Eddy does two different things with water, and it matters which one you are looking at.
24
Rivers Eddy has researched in Arkansas and Missouri. Each one has float thresholds calibrated against outfitter and agency guidance, access points verified against official sources, mapped hazards, float-time estimates by vessel, and shuttle logistics.
Eddy makes recommendations here.
14,216
Live USGS stream gauges across the United States. Eddy shows the reading, how it is trending, where it sits against its own history, and the National Weather Service forecast where one is published.
Eddy reports the measurement and recommends nothing.
Why the line is drawn there. A float verdict is not a reading — it is a reading compared against a level someone researched for that specific stretch of that specific river. Eddy will not attach a verdict to a gauge nobody has done that work for, because a guess and a researched call would then look identical on the same badge, and the badge is what people launch on.
Everything Eddy shows is one of two things, and they age very differently.
Gauge height and discharge from the USGS Water Services API, forecasts from the National Weather Service, reservoir levels and generation schedules from the US Army Corps of Engineers and Southwestern Power Administration, and weather. Eddy pulls these on a schedule and does not edit them. When a reading is older than expected, the reading is labelled stale rather than quietly shown as current.
Float thresholds, access-point coordinates and directions, hazards, float-time models, and outfitter and campground listings. These come from agency sources (NPS, Missouri Department of Conservation, US Forest Service, state parks, Recreation.gov), from outfitter guidance, and from Eddy's own review. They are correct as of when they were checked, not as of right now — a river can change with one flood, and a business can close between seasons.
Eddy's written daily read combines the two: it is generated from live readings and the researched thresholds for that river. It is a summary of data, not a substitute for judgement, and it never turns an unrated gauge into a rated one.

Rated gauges
Carry a floatability ladder, so they produce a verdict and not just a number. A river may have several — one per reach.
312
Access points
Put-ins and take-outs verified against an official source and approved for display. Pending pins are not counted.
22
Mapped hazards
Recorded hazards on curated rivers. Absence of a hazard here is not evidence that a stretch is clear.
87
Campgrounds
National Park Service campgrounds synced from the NPS API, plus private campgrounds researched by Eddy.
Curating a river means researching its thresholds, placing and verifying its access points, and mapping its hazards — so it happens river by river rather than by importing a list. If a river matters to you, tell us. Outfitters and campgrounds who want live conditions on their own site can use the free widgets, and developers can read these same figures from /api/coverage.
Every number on this page is read from Eddy's database when the page loads, not written into the page. Eddy is a planning tool: conditions change faster than any website, and you are responsible for your own safety on the river.
194
Outfitters & lodging
Outfitters, campgrounds, cabins and lodges. Businesses known to have closed permanently are excluded.
