Where accessible boat ramp access is actually published

Fewer than one public ramp in five has anything published about accessibility. Where the field exists, 15% of records affirm it. Everything else is silence, and silence is not a claim in either direction.

What the field means, and what it does not

Agencies use one checkbox for several different things: an accessible parking space, a firm route from that space to the water, a transfer platform on a boarding dock, or an accessible restroom nearby. The federal guidance behind them (linked below) sets requirements for gangway slope, handrails, and transfer systems on boarding facilities — but a single "accessible: yes" in a GIS layer does not tell you which of those is present.

• A boarding dock with a transfer platform is the feature most often meant, and the one least often stated.
• Gravel or grass parking defeats an otherwise compliant route; check the parking surface field on the ramp page.
• Where accessibility matters to your trip, call the managing agency. Every ramp page lists the operator, and a phone number where the agency published one.
