Which formation do wells in Callender Lake draw from?

We cannot say yet for Callender Lake. This atlas assigns layers with the TWDB layered models processed so far (the Northern Trinity and Woodbine model, the Hill Country Trinity model, the northern Gulf Coast Aquifer model and the High Plains Aquifer System model), and none covers this area with enough wells. The depth, water level and yield on this page do come from the real wells here.

What a well costs in Callender Lake

At the median depth for Callender Lake (540 feet), a complete home well would cost roughly $16,000 to $39,000: $25 to $60 per foot for drilling, casing and seal, plus $2,500 to $6,500 for the pump, pressure tank, controls and hookup at the well. Across the whole middle half of depths (490 to 571 feet) the range runs from $15,000 to $41,000. This is TerraFunded's estimate from published Texas prices, not a quote, and it leaves out trenching and the line to the house. Get prices from at least two licensed drillers.

At the median depth (540 feet), a complete well would cost roughly $16,000 to $39,000, by TerraFunded's estimate from published Texas driller prices. The real price comes from a licensed driller's quote.

How deep is the water in Callender Lake?

When the wells were finished, the water stood a median 205 feet below the surface (37 wells), well above the bottom: the typical well holds about 335 feet of water. The level moves with drought and from one well to the next.

Do I need a permit to drill a well in Callender Lake?

Callender Lake is inside the Neches and Trinity Valleys Groundwater Conservation District. Groundwater conservation districts in Texas can require registering or permitting a new well, keeping set distances from property lines and other wells, and paying fees. Rules differ from district to district: ask the district before drilling.

How these numbers are made

We count new and replacement domestic (home) wells whose coordinates fall inside the place boundary or within 2 miles of it. We use the last 10 years when there are at least 30 wells; otherwise all since 2001. The median is the middle well and the middle half runs from the 25th to the 75th percentile.

These are depths of real wells drilled nearby, not a promise about any property. Groundwater can change over short distances and with drought. A licensed water well driller can tell you what to expect on a specific tract.
