Another significant source of water in Texas is surface water, which comes from lakes and rivers. Texas is home to many major rivers, such as the Rio Grande, the Brazos River, and the Colorado River, as well as numerous lakes, including Lake Travis, Lake Buchanan, and Lake Amistad.
Surface water is collected through reservoirs and dams, which help regulate its flow and provide a stable water supply. This water is then treated and distributed to meet the needs of communities, agriculture, and industries across the state.
Reused and Recycled Water
In recent years, Texas has been exploring innovative solutions to address water scarcity by promoting the reuse and recycling of water. This involves treating wastewater and using it for non-potable purposes such as irrigation, industrial processes, and even replenishing aquifers.
The Texas Water Development Board encourages the use of recycled water to reduce reliance on freshwater sources and ensure a sustainable water future for the state.
According to the Texas Water Development Board, about X% of Texas’ water supply comes from groundwater sources, X% from surface water sources, and X% from recycled water sources. It’s important to note that the availability of water from these sources can vary depending on factors such as drought conditions, population growth, and the overall demand for water in the state.

Regional Water Supply Systems
When it comes to water supply, Texas has implemented various regional systems to ensure a steady and reliable source of water for its residents. These systems are designed to distribute water efficiently across different regions of the state, taking into account factors such as population density, geographical features, and available water sources.
Water Distribution in East Texas
In East Texas, the primary water distribution system is managed by the Sabine River Authority. This authority is responsible for managing the water resources of the Sabine River Basin, which spans across 32 counties in East Texas.
The Sabine River, along with its tributaries, provides a significant portion of the water supply for this region. Additionally, there are numerous reservoirs and lakes that serve as important water sources for both residential and agricultural needs.
Water Distribution in Central Texas
Central Texas relies on the Colorado River as its main water source. The Lower Colorado River Authority (LCRA) plays a crucial role in managing and distributing water in this region. The LCRA operates a system of dams and reservoirs along the Colorado River, which help to store and regulate the flow of water.
The water from the Colorado River is then distributed to various cities and communities in Central Texas through a network of pipelines and treatment plants.
Water Distribution in West Texas
West Texas faces unique challenges when it comes to water supply due to its arid climate and limited water resources. The primary water source for this region is the Ogallala Aquifer, one of the largest underground water reservoirs in the world.
The High Plains Underground Water Conservation District is responsible for managing and conserving the water resources in this area. However, due to the decreasing water levels in the aquifer, West Texas has been exploring alternative water sources such as desalination and water reuse to meet its growing water demands.
Water Distribution in South Texas
In South Texas, the Rio Grande serves as the main water source for both Texas and Mexico. The International Boundary and Water Commission (IBWC) is responsible for managing and allocating the water resources of the Rio Grande.
The water from the Rio Grande is used for various purposes, including irrigation, industrial use, and residential consumption. Additionally, South Texas also relies on groundwater sources, such as the Edwards Aquifer, to supplement its water needs.
It is important to note that these regional water supply systems work in collaboration with local water utilities and municipalities to ensure a reliable water supply for the residents of Texas. Through effective management and conservation practices, Texas continues to meet the water needs of its growing population.
The Role of Reservoirs and Aquifers
When it comes to providing water for its vast population and diverse industries, Texas relies on a combination of reservoirs and aquifers. These natural resources play a crucial role in ensuring a steady supply of water throughout the state.
Major Reservoirs in Texas
Texas is home to numerous major reservoirs that serve as vital water sources. These reservoirs, such as Lake Texoma, Lake Travis, and Lake Livingston, are man-made bodies of water created by damming rivers.
They not only provide water for drinking and irrigation but also play a significant role in flood control and recreational activities.
One of the largest reservoirs in Texas is the Lake Sam Rayburn Reservoir, situated in the eastern part of the state. With a surface area of over 114,000 acres, it is a popular destination for fishing and boating enthusiasts.
Another notable reservoir is the Toledo Bend Reservoir, which is shared with Louisiana and covers an impressive 185,000 acres.
Ogallala Aquifer
The Ogallala Aquifer, also known as the High Plains Aquifer, is one of the most important underground water sources in Texas. It stretches across eight states, including a significant portion of the Texas Panhandle.
The aquifer provides water for various purposes, including agriculture and municipal use.
Unfortunately, the Ogallala Aquifer is facing challenges due to excessive pumping and depletion. As a result, water conservation efforts and sustainable management practices are crucial to ensure its long-term availability.
Edwards Aquifer
The Edwards Aquifer is another significant groundwater source in Texas, supplying water to a large population in the central and southern parts of the state. It is a complex system of interconnected limestone formations that store and transmit water.
The aquifer is known for its unique ecosystem and provides water not only for human consumption but also for numerous endangered species and sensitive habitats. Due to its ecological importance, the management of the Edwards Aquifer involves balancing human needs with the preservation of the natural environment.
