The Tree Problems Dell Rapids Property Owners Face
Flood-Stressed Trees That Look Fine
Trees that went through high water rarely die that year. They decline in year two or three, by which time nobody connects it to the flood. This is the most under-diagnosed tree problem in town.
River Corridor Trees Along the Big Sioux
Bank scour undercuts root plates from the water side while the tree looks untouched from the garden. Fast riparian growth also produces weak wood that sheds limbs without warning.
Ash Concentrated Where It Is Most Stressed
Green ash was planted heavily along the river because it tolerates wet ground. It is also what emerald ash borer kills, so those trees carry both problems at once.
Old-Growth Trees on Established Streets
Dell Rapids has genuinely old residential streets with large mature canopies, decades of accumulated deadwood, and decay pockets nobody has assessed.
When the Big Sioux Floods, Trees Die Two Years Later
In 2019 the Big Sioux River below Dell Rapids rose 0.2 feet above its previous record, which had stood since 1969. That was one of two flood events that year: rain falling on snow in mid-March, then 3 to 8 inches of rainfall on the night of 11 September that produced major to record flooding across the basin.
Here is the part almost nobody knows. A flooded tree usually does not die that year. It leafs out the following spring looking completely normal, running on energy it stored before the water arrived. The decline shows up in year two or three, and by then the homeowner has long stopped connecting it to the flood.
What standing water actually does
- Root asphyxiation. Roots need oxygen from air pockets in the soil. Saturated ground for more than about a week starves them, and fine feeder roots die first. The tree loses its ability to take up water, which is why a flood-damaged tree often shows drought symptoms in a wet year.
- Silt burial. Flood water drops sediment. Several inches of new silt over the root flare puts the trunk base permanently in damp soil, and bark rots at the soil line over the following seasons.
- Bank scour. Moving water undercuts the root plate on the river side. The tree looks untouched from the garden while a third of its anchorage has been washed out.
- Delayed decline. Thinning canopy, small pale leaves, dieback starting at the top, and shoots sprouting from the trunk base. All of it shows up one to three years after the water has gone.
Which trees survive flooding and which do not
| Tolerant of flooding | Poorly tolerant |
|---|---|
| Silver maple | Sugar maple |
| Cottonwood | Linden / basswood |
| Willow | Spruce and pine |
| Green ash | Birch |
| Hackberry and boxelder | Most conifers |
Note the awkward one: green ash tolerates flooding well, which is exactly why so much of it was planted along this river. It is also the species emerald ash borer kills. A river-corridor ash in Dell Rapids is carrying both problems at once.
If you have trees within reach of high water and something looks off, the flood is worth considering as the cause even if it was years ago. Removals in the river corridor need access planned in advance, because the ground stays soft long after the water drops.
The Dell Rapids Rubble Site: What It Takes and What It Costs
Dell Rapids runs a state-licensed rubble site rather than a simple yard waste drop, and it is the only one in the area that charges a fee. It also takes far more than branches.
| Tuesday & Thursday | 1:00 pm to 6:00 pm |
| Saturday | 9:00 am to 4:00 pm |
| Season | Seasonal, closes over winter |
| Who | City of Dell Rapids residents only |
| Fees | Charged per load. Current rates are published by the city, see the link below. |
Accepted: trees, branches, grass, leaves, yard and garden waste, untreated wood, construction and demolition debris, sheet rock, plaster, concrete, carpet, furniture, mattresses and large appliances.
The city also runs free rubble site days each spring, usually a few dates in early May. Worth watching for, because a spring clean-up timed to those dates costs nothing.
Three-days-a-week access and a site that accepts demolition debris makes Dell Rapids the easiest town in the area to handle small jobs yourself. Where it stops working is volume and trunk size. Because the site charges by the load, several trips adds up quickly against having a crew take it all in one go. Everything we cut leaves with us at no separate charge.

Storm Exposure and Emerald Ash Borer in Dell Rapids
The 25 July 2026 storm
The severe thunderstorm line that crossed the area on the evening of 25 July 2026 produced 92 mph in Tea, 82 mph near Harrisburg, 72 mph at the Sioux Falls airport and 69 mph in Brandon. No dedicated National Weather Service reading was taken in Dell Rapids, which sits north of those measurement points.
Without a local number, you judge the trees. What matters here is that Dell Rapids trees carry a specific vulnerability: any tree that went through the 2019 flooding has a compromised root plate whether it looks it or not. Flood-weakened anchorage plus high wind is how a healthy-looking tree ends up on a roof. Check for soil lifted or cracked in a ring around the trunk base, a new lean measured against a fence post, hung-up limbs in the canopy, and fresh splits where two large branches meet.
Emerald ash borer
Dell Rapids is in Minnehaha County, inside the South Dakota EAB quarantine covering Minnehaha, Lincoln, Turner and Union counties. Ash wood and firewood cannot leave the county and must be shredded, buried or burned on site.
The river corridor makes this worse than average. Green ash was planted heavily along the Big Sioux precisely because it tolerates wet ground, so Dell Rapids has a concentration of ash exactly where the trees are already stressed. A flood-weakened ash has less capacity to defend itself against borer attack, and less capacity to move treatment product if you do inject it.

Deadwood removal on mature street canopies, and crown work on riparian species that shed limbs. ANSI A300 standard. We do not top trees.
Stump Grinding in Dell Rapids
Ground 8 to 12 inches below grade with surface roots included. Where flood silt has raised the grade we grind to the original soil line, not the new one.
EAB Treatment in Dell Rapids
Licensed trunk injection on a two-year cycle. On a flood-stressed ash we will tell you honestly whether the tree can still move the product around.
Storm Damage Cleanup in Dell Rapids
Full cleanup plus written documentation and photographs for your insurer. Flood-weakened anchorage means Dell Rapids trees fail at lower wind speeds than they should.

Why Dell Rapids Property Owners Call Us
We Recognise Flood Decline
A tree dying three years after high water looks like a mystery unless you know what to look for. Root asphyxiation, silt burial and bank scour all present differently, and all get missed.
Twenty Years in Minnehaha County
We work Dell Rapids, Garretson, Brandon, Crooks and Sioux Falls. We are not an out-of-town crew that appears after a storm.
Licensed and Fully Insured
South Dakota has no mandatory state licence for tree work, so the certificate is the only real filter. Ask for ours and ring the insurer directly.
Written Estimates, On Site
We come out, look at the tree and put it in writing. River corridor access cannot be judged from a photograph and neither can a compromised root plate.
We Do Not Top Trees
Topping strips structure and forces weak regrowth. On a tree with flood-damaged anchorage that is the worst combination available.
Complete Cleanup, Nothing Left Behind
The Dell Rapids rubble site charges by the load and is open three days a week. Everything we cut leaves with us at no separate charge, and the ground gets raked before we go.

Can flooding kill a tree years after the water has gone?
Yes, and it is the most commonly missed cause of tree decline in Dell Rapids. A flooded tree usually leafs out normally the following spring using stored energy, then declines in year two or three. Saturated soil starves roots of oxygen and kills the fine feeder roots, so the tree loses its ability to take up water. The symptoms look like drought stress, which is confusing because the cause was too much water.
What should I look for on a tree that went through high water?
Thinning canopy with small pale leaves, dieback starting at the top of the tree, shoots sprouting from the trunk base, and several inches of flood silt covering what should be a visible root flare. On river-side trees also check whether bank scour has undercut the root plate, because a tree can lose a third of its anchorage and look completely untouched from the garden.
Which trees handle Big Sioux flooding best?
Silver maple, cottonwood, willow, green ash, hackberry and boxelder tolerate periodic flooding well. Sugar maple, linden, birch and almost all conifers including spruce and pine do not. The awkward part is that green ash tolerates wet ground, which is why so much of it was planted along the river, and it is also the species emerald ash borer kills.

The Dell Rapids rubble site is open Tuesdays and Thursdays 1:00pm to 6:00pm and Saturdays 9:00am to 4:00pm, seasonally, for City of Dell Rapids residents only. It accepts trees, branches, grass, leaves, untreated wood and construction debris. There is a charge per load, and the city also runs free rubble site days each spring.
