rules and in real-time for fishing restrictions. It explicitly excludes irrigation canals and archaeological sites from the data requirements.
