Sam Rayburn Reservoir is a man-made lake on the Angelina River in Texas. It was constructed in the mid-20th century for flood control, hydroelectric power generation, and water supply. The reservoir is named after Sam Rayburn, a former Speaker of the House of Representatives.
The reservoir has a storage capacity of 3,997,600 acre-feet, making it the largest lake entirely within the state of Texas. It is fed by several creeks and streams, including the Angelina River, which provides 90% of the inflow. The lake is also supplied by surface runoff and snowmelt during the winter months.
The primary agricultural use of the reservoir is for irrigation, with many farmers in the surrounding area relying on it for their crops. Additionally, the lake is a popular recreational destination, with activities such as fishing, boating, and swimming drawing visitors from across the state.
