Change is just about the only constant in the area that is now the north shore of Lake Travis. The limestone, gravel, clay, and loam that make up the land have evolved under the influence of wind and the mighty floodwaters of the untamed Colorado River. Comanche Indians and other tribes lived here long before settlers arrived from back east. Land grants helped many pioneers settle in the area, and their descendents benefited from electricity brought here through the Rural Electric Administration. Gradually the rural farming and ranching community developed into incorporated cities with a state-of-the art education system. The Mansfield Dam transformed a small section of the Colorado River into Lake Travis and enabled fishing and water sports. In spite of this growth, however, the north shore of Lake Travis still retains its small-town feel. Change continues, and the flora and fauna, rocks and hills, and ranches and communities that make up this beautiful part of the hill country still draw people of all ages.

This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

The Colorado River, running through Austin, Texas, and the area now referred to as Lake Travis, has always been a beautiful place to live. The early settlers found it suitable for farming and ranching--until it rained. The rain soaked up soil, and water upstream often engorged the land and washed out everything in its path. Pres. Franklin D. Roosevelt's New Deal created agencies that constructed hydroelectric dams for the Tennessee Valley Authority, and those were used as blueprints for the Lower Colorado River Authority. The ground-breaking for the Mansfield Dam took place on February 19, 1937, and the dam was completed in 1942, providing power and flood control for the area. The dam created Lake Travis and brought about a new recreational industry. Boat docks, lodges, and parks sprang up along the newly created lake, and they are still enjoyed today.
