Arkansas River Levels
Arkansas watches genuinely big water, and big water gives notice: its crests form upstream days before they arrive. Here are 6 Arkansas gauges read live from USGS, each against the flood stage NWS has established for it, plus the live NWS alert feed and each gauge's record crest.
The biggest gauge on this page drains 160,000 square miles of river countryWhere Arkansas rivers stand against their flood stages
Each card below carries two numbers from two agencies: the stage USGS is reporting at the gauge right now, read live from waterservices.usgs.gov when this page loaded, and the flood stage NWS has established for that same gauge. The “above” or “below” line is the subtraction between them and nothing more. A gauge below its thresholds is exactly that, not a promise about the next storm.
Reading current stage from waterservices.usgs.gov.
Stages are the U.S. Geological Survey's own readings, fetched live in your browser and shown without adjustment; provisional data are marked and may be revised by USGS. The action, minor, moderate and major thresholds are established per gauge by the National Weather Service and were snapshotted from the National Water Prediction Service; “above” or “below flood stage” is arithmetic on those two agency numbers and nothing more. A reading describes the gauge's own reach, not any particular property near it. Sources: USGS and NWS NWPS
Find the gauges nearest you
Every reading on this page belongs to one gauge on one reach of river, and the gauge nearest you is the one describing your water. This tool ranks the Arkansas gauges on this page (and, where the state line is closer than the water, the rest of the site's registry) by distance from a ZIP code, with each gauge's live stage against its flood stage. The distance is printed on every row because a gauge 40 miles away describes that river, not your street.
Active NWS flood products for Arkansas
Gauges show water that has already arrived. Warnings arrive first, and they cover the thousands of Arkansas streams that have no gauge at all, which is where flash floods do their killing. This feed is read live from api.weather.gov and republished exactly as NWS issued it.
Reading active alerts from api.weather.gov.

The product names have precise meanings. A Flood Warning, in NWS's words, is “a release by the NWS to inform the public of flooding along larger streams in which there is a serious threat to life or property”. A Flash Flood Warning means flash flooding is in progress, imminent, or highly likely: act first, check the river later.
What flood stage means at each Arkansas gauge
Flood stage is not one number. NWS establishes a ladder of thresholds for each individual gauge, in feet of stage at that gauge, because the same depth of water means different things in different valleys. Here is Arkansas's committed ladder, then the agency's own definitions of each rung.
| Gauge | County | Action | Flood | Moderate | Major | Record crest |
|---|---|---|---|---|---|---|
| Arkansas River at Pendleton, AR | Desha | 30 ft | 31 ft | 32 ft | 33 ft | 37.6 ft (2019) |
| AR River at Van Buren, AR | Crawford | 22 ft | 22 ft | 26 ft | 31 ft | 40.8 ft (2019) |
| Red River at Spring Bank, AR | Miller | 33 ft | 37 ft | 39 ft | 41 ft | 44.2 ft (2015) |
| White River near Augusta, AR | Woodruff | 25.5 ft | 26 ft | 34 ft | 36 ft | 40.8 ft (1945) |
| Arkansas River at Pine Bluff, AR | Jefferson | 40 ft | 42 ft | 44 ft | 45 ft | 52.1 ft (1943) |
| Red River at Fulton, AR | Hempstead | 25 ft | 27 ft | 30 ft | 32.5 ft | 37.4 ft (1945) |
Thresholds are the National Weather Service's established gage heights for each point, snapshotted from the National Water Prediction Service on 2026-09-02; they change rarely. “None set” means NWS has not established that category for the gauge, which is common at remote points. Record crests are NWS's own historic crest listings.
National Weather Service Glossary, Action Stage“The stage which, when reached by a rising stream, represents the level where the NWS or a partner/user needs to take some type of mitigation action in preparation for possible significant hydrologic activity. The appropriate action is usually defined in a weather forecast office (WFO) hydrologic services manual.”
National Weather Service, High Water Level Terminology“Minor Flooding is defined to have minimal or no property damage, but possibly some public threat. A FLOOD ADVISORY product is issued to advise the public of flood events that are expected not to exceed the minor flood category.”
National Weather Service, High Water Level Terminology“Moderate Flooding is defined to have some inundation of structures and roads near the stream. Some evacuations of people and/or transfer of property to higher elevations may be necessary. A FLOOD WARNING should be issued if moderate flooding is expected during the event.”
National Weather Service, High Water Level Terminology“Major Flooding is defined to have extensive inundation of structures and roads. Significant evacuations of people and/or transfer of property to higher elevations are necessary. A FLOOD WARNING should be issued if major flooding is expected during the event.”
The threshold names and definitions are the National Weather Service's; the one line glosses above each quote are ours.
National Weather Service, High Water Level Terminology“Flood categories are terms defined for each gage location that describe or categorize the observed or expected severity of flood impacts in the corresponding stream segment or nearby stream. The severity of flooding at a given stage is not necessarily the same at all locations along a stream due to varying channel/bank characteristics on portions of the stream.”
What NWS says happens at these stages, in its own words
For 6 of these gauges, NWS publishes impact statements: sentences tied to specific stages, naming the roads and places that go under. They are the most local flood information that exists for these reaches, they are federal writing republished verbatim, and they are exactly what the thresholds above are made of.
Arkansas River at Pendleton, AR
NWS impact statement, National Water Prediction Service“Residences inside the levee just upstream of the Pendleton Bridge are affected.”
NWS impact statement, National Water Prediction Service“Estimated crest of June 1957 prior to establishment of a gage at the site.”
AR River at Van Buren, AR
NWS impact statement, National Water Prediction Service“minor lowland flooding occurs along the shoreline from the I-540 bridge east towards Lavaca.”
NWS impact statement, National Water Prediction Service“near catastrophic flooding occurs along the Arkansas River. Approaches to the Highway 71B Midland bridge and I-540 bridge may be covered by high water. The Highway 64 bridge approach in Oklahoma is flooded. The port of Fort Smith and nearby businesses are severely flooded.”
Red River at Spring Bank, AR
NWS impact statement, National Water Prediction Service“Expect flooding in between levees with backwater flooding affecting the lower Sulphur River.”
NWS impact statement, National Water Prediction Service“Expect major flooding between and near levees. The railroad bridge at Garland City, Arkansas must be closed and leveed over at this point. Expect major backwater flooding through the lower Sulphur River to approaching Lake Wright Patman.”
When the big rivers through Arkansas run high
Arkansas River at Pendleton, AR drains 160,000 square miles, which means its crests are built from weather that happened upstream, days earlier and often in other states. That is why NWS river forecast centers can publish stage forecasts for 6 of the gauges on this page, and why a Arkansas flood fight on the big water is a scheduled event in a way no flash flood ever is. The chart below shows the months the record says to watch.
The deepest water on this page's record: 40.8 feet at AR River at Van Buren, AR in 2019, which is 18.8 feet above that gauge's flood stage. NWS keeps the crest lists, and its definition is the useful one here:
National Weather Service, High Water Level Terminology“Record flooding is flooding that equals or exceeds the highest stage or discharge at a given site during the period of record keeping.”
The part no gauge can do
NWS flood safety, quoted verbatimMost Arkansas streams have no gauge, and flash floods happen on exactly that water. NWS says both halves of this plainly, and its words belong on this page more than any reading does.
First, who dies in floods, from the agency that counts:
National Weather Service, Turn Around Don't Drown“Each year, more deaths occur due to flooding than from any other thunderstorm related hazard. The Centers for Disease Control and Prevention report that over half of all flood-related drownings occur when a vehicle is driven into hazardous flood water. The next highest percentage of flood-related deaths is due to walking into or near flood waters.”
National Weather Service, Turn Around Don't Drown“A mere 6 inches of fast-moving flood water can knock over an adult. It takes just 12 inches of rushing water to carry away most cars and just 2 feet of rushing water can carry away SUVs and trucks. It is NEVER safe to drive or walk into flood waters.”
National Weather Service, Turn Around Don't Drown“Never drive around the barriers blocking a flooded road. The road may have collapsed under that water.”
Those three passages are the NWS Turn Around Don't Drown campaign in full working order, and they apply to every water crossing in Arkansas, gauged or not. Second, the limits of pages like this one. NWS, writing about the state with more rivers and fewer gauges than any other, is candid about the network:
National Weather Service, High Water Level Terminology“There are uncountable numbers of streams and lakes of various sizes in Alaska and only a very small fraction of these have gages that monitor the water levels.”
National Weather Service, High Water Level Terminology“People living or recreating near any stream or lake should identify the closest gage that can be used as an index for the expected water level changes at their location.”
That is the frame for everything above: a gauge is an index for its reach, the nearest one is worth knowing, and a Flash Flood Warning outranks any reading on this page. The NWS definition that makes the speed clear:
National Weather Service Glossary, Flash Flood“A rapid and extreme flow of high water into a normally dry area, or a rapid water level rise in a stream or creek above a predetermined flood level, beginning within six hours of the causative event (e.g., intense rainfall, dam failure, ice jam). However, the actual time threshold may vary in different parts of the country. Ongoing flooding can intensify to flash flooding in cases where intense rainfall results in a rapid surge of rising flood waters.”
Flood zones are FEMA's to determine. Whether a property sits in one is an official determination tied to flood insurance, and it is made on FEMA's own maps. In FEMA's own words:
FEMA Flood Map Service Center“The FEMA Flood Map Service Center (MSC) is the official public source for flood hazard information produced in support of the National Flood Insurance Program (NFIP). Use the MSC to find your official flood map, access a range of other flood hazard products, and take advantage of tools for better understanding flood risk.”

Where the Arkansas figures come from
Two agencies, kept apart. The readings are live from USGS: stage from the instantaneous values service, discharge and its percentile context from the same daily services the drought pages use. The thresholds, impact statements and crests are NWS's, snapshotted from the National Water Prediction Service on 2026-09-02; flood stages are established gage heights that change rarely, and the snapshot date is printed wherever they appear. The alerts are live from api.weather.gov.
Which gauges appear is our choice, made once and stated plainly: active USGS stage gauges that NWS resolves to a forecast point with a published flood stage, ranked by drainage area so the rivers people actually check come first, at most two per river, spread across the state, with canals and diversions excluded. Gauges below dams are kept on purpose: regulated or not, they are the gauges downstream towns watch. The thing that is missing on purpose: there is no flood score, index or rating of ours anywhere on this site, and no flood zone map either. NWS owns the thresholds, USGS owns the readings, FEMA owns the maps.

A note on what the National Water Prediction Service is, in our words. It is the NWS platform that carries every official river gauge page: observed stages, forecast crests where a river forecast center issues them, the flood stage ladder, impact statements and historic crests. When a reading on this page makes you want a second opinion, the NWPS gauge page linked on every card is the authoritative one.
