Before an offer near Pukwana, look at the Brule County flood zone map: FEMA's zone label affects insurance, permits and resale. Covered here for Brule County: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the District III regional GIS map.
Checking the Brule County flood zone map step by step
Out toward Cedar Grove Colony, the official source is FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. A tract near Bijou Hills without an address can still be found: search the nearest road and click inside the land.
Pulling up a parcel
Lots and tracts near Grass Ranch Colony appear on the District III regional GIS map, which opens without registering. With a lot near Cedar Grove Colony, type a street address, an owner's name or a parcel number, and the matching parcel lights up. If you're looking near Grass Ranch Colony, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Recorded documents worth pulling
For anything that matters, pull the recorded deed through the Register of Deeds; the parcel line is a drawing of it, for land near Grass Ranch Colony included. For a home near Grass Ranch Colony, bring the book and page from the tax record to skip a name search.
How land is described here
South Dakota follows the Public Land Survey System, so rural legal descriptions near Missouri River cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Bijou Hills can be irregular. Copy the legal description from the record for the parcel near Ola before you request a deed or survey.
Low spots and local drainage
Low-lying fields near Ola may not have detailed mapping, so ask neighbors about past flooding. Marshy spots near Grass Ranch Colony can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Bijou Hills, but coverage can be spotty out of town. A screenshot of the parcel near Pukwana with its ID helps when you meet an owner or agent.
Limits of the parcel data
The acreage figure is an estimate; just a licensed surveyor establishes the real lines on land around Cedar Grove Colony. On ground around Missouri River, records update in batches, so a deed recorded last month may not show yet.
Neighboring parcel maps
Brule County borders Aurora County, Buffalo County, Charles Mix County, Jerauld County, and Lyman County, and each of those keeps its own parcel map. Ground near Pukwana that runs to the line can be split in two county records, so check the neighboring map before you assume the acreage. For property near Ola, the Platbookmapper state page lists every neighboring county map across South Dakota.
A short flood checklist
If you're looking near Ola, ask the seller whether the home has flooded before closing; getting a quote early avoids surprises.
Reading A, AE and X
For a home near Cedar Grove Colony, zones beginning with A or V mark the Special Flood Hazard Area, which FEMA defines as a 1% annual chance of flooding. Out toward Grass Ranch Colony, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
A quick look at the area
Chamberlain serves as the county seat, which is where the courthouse records live. Other places on the map include Kimball, Pukwana, Bijou Hills, and Cedar Grove Colony, where town lots give way to larger tracts. Around 5,311 people live in Brule County (Census Bureau estimate, 2023) on some 817 square miles. Landmarks such as Missouri River make handy reference points on the map.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the District III regional GIS map too to confirm you have the right parcel near Pukwana.
Money questions tied to the zone
For a parcel near Missouri River, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Building or adding on near Cedar Grove Colony in a mapped zone can trigger elevation rules; ask the local floodplain administrator before you plan.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
