Lake Livingston is the second largest reservoir wholly within the State of Texas. It was created by a dam constructed on the Trinity River near the cities of Coldspring and Livingston in San Jacinto and Pol Counties, respectively. The dam was completed in September, 1969. The resulting impoundment inundated approximately 82,250 acres located in Poly, San Jacinto, Trinity, and Walker Counties, and created 460 miles of lake shoreline in this previously lakeless East Texas region. This report is concerned with the area generally within 2,000 feet of the 131 foot contour line of Lake Livingston. In the presentation of a wastewater treatment plan for this area, the historic development of the area is evaluated, future development is projected, and the feasibility of alternate wastewater treatment programs is assessed. The impact of Lake Livingston on the economic and demographic character of this four-county region began in the early 1960's when the creaion of the lake was announced. By 1969, when the dam was completed, well over 10,00 new subdivision lots had been platted. By the end of 1972, when this study was conducted, there were over 90 subdivisions in existence and close to 26,000 lots had been platted. However, only 6.7 percent of these lots were occupied by dwelling units. This study projects that by 1990, 40 to 50 percent of the lots will have dwelling units. This will represent about 16,000 residences or 46,400 potential habitants. However, only 10 to 15 percent of those dwelling units are projected to house permanent residents. The remainder of the dwelling units will be seasonal or weekend homes. A study of the soils in Lake Livingston area revealed that most of the area is unsuitable for septic tank usage. Even those regions which are suitable for limited septic tank usage will be inadequate to support the density of development which is projected to occur in the Study Area.
