What is non-point source pollution?

Non-point source pollution are harmful substances that occur as a result of human activities over a wide area rather than from one specific location. These include forms of diffuse pollution caused by sediment, nutrients, organic and toxic substances that wash off city streets, plowed fields or other developed areas. The pollution is carried to lakes and streams by runoff.  Examples of non-point source pollution are oil and gas that leak from cars and trucks onto the pavement or over applicaton ...

Why are some lakes/rivers clearer than others?

There are a number of factors that may affect water clarity.  The chief factor in the clarity of lakes and rivers in Texas is sediment. The more sediment in a stream or body of water, the cloudier it appears. This factor can vary depending on geography and climate. Some areas naturally have more sediment drawn from the surrounding land, particularly agricultural areas, where soil is often broken up and exposed. Water tends to be cloudier during rainier seasons when runoff carries topsoil and oth...

What are invasive plants?

Invasive plants are non-native, typically exotic plants that thrive when introduced into areas where they have no predators or disease control. They quickly reproduce and grow unchecked, crowding out native species that use the same habitat. Some examples of invasive plants in Texas include the Chinaberry tree, running bamboo and kudzu vine.Invasive water plants have a direct impact on Texas lakes.  Plants such as giant salvinia, a floating plant native to Brazil, is especially harmful as it gro...
