What should I know about creeks, springs and seasonal water when buying a farm or ranch?

Perennial vs seasonal water

One of the first things to determine is whether a creek or spring flows year-round or only after rain:

• Perennial creeks and springs flow throughout the year, even during dry periods. These are valuable as reliable water sources for livestock and wildlife, but they are less common in Northeast Texas than seasonal water features.
• Seasonal (intermittent) creeks flow only after rainfall or during wet seasons. They may appear as dry creek beds for much of the year. A seasonal creek can still provide significant drainage, erosion control benefits, and occasional water for livestock, but it should not be relied upon as a primary water source.
• Springs emerge where groundwater reaches the surface. Some springs flow consistently; others weaken or dry up during drought. A spring that looks reliable during a spring visit may not be as productive in late summer.

Drainage, flooding and erosion

• Drainage patterns. A creek defines the drainage pattern for the surrounding land. Understand where water comes from and where it goes. Changes upstream can affect flow downstream.
• Flooding potential. Creeks and low-lying areas along waterways are often in floodplains. Check the FEMA floodplain map for the property and ask the seller about any history of flooding.
• Erosion. Creek banks can erode over time, especially during high-flow events. Erosion can affect fence lines, building sites, property lines, and access roads. Look for active erosion, undercut banks, and areas where the channel is changing course.

Livestock access and fencing

• Access to water. If you plan to use the creek as a livestock water source, consider how animals will access it. Steep banks, muddy approaches, and deep channels can be dangerous. You may need to create managed access points or fence off the creek and use alternate watering systems.
• Fencing along creeks. Many properties require fencing along creeks to keep livestock from damaging banks or straying. In some cases, deed restrictions or conservation programs may require buffer zones or fencing setbacks. See our guide on evaluating fencing for more details.
• Crossings. If a creek runs through the property, you need a crossing to move livestock and equipment from one side to the other. Evaluate the existing crossings for safety and durability. Low-water crossings may become impassable during heavy rain.

Legal considerations regarding water

A visible creek or spring on a property does not mean you have unrestricted rights to use the water. Texas water law is complex and divides water into different categories with different ownership and use rules:

• Surface water in a defined watercourse. Under Texas law, water in a creek, river, or natural stream with defined bed and banks is owned by the state and managed by the Texas Commission on Environmental Quality (TCEQ). Landowners may generally use this water for domestic and livestock purposes without a permit, but other uses require a state water right permit.
• Diffused surface water. Water that runs over the land surface before entering a defined channel is owned by the landowner and may be captured and used without a permit.
• Springs. When groundwater emerges from a spring, it generally becomes surface water subject to state regulation. The specific legal treatment depends on the site conditions.
• Boundaries and property lines. A creek may form a property boundary, but the exact boundary line may not be where the water flows. In Texas, property boundaries along waterways can follow different rules depending on the type of waterway and the legal description in the deed.

This is not a legal conclusion about water rights for any specific property. For specific guidance on water rights, property boundaries, and permitted uses, consult a qualified water rights attorney and the TCEQ. See our related guide on ponds and water sources on ranch property.

Maintenance and practical considerations

• Debris and beaver activity. Creeks can accumulate debris, fallen trees, and sediment. Beaver activity can alter water flow and cause flooding.
• Upstream and downstream neighbors. What happens upstream affects your property. What you do affects downstream neighbors. Consider drainage relationships with adjacent landowners.
• Recreational value. Creeks and springs can provide excellent recreational opportunities including fishing, wildlife viewing, and aesthetic enjoyment. This value is real but hard to quantify.
• Ask the seller. How often has the creek gone dry in recent years? Has the spring always flowed? Have there been flooding issues? Have adjacent landowners made changes that affected water flow?
