Lake Brownwood is a reservoir on Jim Ned Creek and Pecan Bayou in Brown County, Texas, United States. After a devastating flood in 1900, the citizens of Brown County created the Brown County Water Improvement District by election in 1926. The water district acquired the land necessary and built a dam to impound the waters of Pecan Bayou at its confluence with Jim Ned Creek. The dam was completed in 1932. A record-breaking flood in July of the same year filled the lake with water. The town of Lake Brownwood, Texas formed, and the Texas Parks Board acquired land for Lake Brownwood State Park in 1933.
