The Mississippi River gauge at Rock Island Lock & Dam 15 — the RCKI2 gage — has now broken its own record twice in a generation. On July 9, 1993, the river crested at 22.63 feet during the Great Flood of 1993. On May 2, 2019, it crested at 22.70 feet, breaking that record, and sat at major flood stage for 41+ days — during the same event a temporary flood wall failed across the river in Davenport. Rock Island sits on the Mississippi at the confluence with the Rock River, with Arsenal Island in the channel at the city's edge. What the floodwaters meet here is one of Illinois' oldest housing stocks: the Broadway Historic District's Victorian homes carry a median year built of 1910, the Keystone neighborhood holds early-1900s-to-1950s homes including Sears kit houses, and many carry deferred maintenance — original windows, old roofs, aging mechanicals. A USACE flow-frequency study found many communities between Dubuque and St. Louis have seen most of their top-10 flood crests in the past 20 years; at this gage the 2001 (22.33), 2008 (21.49), and 2014 (20.90) crests all belong to that run.

Our Rock Island restoration process
- Call (773) 200-3228 — river or roof, tell us what you're seeing. Mississippi overbank, Rock River backup, storm-torn roofing, or a burst line in a 1910 Victorian — the source sets the crew and the equipment we roll with.
- Assess source, category, and historic materials. We determine whether the water is river flood, storm runoff, sewage, or clean supply water, and we plan drying around the plaster, old-growth framing, and original woodwork that define this housing stock.
- Extract and contain. Standing water is pumped out fast; contaminated water gets containment and full PPE from the first minute, and unaffected rooms are protected while we work.
- Dry with daily verification. Air movers and dehumidifiers run against moisture-mapped targets — older homes with deferred maintenance dry slowly and need patience, not speed — until meters confirm every material.
- Treat, rebuild, and document. Flood- and sewage-contacted surfaces are disinfected, mold is remediated to IICRC standards, damaged finishes are restored to pre-loss condition, and the full photo and moisture file goes to your adjuster.
Common causes of water damage in Rock Island
- Mississippi River flooding. The shared RCKI2 crest table: 22.70 ft (May 2, 2019, all-time record), 22.63 ft (July 9, 1993), 22.48 ft (April 28, 1965), 22.33 ft (April 25, 2001), 21.49 ft (June 16, 2008), 20.90 ft (July 4, 2014). The 2019 record broke 1993, with the river at major flood stage for 41+ days.
- The Milan Bottoms floodplain. Near the river, the Milan Bottoms area is floodplain and flood-insurance-sensitive — local real-estate guidance flags drainage history there even for homes that haven't flooded recently.
- Old roofs and deferred maintenance in the historic districts. The Broadway Historic District's Victorian homes (median year built 1910) and Keystone's early-1900s–1950s stock — including Sears kit houses — carry original windows, aging roofs, and worn mechanicals that admit wind-driven rain and slow a home's recovery.
- Aging laterals and inflow/infiltration. Rock Island-specific sewer documentation wasn't verifiable in our sources, but the heavily pre-WWII housing stock means aging service laterals and basement waterproofing needs are the known local theme — wet-weather backups follow heavy rain here as everywhere old lines meet new storms.
- Tornado and severe-wind damage. On April 4, 2023, an EF1 tornado (95 mph peak, 1.59-mile path) moved through Rock Island toward the Blackhawk State Park area — snapping and uprooting large trees with minor roof damage — while widespread straight-line winds to 90 mph caused significant damage across the city.
- Arctic deep-freeze pipe bursts. January 31, 2019 brought an all-time record low of −33°F at the Quad Cities station, with January 2019 also the snowiest January on record (30.2 inches) — the classic freeze-burst setup for century-old plumbing and uninsulated exterior walls.
Our Rock Island water damage services
Water extraction
Mississippi and Rock River overbank, Milan Bottoms seepage, sump failures, storm runoff, or burst pipes in century-old homes — high-capacity pumping with containment for contaminated water.
Structural drying
Monitored dehumidification calibrated for Victorian and early-1900s construction — plaster, old-growth framing, and original millwork need patient, metered drying, verified daily with moisture readings.
Mold remediation
Damp basements, wall cavities, and crawl spaces in the historic districts grow mold fast after floods. We contain, remove, and treat to IICRC standards.
Sewage cleanup
When heavy rain overwhelms aging laterals and backed-up systems, we extract category-3 water in full PPE, remove contaminated porous materials, and disinfect every surface.
Storm damage repair
Tornado- and wind-torn roofing, siding, and windows are secured, interior intrusions extracted and dried, and the structure rebuilt to pre-loss condition.

River water at the door or rain through the roof — call (773) 200-3228.
Cost factors & insurance claim help in Rock Island
No flat quotes — every Rock Island loss is scoped on its facts. River overbank is a flood-insurance matter; wind-driven rain through a storm-torn roof, burst pipes from the next −33°F snap, and sewer backups (with the backup endorsement) typically fall under homeowners coverage — and a single storm here can trigger more than one of those, so we trace and document each water source separately. Cost also turns on how long the structure stayed wet and how much porous historic material — plaster, lath, old-growth trim — must be removed and matched. We photograph and log everything and work directly with your insurance company from first call to final walkthrough.
Frequently asked questions
What are the highest Mississippi crests on record at Rock Island?
At Rock Island Lock & Dam 15: 22.70 ft on May 2, 2019 (the all-time record), 22.63 ft on July 9, 1993 (the Great Flood of 1993), 22.48 ft on April 28, 1965, 22.33 ft on April 25, 2001, 21.49 ft on June 16, 2008, and 20.90 ft on July 4, 2014. Most of the top crests belong to the past 20 years.
How long did the river stay flooded in 2019?
The Mississippi stayed at major flood stage for 41+ days, and the record 22.70-ft crest on May 2, 2019 broke the 1993 mark. During the same event, a temporary flood wall failed across the river in Davenport — a reminder of how long these events last.
What's the Milan Bottoms floodplain issue?
The Milan Bottoms area near the river is floodplain and flood-insurance-sensitive. Local real-estate guidance flags drainage history there even for homes that haven't flooded recently — if you're buying or insuring in that corridor, check the flood map before you commit.
How old are Rock Island's historic homes?
The Broadway Historic District's Victorian homes have a median year built of 1910, and Keystone's stock runs from the early 1900s through the 1950s — including Sears kit houses. Many carry deferred maintenance: original windows, old roofs, aging mechanicals. That age is exactly why drying and restoration here require old-house methods.
What happened in the April 4, 2023 tornado?
An EF1 tornado (95 mph peak winds, 1.59-mile path) moved through Rock Island toward the Blackhawk State Park area, snapping and uprooting large trees and causing minor roof damage. Widespread straight-line winds to 90 mph caused significant damage across the city the same morning.
What is Rock Island Arsenal?
The Rock Island Arsenal sits on Arsenal Island in the Mississippi River at the city's edge — one of the city's defining landmarks, alongside Augustana College, the Hauberg Estate, and the Centennial Bridge. It's a military installation, so we serve homes and businesses in the city around it, not the installation itself.
