Lake Granbury Water Quality

Lake Granbury is a critical water supply in North Central Texas, providing water for over 250,000 people in more than 15 cities. It provides water for industrial use, including cooling water for a natural gas-fired steam electric power plant and the Comanche Peak nuclear power plant. It is also a recreation haven for local water enthusiasts. In recent years golden algae blooms have caused a number of fish kills in Lake Granbury, with substantial economic and biological losses.

North Central Texas Water Quality

Water quality in North Central Texas reservoirs is a growing concern. Five of the major reservoirs in the Trinity River basin managed by Tarrant Regional Water District (TRWD) now serve 1.6 million people across 11 counties and are expected to serve 2.66 million by 2050. The Texas Water Resources Institute, Texas Agricultural research and Extension Center - Dallas and Texas A&M Agriculture are collaborating with TRWD to study water quality protection and improvements in these five reservoirs in regard to the major problems of sediment and nutrient loading. Sediment loading affects reservoir capacity and water clarity; nutrient loading results in algae growth that impacts water treatment and recreational use.

Trinity River Basin Environmental Restoration Initiative

The Trinity River, the 512-mile river that stretches from north of the Dallas-Fort Worth Metroplex to Galveston Bay, and its natural resources are important assets to Texas. With more than 8.9 million residents, the river and its 1,983 miles of major tributaries drain an area of more than 11.5 million acres and supports water needs for 20 percent of the state's population. Many of these residents, urban and rural, depend on the river and its natural resources for maintaining quality of life and economic prosperity. Increased development and changes in land use, however, threatened the water quality, wildlife habitats, groundwater availability, recreational opportunities and flood control of the basin.
