Where are Texas aquifers?

Some water-bearing formations dip below the surface and are covered by other formations. Aquifers with this characteristic are common, although not exclusive, east and south of Interstate Highway 35. Aquifers covered by less permeable formations, such as clay, are confined under artesian pressure.

What is the largest aquifer in Texas?

How deep are the aquifers in Texas?

The aquifer is hydraulically connected to overlying alluvium along the Red River. The thickness of the aquifer ranges from a few feet in outcrop areas to about 700 feet near the downdip limit of slightly saline water in Fannin County. Maximum depth to the top of the aquifer is about 2,000 feet below land surface.

How long will the Ogallala Aquifer last?

Using less water can help save the Ogallala Aquifer. At the current rate of use, part of the Ogallala could be exhausted within this century and may take 6,000 years to restore. It is important to develop agricultural innovations to area farmers sustain agricultural production in that region.

Do I need a permit to drill a water well in Texas?

Under the Rule of Capture, a landowner needs no permit to drill a well and pump groundwater, and he may pump as much water as he may beneficially use even if that causes his neighbor’s well to go dry. He may also sell the water withdrawn from the ground for use at any location.

Are there artesian wells in Texas?

The artesian-well area is largely confined to the Coastal Plain east of the Balcones Escarpment, although there have been other isolated artesian areas, most notable of which were located at El Paso, Fort Stockton, and Balmorhea.

Is the Ogallala Aquifer running out?

Today the Ogallala Aquifer is being depleted at an annual volume equivalent to 18 Colorado Rivers. Although precipitation and river systems are recharging a few parts of the northern aquifer, in most places nature cannot keep up with human demands.

Can the Ogallala Aquifer be saved?

How many acres do you need to drill a water well in Texas?
