The geologist who claimed his study shows there is plenty of water in that well probably did a pump test. That is a standard test but often misleading in karst. In this case, there is a good chance, based on what I know of the area, that the well hit a relatively large conduit that stores a lot of water. The pump test may be showing a high yield because it was primarily tapping water stored in the conduit. If the test went long enough, the test might reveal that when the conduit is drained, the rate of its replenishment through fractures might be insufficient (during periods without substantial rainfall) for the planned needs of the housing development. However, if the conduit is carrying water recharged directly by the Little Blanco River, then the well potentially could provide the estimated yield in the long run - at least as long the Little Blanco keeps flowing.

The journalist made a few leaps here and there (for example, I never said the salamander population in question is a subspecies) but he got the gist of it. http://sacurrent.com/news/story.asp?id=67408 Andy Andrew G.
