Jacobs Well not flowing – emergency conservation called for
Emergency 30% reduction in water use called for
Jacob’s Well, the famous natural spring known to be the longest
underwater cave in Texas, stopped flowing for the second time in
recorded history on the evening of October 20th. ” The lack of
rainfall and the continued pumping of the aquifer to serve local water
supply has caused Jacob’s Well to cease flowing,” stated Jack Hollon
of the Wimberley Valley Watershed Association (WVWA) and the Hays
Trinity Groundwater Conservation District.
Jacob’s Well has been hovering at between one and two cubic feet per
second for the past several months. The well continued to flow through
the drought of record in the 1950′s and was the primary source of
water flowing to the Blanco River which is also at it’s lowest flow
since the drought of record in 1956. Jacob’s Well is the barometer for
the health of the aquifer; the well ceasing to flow at this time is a
major environmental event, as it stopped for the first time in
recorded history in the summer of 2000.
Jacob’s Well is the primary source of water flowing from the Trinity
Aquifer to form Cypress Creek, the beautiful stream that rambles
through the cities of Wood Creek and Wimberley. “Losing the flow to
Jacob’s Well is a signal that the aquifer is stressed and we all need
to conserve water immediately. The WVWA is calling for a moratorium on
permitting of any new wells or sub-divisions in the Trinity aquifer
recharge zone that sustains Jacob’s Well. We also request that all
water supply companies and individual well owners move into drought
contingency and cut back water use by 30% or more,” stated David
Baker, Executive Director of WVWA.
The Jacob’s Well Natural Area was recently awarded a grant from Hays
County parks and open space bond funds to purchase the 55 acres around
the well and to establish a research and environmental education
center. WVWA was founded in 1996 and acquired the property in 2005.
The WVWA’s mission advocates protecting the water quality and quantity
of the area by promoting sustainable watershed management through
community education, conservation and land protection.
“The economic well being of this region is directly linked to the
protection of our groundwater and surface water resources. We know
there is a direct correlation between the flow from Jacob’s Well and
the withdrawl of groundwater through pumping. This impacts not just
our area but all of the people and businesses located downstream from
Jacob’s Well. Therefore we must all work to conserve and protect this
invaluable resource for those of us who live, work and enjoy the
Wimberley Valley and this area of the Hill Country.” Stated Dr. Cox,
President of WVWA
The community’s investment in protecting Jacob’s Well, Blue Hole and
Cypress Creek is threatened by unchecked development and the lack of
authority to regulate pumping from the Trinity aquifer. Land in the
recharge zone of Jacob’s Well must be protected from any further
development. As a community, we need to stop over pumping groundwater
and advocate legislation to mandate rainwater harvesting for all new
development in this sensitive area to preserve Jacob’s Well and the
environmental and economic future of this valley.
