Last Updated: April 2025 | Based on FEMA, NOAA, and USGS data
Iowa has had 18 federally declared disasters since 2016. That number matters if you live in Davenport, because it is not spread evenly, severe storms account for 8 of those declarations, floods account for 5, and three of them were biological events layered on top of an already stressed emergency infrastructure. In 2024 alone, Iowa saw three separate federal declarations between May and June, two of which explicitly listed tornadoes and flooding in the same event title. For a city sitting directly on the Mississippi River without a continuous flood wall, that pattern is not background noise. It is your planning calendar.

Key Takeaways
- Iowa’s dominant threat is the combination of severe storms and flooding, not flooding alone. Your prep has to cover both.
- Three of Iowa’s last eight severe storm declarations explicitly included tornadoes. Davenport is in that corridor.
- The August 2023 standalone flood declaration came mid-summer, outside the typical spring window, don’t assume flood season has an off switch.
- Flood insurance has a 30-day waiting period. The time to buy it is not during a watch.
- Scott County Emergency Management and the NWS Quad Cities office are your two most reliable local sources during an active event.
Severe Storms and Flooding Arrive Together in Iowa. Plan Accordingly
Look at the 2024 declaration titles: “Severe Storms, Flooding, Straight-Line Winds, and Tornadoes” on June 24, and “Severe Storms, Tornadoes, and Flooding” on May 24. These are not sequential events, they are compound events where wind damage, tornado touchdowns, and floodwater arrived in the same operational window. For Davenport residents, that means your emergency response cannot be siloed. A plan that only addresses river cresting will fail you when a straight-line wind event knocks out power and drops six inches of rain in three hours at the same time.
Practically, this means your home checklist needs to cover two simultaneous threats: structural integrity against wind and water intrusion from below and above. Check basement window wells for drainage capacity. Confirm your sump pump has a battery backup, not just a plug-in backup, but one tested under load. Trim large limbs within striking distance of your roof before storm season. And know which room in your house sits highest and farthest from windows, because you may need to shelter in place for a tornado warning while the basement is already taking on water.
The Mississippi River Is Not Your Only Flood Source
Davenport’s flood conversation tends to center on the Mississippi River crest, and that attention is warranted, the river’s flood stage at the Davenport gauge is 22 feet, and major flood stage begins at 25 feet. Monitor the real-time gauge at water.weather.gov and check the NWS Quad Cities forecast discussion at weather.gov/dvn during any significant rainfall event upstream.
But the August 2023 federal flood declaration, issued in late summer, not spring, is a reminder that urban drainage flooding and creek overflow can trigger federal disaster thresholds independently of the Mississippi. Duck Creek and its tributaries run through residential Davenport neighborhoods. Heavy convective rainfall in July or August can overwhelm those systems within an hour. If your home sits in a low point relative to any creek or drainage channel, your flood risk is year-round, not seasonal. Use the FEMA Flood Map Service Center to confirm your property’s Special Flood Hazard Area status, and don’t assume that being outside the 100-year floodplain means you’re clear of the 2023 scenario.
Insurance: The 30-Day Gap That Catches Davenport Residents Off Guard
Standard homeowners policies do not cover flood damage. The National Flood Insurance Program (NFIP) fills that gap, but it comes with a 30-day waiting period before coverage activates. With three federal disaster declarations hitting Iowa inside a 13-month window in 2023–2024, the window between “this season looks bad” and “the river is cresting” is not 30 days. Contact your insurance agent now, before the NWS Quad Cities issues the first significant watch of the season.
When you call, ask specifically about contents coverage. NFIP building coverage protects the structure, but your furniture, appliances, and stored items in a basement require a separate contents policy. Document your belongings now: walk every room with your phone camera, open closets, capture serial numbers on appliances. Store that video in a cloud account you can access from a shelter or a relative’s home, not just on a local hard drive that might be underwater.
Tornado Overlap: What Three Declarations in One Year Means for Davenport
Iowa’s single tornado declaration in the dataset (May 2024) sits alongside two severe storm declarations that same month, one explicitly naming tornadoes. Scott County falls within the Quad Cities tornado corridor, and the NWS Storm Prediction Center routinely includes the area in enhanced or moderate risk outlooks during spring and early summer. That is not a reason to panic, but it is a reason to have a shelter plan that does not require going to the basement if the basement is at flood risk.
Identify your interior shelter option on an upper floor: a bathroom, a closet, or a hallway away from exterior walls. If your home has no above-grade interior room, know the nearest community shelter in advance, not during a warning. Davenport’s city emergency management page and Scott County Emergency Management publish shelter locations ahead of storm season.
Your 72-Hour Kit, Calibrated for Iowa’s Compound Threats
A generic kit list works for a generic disaster. Iowa’s record argues for a few specific additions:
- One gallon of water per person per day for at least three days (more if you have pets)
- Three-day supply of non-perishable food, stored above floor level in case of basement flooding
- Battery-powered or hand-crank NOAA weather radio (power outages from straight-line winds can last days)
- Flashlight and spare batteries
- First aid kit with a two-week supply of any prescription medications
- Waterproof bag with insurance cards, passports, birth certificates, and medical records
- Wrench or pliers to shut off gas and water mains
- N95 respirators, relevant for post-flood mold remediation and any biological event overlap
- Cell phone with a portable power bank rated at least 20,000 mAh
- Cash in small bills (ATMs go offline when power fails)
- Local paper maps of Scott County evacuation routes

When flooding disrupts local supply chains, having a shelf-stable food reserve is critical. This guide provides methods for long-lasting nutrition when stores are inaccessible.
Evacuation: Routes Change When Both Flooding and Wind Damage Hit Simultaneously
Davenport’s riverfront neighborhoods. Fejervary Park, the East Village, Bettendorf-adjacent corridors, can lose primary evacuation routes to both floodwater and downed trees or power lines in the same event. Identify at least two routes to higher ground before you need them, and share them with every household member. If you are evacuating north or west toward higher Scott County terrain, know which bridges across Duck Creek remain passable at various water levels, the city’s emergency management office publishes road closure information during active events.
If local authorities issue an evacuation order, do not wait for a mandatory order to leave a voluntary zone. The 2024 June event, severe storms, straight-line winds, flooding, and tornadoes in a single declaration, shows how quickly conditions can transition from watch to warning to impassable road.

Frequently Asked Questions
Iowa had a flood declaration in August 2023, does that mean Davenport faces flood risk outside spring?
Yes. The August 2023 federal flood declaration confirms that significant flooding in Iowa is not limited to spring snowmelt. Heavy convective storms in July and August can overwhelm urban drainage systems, including Duck Creek, in under an hour. Davenport residents should treat flood preparedness as a year-round posture, not a March-through-May concern.
For the year-round fundamentals behind that posture, see our Flood Preparedness guide.
Three of Iowa’s recent severe storm declarations included tornadoes. How does that affect how I shelter in Davenport?
It means your tornado shelter plan cannot default to the basement if your home is at flood risk. Identify an interior room on the highest dry floor, a bathroom or interior closet away from windows, as your fallback shelter. Know the location of the nearest community shelter before storm season, and sign up for Scott County’s emergency alert system so you receive warnings with enough lead time to make that choice safely.
Does Davenport provide sandbags, and when should I expect them to be available?
During significant river rise events, the City of Davenport typically opens sandbag distribution sites at announced locations. Monitor the city’s official website and social channels for site openings, they are usually activated when the Mississippi River approaches or exceeds flood stage at the Davenport gauge. Don’t wait for the announcement to have your own supply of sandbags on hand; keeping 20–30 pre-filled bags in a shed or garage can protect basement window wells and door thresholds in a fast-moving urban drainage event before city resources are deployed.
