Haikey Creek and Adams Creek Flooding in Broken Arrow

Which creeks flood in Broken Arrow, and where?

Haikey Creek, including its East and Middle Branches, and Adams Creek on the east side are the two named in local flood reporting. Elm Creek has also drawn warnings. South 273rd East Avenue has closed where it crosses Adams Creek, and roads around Haikey Creek closed in September 2018 heavy rain.

These are small watersheds, which is exactly why they matter. A creek with a short, built-up catchment responds to rain in hours, not days, so the hazard is flash flooding rather than a slow rise anybody can plan around. Roads go under first because a low crossing is the lowest point for some distance, and that is usually the first thing residents notice.

During the November 2024 storms, a local television news report described police watching the Haikey Creek and Adams Creek watersheds. In September 2018, heavy rain closed roads around Haikey Creek. Those two events, a few years apart, are the pattern: hard rain over a short period, water in the creek, crossings closed, and then water where there are buildings close to the channel.

How much rain does it take?

Less than the records suggest, because a small creek reacts to intensity rather than totals. The area's 24-hour record is 9.27 inches from May 26-27, 1984, and the wettest month on record is 18.18 inches in September 1971, but a few inches in an hour over a built catchment is enough to close a crossing.

Annual precipitation here is about 41 inches by NWS Tulsa's 1991-2020 normals, and it does not arrive evenly. The spring severe-weather season brings the storms that produce flash flooding alongside hail of an inch or more and tornadoes, and autumn fronts deliver heavy-rain events of their own: NWS Tulsa's October 2023 storm data describes 3 to 5 inches widely across the area with 6 to 8 inches locally.

For a homeowner the useful translation is this. Your exposure is not really the annual total; it is how fast your nearest channel fills and how much hard surface drains into it upstream. Two houses the same distance from a creek can behave completely differently depending on which side of a rise they sit on and where the storm drains discharge.

What did May 2019 teach Broken Arrow about the river?

That releases upstream decide the Arkansas River, and the warning time is short but real. Keystone Dam outflow climbed from 160,000 cubic feet per second on May 21 to 275,000 by May 27, and water took roughly 8 to 10 hours to reach south Tulsa and Bixby, giving downstream towns a usable but tight window.

Broken Arrow declared an emergency and urged voluntary evacuation in the mapped 100-year floodplain, mainly south of 131st Street, and warned specifically about Haikey and Elm Creek flooding. Downstream the river reached Bixby's high school and damaged several homes, Jenks Public Schools ended the year early, and a leaking levee near West 36th Street and South Elwood in Tulsa was rebuilt overnight. The total number of homes flooded was not something research established, so this page gives no figure.

Two lessons carried forward. First, river flooding here is announced in advance by release rates, so following those numbers during a wet spring is worth doing. Second, the creeks and the river interact: when the river is high, the creeks draining into it have less room to discharge. The May 2019 Arkansas River flood covers that event in full.

What do the FEMA maps actually show here?

FEMA's preliminary 2014 panels for Tulsa County label the East and Middle Branches of Haikey Creek and mark Zone AE along parts of Haikey Creek and the Arkansas River in south Broken Arrow. Those are preliminary drafts. The current effective maps are the ones that count, and they are published at FEMA's Map Service Center.

Zone AE means a mapped special flood hazard area with established base flood elevations, and it carries practical consequences for insurance and for building. But a preliminary panel is a proposal in a review process, not a determination, and panels get revised. Quoting a draft as though it were current is how a homeowner ends up badly informed about their own property.

So do the one thing that actually answers the question: look your address up on the effective map at FEMA's Map Service Center. This page will not state a zone for any address, any street or any subdivision, because the honest answer always depends on the current panel and on the elevation of the specific parcel. If a contractor or a seller tells you your zone, ask which panel and which date.

• Search your address on FEMA's Map Service Center and note the panel number and effective date.
• Treat anything labelled preliminary as a draft under review, not a determination.
• A mapped zone describes a parcel, not a neighbourhood, so a neighbour's status tells you little.
• Elevation relative to the channel matters more than distance from it.
• Flood cover is generally arranged separately from a standard homeowners policy.
• Keep a copy of whatever map panel you relied on, with its date.

What does creek flooding do inside a house?

It arrives dirty. Water that has run across ground, through storm drains and out of a creek carries silt, fuel residue and whatever the catchment holds, so porous materials are usually removed rather than dried, and the cleaning that follows is as much of the job as the water removal.

A supply-line failure puts clean water on a floor and much of the building can often be dried in place. Flood water is the opposite case: carpet and pad, insulation, chipboard and the lower portion of drywall generally come out, hard surfaces are cleaned, and the crew works to stop contamination travelling into dry rooms. Those are different line items, not larger ones.

Then the drying starts, and it is slower than people expect because wall cavities and floor assemblies hold water where air cannot reach it. Flood water damage restoration describes the sequence, and structural drying and dehumidification covers why the equipment stays in the room for days rather than hours.

What should you do when a crossing near you goes under?

Stay out of the water and off the road. Six inches of moving water can take you off your feet and a crossing can hide a scoured-out roadbed. Move vehicles and contents to higher ground while you still can, and photograph the property before water reaches it if there is time.

Closed crossings are closed for a reason, and the reason is often that nobody can see what is left of the road surface. Turning around costs minutes; the alternative is a vehicle in a creek. The same applies on foot, and it applies doubly to children, who misjudge moving water badly.

Inside the house, the useful work is vertical. Get electronics, documents, photographs and anything irreplaceable upstairs or up on blocks, move vehicles out of low parking, and if you have a sump or a floor drain, know whether it is working before you need it. The hour before water arrives is worth far more than the hour after.

Is a creek flood an insurance claim?

Flood water arriving over the ground is generally handled outside a standard homeowners policy and arranged separately, which is why mapped zones matter so much here. Your policy and your insurer decide your case. Document everything regardless, because documentation is useful under every policy and costs nothing.

The distinction insurers draw is about where the water came from rather than what it ruined. Water escaping from your own plumbing and water rising out of a creek are different perils even when they soak the same carpet, and sewer or drain backup during the same storm is a third category that is commonly an endorsement rather than default cover.

Photograph before you clean, keep receipts for emergency work, note times, and keep a log of calls. Water damage insurance claims in Oklahoma sets out the general pattern and names the Oklahoma Insurance Department as the complaint route. Nothing on this site predicts an insurer's decision.

What reduces the risk before the next storm?

Know your elevation relative to the nearest channel, keep gutters, downspouts and yard drains clear, direct discharge away from the foundation, and know the route out that does not cross a low creek bridge. Then look up the current effective FEMA panel for your address and keep a copy.

Most of what a homeowner can control is drainage close to the building: clear gutters, extensions carrying downspout water well clear, grade falling away from the walls, and yard drains that are not full of leaves in October. None of that stops a creek, but it decides how much of an ordinary heavy rain ends up against your foundation, which is the more common problem by far.

After that it is planning. Know which crossings near you close, keep an alternative route in mind, and have somewhere to put the car.
