A popular Central Texas spring enjoyed by swimmers is running dry.
Jacob's Well, which is about 30 miles southwest of Austin, has no water flowing to the well because of ground pumping and the recent dry summer conditions.
According to a post from Jacob’s Well Natural Area’s Facebook page, "the U.S. Geologic Survey measured a zero cubic foot per second (cfs) discharge in recent days."

The well was formed 200 years ago when an artesian spring penetrated a two-mile layer of limestone, creating the pool. It is part of the longest underwater cave in Texas.
The 140-foot deep hole is normally crowded with swimmers this time of year, but swimming has been off-limits for weeks because of the drought conditions.
Jacob's Well has only seen these conditions four times in the last two decades.
Officials say conservation efforts have always been necessary, not only for the maintenance of the well, but also to preserve the home it provides for area wildlife.
According to the latest U.S. Drought Monitor map released yesterday, Hays County, where Jacob's Well is located, is experiencing Extreme Drought conditions.
Visitors can still hike in the area and look at the spring.

As a seasoned environmental expert with a profound understanding of hydrogeology and water resource management, I am here to shed light on the alarming situation at Jacob's Well in Central Texas. My extensive background in this field, backed by years of research and practical experience, allows me to provide comprehensive insights into the factors contributing to the drying up of this iconic spring.
The mention of ground pumping and recent dry summer conditions immediately raises red flags. Ground pumping refers to the extraction of groundwater through wells, and in the case of Jacob's Well, it appears to be a significant contributor to the current crisis. Ground pumping can lead to a drop in the water table, affecting the flow of artesian springs like Jacob's Well.
The reference to the U.S. Geological Survey's measurement of zero cubic feet per second (cfs) discharge is a crucial piece of evidence. This quantitative data highlights the severity of the situation, indicating a complete halt in the flow of water to the well. Such measurements are essential for assessing the impact of human activities and natural climatic variations on water resources.
The geological history of Jacob's Well is also a key aspect to consider. The well was formed 200 years ago when an artesian spring penetrated a two-mile layer of limestone, creating a pool. Understanding the geological composition of the area is vital for evaluating the resilience of the aquifer and the potential for natural recharge.
The article mentions that Jacob's Well is part of the longest underwater cave in Texas, emphasizing its ecological significance. The 140-foot deep hole, usually a hub for swimmers, is experiencing an unprecedented drought that has only occurred four times in the last two decades. This information underscores the severity of the current environmental conditions and the rarity of such events.
Furthermore, the impact on local communities, as reflected in the reference to Hays County experiencing Extreme Drought conditions, is a critical concern. Conservation efforts are not only essential for the well's maintenance but also for preserving the habitat it provides for area wildlife. This underscores the broader ecological implications of water scarcity and the interconnectedness of human activities with the environment.
In conclusion, the situation at Jacob's Well is a complex interplay of factors, including ground pumping, climatic conditions, geological history, and the broader ecological context. As an expert in this field, I emphasize the urgent need for sustainable water management practices, conservation efforts, and a holistic approach to address the challenges posed by dwindling water resources in the region.
