Looking at a lot near Lake Sumner? A quick look at the De Baca County flood zone map shows whether it sits in a FEMA flood zone, and it costs nothing to check. Covered here for De Baca County: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the NM Office of the State Engineer County Parcels 2025 layer in ArcGIS Map Viewer.
The De Baca County flood zone map: start here
For parcel-by-parcel detail, open the National Flood Hazard Layer viewer, which lets you click a spot and read its zone, which applies near Canton as much as anywhere. Vacant ground around Agudo can still be found: zoom in from US Route 84 then click the parcel area.
Getting to the right map
Property in and around Lake Sumner can be looked up on the NM Office of the State Engineer County Parcels 2025 layer in ArcGIS Map Viewer, which opens without registering. When a rural tract has no street number, pan along US Route 84 until the lines appear, then click inside the one you want, and that holds around Cardenas too. If the land is near Fort Sumner, save the parcel ID from that panel; every clerk in the county uses it to find the file.
What to request from a seller
With a lot near Lake Sumner, ask the listing agent about past flood claims before closing; getting a quote early keeps the budget honest.
A quick look at the area

Roughly 1,657 people live in De Baca County (Census estimate, 2023) spread over about 2,323 square miles. De Baca County was organized in 1917, which matters when you trace an old farm's title.
Taking the map into the field

Lining it up with the parcel map
FEMA doesn't draw property lines, so check the NM Office of the State Engineer County Parcels 2025 layer in ArcGIS Map Viewer too to see exactly which lot near Canton you're looking at.
Lenders and permits
Near Canton, an Elevation Certificate from a surveyor helps: it records the building's elevation against the base flood. New construction in a floodplain near Lake Sumner often needs a floodplain permit; ask the local floodplain administrator early.
Sections, lots and bearings
New Mexico uses the Public Land Survey System, so deeds around Cardenas reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Agudo odd-sized. Write down the legal description for the tract near Agudo for any title or survey request.
Beyond the mapped zones
Small streams around Lake Sumner may not have detailed mapping, so look for water marks and debris lines. Marshy spots near Fort Sumner can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
