The Galveston Bay Watershed

Galveston Bay is an estuary- a place where salt water and fresh water meet. Galveston Bay is surrounded by human development. Oil refining and transport, fisheries (fish, oyster, shrimp), Import/Export (Port of Houston). Recreation and Tourism. Major tributaries- Trinity river, San Jacinto river, Houston Ship Channel, Clear Creek, Goose Creek. Characteristics

Water pollution- petrochemical industry waste, ships dumping trash, oil spills, power plant effluent, organic pollution from urban sewage and trash, agricultural pollution from pesticides and fertilizers. Overfishing- oystering, shrimping and fishing is regulated. Loss of wetland habitats- 90% of coastal marshes have been lost due to development. Human Overpopulation Problems

Solutions Laws to regulate industry- Clean Water Act, Monitoring Wetland Restoration- Marsh Bash Regulation on the Fishing industry- length of shrimping season. Educaton- Bay Day Activism- Galveston Bay Foundation. Human Population Stabilization. Solutions

Irrigation- farming irrigation is the #1 use of water nationwide Industrial use- power plants, refineries, etc. Commercial use- hotels, stores, malls, etc. Community use- homes Recreational use- fishing, surfing, skiing, swimming, boating Water Use in Texas

Surface water- lakes and reservoirs. Example: Lake Houston Aquifers- large underground areas of gravel, sand and rock where water is stored. Example: Edwards Aquifer(San Antonio, Austin) Water sources in texas
