9 lakes, from data published on each lake's page. See all states.
These lakes have at least one public boat ramp or trailer launch listed on their LakeRipple page; ramps marked resident-only or needing a resident permit sticker are not counted. Ramp records come from state access-site lists (for example NH Fish and Game, Minnesota DNR and NYSDEC) and, where a state publishes no list, from boat ramps mapped on OpenStreetMap. Each lake page shows the ramp type, owner, parking and fees where the source gives them. Horsepower limits, no-wake rules, inspection stations and resident-only ramps are common, so read the lake page's boating rules and confirm with the site owner before you tow.
