Paul Knight of the Houston Press said in a 2009 article that some people blamed the development of the artificial Cedar Creek Lake, which opened in 1965, and development of the area surrounding the lake for the initial influx of crime and recreational drugs into the county and the East Texas region. Carroll Dyson, a retired pilot and Henderson County resident interviewed by the Houston Press, said in 2009 that the lake attracted "white flight" from metropolitan areas. Dyson added, "When all your rich people from Dallas and Houston move out here, the thieves are just drawn to them." Ray Nutt, the sheriff of Henderson County, said that the area around the lake has "a lot of good people," yet it was also where "a lot of criminals tend to flow."
