Brown County's experience of the 20th century was shaped in part by a catastrophic 1900 flood along Pecan Bayou, which fed political will for a reservoir project through three decades of competing upstream and downstream interests. The State Board of Water Engineers authorized construction on December 3, 1929, and the dam followed shortly after.
The Civilian Conservation Corps — the New Deal employment program that built much of the Texas state park system — developed Lake Brownwood State Park between 1934 and 1942. The 537.5-acre park opened in 1938, a few years before Pearl Harbor redirected the CCC's labor elsewhere. The park and Flat Rock recreation area remain managed by the Brown County Water Improvement District.
Flat Rock sits on the lake's south shore, near the former channel of Pecan Bayou. The bayou — the waterway whose flooding prompted the reservoir project — now runs beneath several feet of lake water at high pool. Its original course is invisible from the surface, but the bottom terrain reflects it: irregular depths, submerged obstacles, variations in current that affect the boat ramp's behavior in ways that surprise visitors unfamiliar with the lake's hydrology.
Several drowning incidents have occurred in the swimming area near the Flat Rock boat ramp over the lake's history, though specific counts are not publicly documented by park management.

The legend attached to Flat Rock predates the lake itself. Before the reservoir was filled, Pecan Bayou ran through the valley; local oral tradition holds that a young girl drowned in the bayou, and that her presence remained after the water rose.
Boaters using the Flat Rock ramp have reported unexplained difficulties loading and unloading — resistance, unexpected hull damage consistent with striking a large submerged object, though no such object is located near the ramp. Lake users have attempted to explain this through the hydrology of the flooded bayou channel beneath, though the same conditions do not seem to affect other ramps on the lake in the same way.
The child's presence is most consistently reported after dark. Residents in lakefront homes near Flat Rock have described hearing the sound of a child laughing coming from the water when no one is present. One account, documented on local paranormal sites, involves a witness watching a small girl run the full length of their dock and jump into the water — and finding nothing when they reached the end of the dock.
The lake has experienced multiple drowning incidents in the Flat Rock swimming area over its operational history, adding a documented layer of tragedy to the site's reputation.
