Texas Department of Public Transportation CEO Phil Wilson has been called a "problem solver" by current members of the Lower Colorado River Authority Board. As LCRA’s new General Manager, he’ll need to be just that as the Board has recently voted to stop the flow of water headed downstream from Lakes Travis and Buchanan to Texas’ rice farming region for the third year in a row. 

Half of Texas is experiencing drought conditions, and for the third year in a row, rice farmers in Central Texas may be cut off from water supplies because of severe drought.

The Lower Colorado River Authority has asked the state to approve emergency plans to cut water to farmers in 2014 if reservoir lakes are at less than 55 percent capacity. The lakes are currently 36 percent full.

Homes and businesses would also face water restrictions.

Matagorda is just another small Texas town, but its bay is one of the key areas in the state for oyster harvesting and processing. It’s also where the mouth of the Colorado River feeds into the Gulf of Mexico, which creates a unique habitat for animals that survive within a careful balance of fresh and salt water.

The area has been hit hard in recent years by drought, and the lack of rainfall has also taken its toll on the aquatic life, whose survival depends on the fresh water to lower the salinity levels of the bay, which is where shrimp hatch and oysters reproduce.
