Wells around Ravenna draw mainly from the Cretaceous Woodbine Formation, the principal residential aquifer across Fannin County. The Woodbine reaches the surface (outcrops) in a broad band running roughly parallel to the Red River and tilts down to the southeast, so the depth to productive water depends sharply on where your property sits relative to that band. Ravenna sits in the northern part of the county near that outcrop band, north of Bonham toward the Red River. Along the river corridor, the river-laid Red River alluvium can serve as a localized shallow source on the right site. The deeper Trinity Group — here the Antlers Formation — underlies the area but is generally too deep for a home well.

Fannin County Permit Requirements

Well construction in Ravenna and throughout Fannin County is regulated by the Red River Groundwater Conservation District (RRGCD). A permit is required from the district before drilling begins, and construction must comply with TDLR standards for casing depth, grouting, and well completion. The RRGCD also requires a completion report following construction. See our guide to Fannin County water well regulations for the complete permit checklist.

Frequently Asked Questions

What formations supply well water in the Ravenna area?
Wells in Ravenna and northern Fannin County draw mainly from the Woodbine sandstone, the county's principal residential aquifer. The Woodbine reaches the surface (outcrops) in a broad band running roughly parallel to the Red River, and Ravenna sits near that band north of Bonham. Along the Red River corridor, the river-laid alluvium can be a localized shallow source as well. The deeper Trinity Group — here the Antlers Formation — lies well below and is generally too deep for a home well.
How deep are water wells drilled near Ravenna?
There's no single typical depth across Fannin County — it varies sharply with where a property sits relative to the Woodbine outcrop band along the Red River. Ravenna sits near that band, so productive Woodbine can be within reach at moderate depth, while farther east the Woodbine deepens toward the eastern county line. We review the driller's logs from neighboring wells before recommending a target depth.
What does well drilling cost in Fannin County?
Drilling rates near Ravenna typically run $28–$40 per foot — the sandy Woodbine formations here are less expensive to drill than the limestone counties to the west. Total cost depends on completion depth and the full system (casing, pump, pressure tank). We provide a free itemized written estimate after reviewing neighboring driller's logs for your parcel.
Is there a groundwater district in Ravenna?
Yes. Fannin County is within the Red River Groundwater Conservation District (RRGCD). All new wells require a permit from the RRGCD before drilling begins. DFW Well Service handles permit applications as part of every new well project.
Is water quality good in Ravenna-area wells?
Woodbine wells in Fannin County generally produce usable water, but iron and manganese are common concerns — the upper Woodbine zone has documented iron content, and outcrop areas can have excessive iron. Hardness, sulfate, and total dissolved solids that rise below about 1,500 ft of well depth are also worth testing for. We conduct water quality testing on all new wells and can recommend filtration or treatment based on results.
Is the well water in Ravenna salty or brackish?
Mostly fresh. The Woodbine around Ravenna is fresh along its outcrop band (where the sand reaches the surface), though it grows saltier below about 1,500 feet and toward the east, per Texas Water Development Board data. Iron is a more common issue than salt here — budget for an iron and total-dissolved-solids test (total dissolved solids being a measure of how mineral-heavy the water is).
