Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to one hundred. [1] Under the TSI scale, water bodies may be defined as: [1] oligotrophic (TSI 0–40, having the least amount of biological productivity, "good" water quality);
Lake Buchanan, the largest of the Texas Highland Lakes. The Texas Highland Lakes are a chain of fresh water reservoirs in Central Texas formed by dams on the lower Colorado River. [1] The Texas Colorado River winds southeast from West Texas to Matagorda Bay and the Gulf of Mexico. The lower Colorado River basin has a history of major flooding.
The primary mode of informing the quality of water of rivers, lakes, streams, ponds, estuaries, coastal waters and wetlands of the U.S. is through the National Water Quality Inventory Report. Water quality assessments are conducted pursuant to water quality standards adopted by states and other jurisdictions (territories, interstate commissions ...
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
The water rights to the lake are allocated to the city of Waco and the Brazos River Authority, although the lake is owned by the United States government.
