Dickinson Bayou runs more than 20 miles from near Alvin to Dickinson Bay on Galveston Bay, and it passes right through the city that shares its name. The town itself sits roughly 10 feet above sea level on just over 10 square miles, about midway between Houston and Galveston, with around 21,000 residents. Low ground, a tidal bayou and heavy Gulf rain add up to a place where flooding has hit the same streets more than once.

Harvey and the Bayou From Cemetery Road to Highway 3
Between August 25 and 29, 2017, the National Weather Service gauge in Dickinson recorded 43.92 inches of rain from Hurricane Harvey. The weather service reported major flooding along Dickinson Bayou from Cemetery Road past Highway 3, and published accounts describe roughly 90 percent of the city taking on water.
Bayou flooding brings a specific set of cleanup issues. Water rises slowly enough that it soaks deep into walls, then lingers before draining. Sediment settles on floors and inside wall cavities. Everything porous below the high-water mark generally needs to come out, and the structure must be cleaned and disinfected before drying. That is the core of professional flood cleanup, and skipping steps can leave odor and contamination sealed inside rebuilt walls.
Why Bayou Water Should Never Be Treated as Clean
Even in dry weather, Dickinson Bayou is on the state's list of waters that don't meet quality standards for bacteria and dissolved oxygen. In a flood, it also picks up runoff from ditches, yards and streets. Anything it touches inside a house should be handled as contaminated:
- Wear rubber boots, gloves and eye protection during cleanup
- Keep children and pets out of affected rooms
- Discard upholstered furniture, mattresses and stuffed toys that were submerged
- Throw out food, medicine and cosmetics that floodwater reached
- Wash hands thoroughly and clean any cuts right away
If water came up through floor drains or toilets, that's a sewage backup and calls for sewage cleanup with disinfection and proper disposal.
Repeat Flooding and the City's Buyout Program
Some Dickinson neighborhoods have flooded more than once. The city runs a voluntary CDBG-DR buyout and acquisition program aimed at areas prone to repetitive loss, which gives some owners in those areas an alternative to rebuilding in place. If your property has flooded before, it's worth contacting the city to ask whether it falls within the program before committing to a full rebuild.
For homeowners who stay, careful documentation matters. Photograph damage room by room, keep removed materials until the adjuster has seen them or approved disposal, and save every receipt. Flood claims usually go through a separate flood policy rather than homeowners insurance.
Bay Surge on the West Shore
Dickinson's bayou opens onto the western side of Galveston Bay, and that shoreline can take a direct hit from surge. During Hurricane Ike in September 2008, the weather service recorded surge of 10 to 15 feet along the west side of the bay. When surge pushes into the bayou's mouth while rain is falling inland, water has nowhere to go, which is why both sources matter for anyone living near the bayou or its tributaries.
Low Ground, Long Summers and Mold
Homes on low, flat ground near water stay humid, and indoor drying after a flood can take longer than people expect. Mold often appears first on the backs of baseboards, inside lower cabinets and on drywall paper behind furniture. Opening walls to the studs after floodwater, running dehumidifiers continuously and confirming dryness with a moisture meter before rebuilding all reduce the chance of growth returning. Where mold has already spread, mold remediation uses containment and HEPA filtration to keep spores out of the rest of the house.

Dickinson Water Damage Questions
My Dickinson home flooded in Harvey. Will it flood again?
There is no way to say for certain, but a home that flooded once along Dickinson Bayou faces real risk in future storms. Check your current FEMA flood zone, keep a flood policy, and ask the city whether your area is covered by its voluntary buyout program for repetitive-loss areas. Elevating utilities and using water-resistant materials during repairs can reduce damage next time.
Is it safe to clean up bayou floodwater myself?
Small amounts in a garage can be handled with care, but floodwater from Dickinson Bayou should be treated as contaminated because it carries bacteria and debris. Wear boots, gloves and eye protection, and keep children out of it. For water inside living spaces, especially if it reached drywall or HVAC equipment, a restoration provider can remove affected materials and disinfect the structure.
Where can I check flood conditions on Dickinson Bayou?
The National Weather Service Houston/Galveston office, which uses a Dickinson mailing address, issues flood watches and warnings for Galveston County. Sign up for local emergency alerts, watch rainfall forecasts during tropical events, and look up your property on FEMA's Flood Map Service Center to understand your risk.
