Welcome to Texas. They, like most of Texas is in a drought, have you taken a look at Lake Travis lately? We have had a good bit of rain here in my area of West Texas, but still not enough to bring the water table up to acceptable levels. I have two springs on my place that I have never seen dry, always a pool of nice cold water about four feet deep and approximately 4-5 feeet wide by 10 feet long, it has dried to a bucketful this year. If we don't get some rain with good run-off soon they will be dry by opening day.
