Planning and environmental management divisionís 2012 river study under wayFor the third year in a row, the Trinity River Authorityís planning and environmental management division has embarked on a series of studies in an effort to gain a detailed understanding of the main stem of the Trinity River.
This year, Webster Mangham, TRAís manager of special studies and assessments, and Kelly McKnight, PEMD support technician, teamed with the Texas Water Development Board to establish four long-term monitoring sites in the river starting at Rosser, Texas, and continuing downstream to a point near the headwaters of Lake Livingston. These benchmarks will be used to track changes in several physical characteristics of the river over time.
This study will be important for addressing the requirements of Senate Bill 3, legislation establishing environmental flow standards to assure sufficient water to provide for a sound ecological environment in Texas streams, rivers, estuaries and bays.
Between July and October of this year, PEMD staff also will collect biological data in support of the Texas Instream Flow Program to determine the types and quantities of fish and other aquatic animals at six different sites between the East Fork of the Trinity River and Lake Livingston.
