Practice 4: Supplemental Water

Water is the most critical resource for wildlife survival in Texas, particularly during the state's frequent droughts. Supplemental water is one of the seven qualifying wildlife management practices, and it involves ensuring that wildlife on your property has reliable access to clean water throughout the year — especially during hot, dry summer months when natural sources may fail.

What Qualifies as Supplemental Water?

Supplemental water means providing, maintaining, or improving water sources specifically for the benefit of wildlife. This goes beyond simply having a stock tank on your property — the water sources must be accessible to wildlife, maintained in functional condition, and documented as part of your wildlife management program.

Many existing ranch water infrastructure can qualify with simple modifications. The key is ensuring wildlife access and documenting your maintenance efforts.

Supplemental Water Activities for Your Annual Report

Wildlife guzzler installation

Purpose-built water catchment systems that collect rainfall and store it for wildlife. Guzzlers are particularly valuable in arid ecoregions like the Trans-Pecos and High Plains where natural water is scarce.

Stock tank modification

Adding wildlife-friendly features to existing stock tanks — escape ramps for small animals, sloped banks for wading birds, rock or brush piles near water for cover. Fencing livestock away from a portion of the tank allows vegetation to establish.

Drip system maintenance

Solar-powered or gravity-fed drip systems that provide small, consistent water flows for birds and small mammals. Particularly valuable for quail management.

Spring development and maintenance

Clearing, protecting, and maintaining natural springs. Install collection basins and overflow routes that create micro-wetland habitat.

Trough maintenance and repair

Cleaning, repairing, and maintaining water troughs for wildlife access. Replace float valves, fix leaks, clear algae, and ensure year-round functionality.

Pond and tank water level management

Monitoring water levels during drought and adding supplemental water (trucking or pumping) when natural sources drop below functional levels.

How to Document Supplemental Water

Document every water source check with photos showing the water level, condition of the infrastructure, and any maintenance performed. Photograph repairs before and after. Track water levels over time — this creates a compelling drought-resilience narrative for your annual report. Log the date, location, condition observed, and any action taken at each water source visit.

Ecoregion Considerations

TPWD recommends a minimum of one permanent water source per 200-400 acres, depending on ecoregion. In the Trans-Pecos and High Plains, where rainfall is under 15 inches annually, supplemental water is often the most critical practice. In the Pineywoods and Gulf Prairies, water is generally abundant, but drought years can dry up seasonal sources — maintaining backup water is still important.

Other Wildlife Management Practices
