Fishing spots: where the public launches actually are

A fishing spot on this site is a place you can reach the water: a boat ramp, a hand-carry launch, a fishing pier or a bank access point. Almost all of them come from a registry a public agency publishes itself; the rest come from OpenStreetMap, which is the only source that covers ground no agency registry reaches. The map below plots all of them at once — zoom in to split a cluster, click a dot for what its source says.

12764 access points from 17 agency registries and OpenStreetMap, in 32 of the published cities. Each dot is a record its source publishes, not a place we have visited — click one for what that source says. Zoom in to split a cluster; the number on a cluster is how many points it holds.

What a dot is, and what it is not

Each dot is one record in a public list, almost always a government one. It carries the name that source uses, the water it names, and whatever it states about getting in: whether there is a trailer ramp or only a hand-carry slope, how many lanes, whether a fee applies, whether the site is accessible, and who operates it.

It is not a recommendation, and it is not a report from the water. Nobody on this project has stood on most of these ramps. The value of the record is that it is checkable: every one of them names the agency it came from and the date we read it, so a wrong line can be traced to its source rather than to us.

Some details are left out on purpose. Opening hours, the condition of the surface, whether the parking lot is paved, which pier has a roof — agencies publish all of it, and none of it survives a year without checking. A link to the agency’s own page covers those; a stale copy on our side would not.

Where the coverage is thin, and why

Sixteen states publish a launch registry we can read, name by name, with terms of use stated somewhere a person can find them. That is the whole reason the map looks uneven.

Wisconsin contributes 3,107 launches and Florida 2,624, because both states keep one statewide inventory and publish it whole. Virginia contributes two, because its server was unreachable the day we harvested. Louisiana, Minnesota, North Carolina and New York City all keep good registries that we cannot use yet: none of them states terms of use anywhere we could read, and data without stated terms does not go into a published product.

Texas is a different kind of gap. The state’s ramp registry has no name field at all — a launch is identified by the water it sits on and an internal code — so the map carries the state’s named paddling-trail access points instead, which is why Dallas and Houston show hand-carry launches rather than trailer ramps.

Using the map with the bite windows

The map answers where; the fishing forecast answers when. A launch that is twenty minutes away matters more on a morning when the major period opens at first light than on one when it falls at noon, and the city pages carry both the windows and the launches within twenty-five kilometres of town.

Florida is the one state deep enough in the data to deserve its own page: the Florida fishing spots guide sorts the state into five fisheries rather than a ranked list, because a Panhandle river and a Keys flat have nothing in common except the word spot.

When this map is the wrong tool

The map is the wrong tool for three trips. It will not help you fish from shore in a city with no registry, because bank access is exactly what most agencies do not list. It will not tell you which ramp is busy on a Saturday, because no registry publishes traffic. And it says nothing about whether the fish are there — that is the water temperature table and the species list on each city page, not a dot on a map. A phone in the boat covers the parts a static map cannot; the fishing app comparison walks through what those apps actually do with this kind of data.

How to read a record before you drive

Three fields decide most trips. Status tells you whether the agency has closed the site, and where it says unknown, it means the registry never carried a status field — not that the ramp is fine. Fee tells you whether launching costs money where the agency publishes that; a blank means no answer was given. Lanes tells you what the ramp can take: a single lane on a summer Saturday is a queue, and a hand-carry launch will not take a trailer at all.

After that, open the source’s own record. It is the only copy that updates when a ramp closes for repair, and every registry on this map is named, dated and linked in the data behind it. Those attributions travel with the files, and the terms of use set out what re-using them requires.
