Edwards AquiferLocated in South Central Texas, the Edwards Aquifer incorporates an area of approximately 4,350 square miles that extends into parts of 11 counties..

How many major aquifers are in Texas?

9 majorAbout 60 percent of the approximately 16 million acre-feet of water used yearly in Texas is derived from underground formations that make up 9 major and 22 minor aquifers (for map of minor aquifers, click).

Is there a water shortage in Texas?

In 2020, Texas faces a potential water shortage of 4.8 million acre-feet in a drought of record. In 2070, that number grows by approximately 87 percent to 8.9 million acre-feet (Table 7.1).

Who owns groundwater in Texas?

Who Owns the Groundwater? Landowners in Texas own the water beneath their property. See Texas Water Code Section 36.002. Moreover, recent case law makes clear that a landowner owns not only the water that emerges from the ground, but the water in place underground as well.

Which US state has the largest aquifer?

The Ogallala Aquifer is the largest aquifer in the United States. It is part of the High Plains aquifer system, which underlies parts of eight states from Texas to South Dakota.

How deep is the Paluxy aquifer?

The thickness of the Paluxy Formation varies considerably, from about 400 feet in the northern. part of the study area to less than 100 feet in the southern part (Nordstrom, 1982).

What is the largest underground source of water in Texas?

Ogallala aquiferThe massive Ogallala aquifer accounts for 90 percent of the total water in all the Texas aquifers.

Why are aquifers important in Texas?

Aquifers are an important source of water for humans, supplying about 60% of the water we use. Most of the water pumped from aquifers goes to agriculture to irrigate food crops. Over 80% of the irrigation water used in Texas comes from one aquifer, the Ogallala.

How deep is the Trinity Aquifer in Texas?

The water-bearing units are composed predominantly of limestone and dolomite of the Edwards Group and sands of the Trinity Group. The saturated thickness of this aquifer system increases from less than 100 feet in the north to greater than 800 feet down-dip to the south.

How does West Texas get water?

Much of the state’s $100 billion agriculture industry is located here. However, West Texas agriculture relies heavily on groundwater for irrigation, which comes mainly from the Ogallala Aquifer.

What happens if the Ogallala aquifer dries up?

What Happens When The Massive Ogallala Aquifer Becomes Depleted? Due to agricultural pumping and resulting depletion of the Ogallala Aquifer, the White River no longer maintains a spring-fed base flow and, today, Silver Falls is often dry and overgrown with vegetation.

What is saturated thickness?

Definition: Saturated thickness is the vertical thickness of the hydrogeologically defined aquifer in which the pore spaces of the rock forming the aquifer are filled (saturated) with water.

What are the 3 types of aquifers?

Read this article to learn about the following four types of aquifers, i.e., (1) Unconfined Aquifer, (2) Perched Aquifer, (3) Confined Aquifer, and (4) Leaky Aquifer or Semi-Confined Aquifer.

What is the majority of water used for in Texas?

The largest category of water use in Texas is for irrigated agriculture at 58 percent of the state’s water use (Table 1). Second to irrigation is the municipal sector at 28 percent, which is composed of residential, institutional, and commercial water use.
