The D.R. Wintermann Wildlife Management Area (WMA) is a 246-acre property near Eagle Lake, Texas, about 75 miles southeast of Houston. The property was donated to Ducks Unlimited by the D.R. Wintermann family in the mid-1990s. Subsequently, DU transferred ownership to the Texas Parks and Wildlife Department (TPWD) and assisted with converting the former agricultural lands into managed waterfowl habitat.

Though small in size, the Wintermann WMA is surrounded by thousands of acres of traditional rice agriculture, making it unique and important for resident and wintering waterfowl as well as other wildlife.

Over the years, however, the infrastructure and management capabilities of these wetlands have degraded. DU and TPWD are working together to improve the area by increasing water delivery and improving water management.
