Developers help Hamilton Pool by making it easier to stand up in

Hamilton Pool is a collapsed grotto in Travis County and probably the best swimming hole in Texas. The Austin American-Statesman is reporting that an upstream housing development has polluted Hamilton Pool with silt.
Hamilton Pool and the silt-covered four-mile stretch of creek feeding it will cost about $2.3 million to clean, a consultant hired by Travis County said today. The creek and iconic southwestern Travis County swimming hole were polluted by a development along the Hays/Travis county line, according to the consultant, echoing what county officials were already saying.
The development company, Coldwater Development, has said it may not be fully responsible for the silt. The developers have also said they obtained and followed the proper permits from the state and Hays County, and that the heavy, flood-causing rains in May 2007 were more than any development could be expected to handle.
The silt now covers almost all of the four-mile stretch of creek and sits at the bottom of Hamilton Pool. The creek’s swimming holes have been filled in; one near the development was 25 to 30 feet deep before the May rains, and is now only about 5 feet deep, according to Espey Consultants.
Property rights extremists, which Texas seems filled with, argue that developers should be able to do whatever they want on their property, unencumbered by regulations. They ignore the rights of others, especially the unlucky downstream folks whose property suffers from their beliefs.
When development occurs in a creek’s watershed, and impervious cover increases, the frequent result is destruction of the creek. Erosion undermines and topples riparian trees. Aquatic life dies because of thermal, sedimentary, and chemical pollution. Water becomes unsafe for contact recreation. The natural baseflow that previously sustained the creek year-round is converted to torrential flows during storms alternating with periods of no flow at all. In the worst cases, the stream must be converted to a concrete-lined channel to speed the storm runoff downstream to the next unlucky souls.
Austin has good watershed protection ordinances that extend beyond the aquifer recharge zone. Even though they didn’t protect Hamilton Pool, it’s time San Antonio adopted some of its own, only better.
