GENERAL MANAGER’S MESSAGE

By: Roland Ruiz General Manager

WE’VE COME A LONG WAY...

ON THE COVER OF THIS MAGAZINE, WE ARE PLEASED TO INTRODUCE A NEW EAA LOGO.

The logo is an artistic metaphor for our work that gives us a new creative platform to rebrand our identity. This logo is intended as a conceptual-but-iconic identifier of who we are and what we aspire to be as an agency. Strategically, the design’s somewhat abstract nature lends itself to interpretation at a time when we are reimagining our future within the next generation of our mission. The looping interconnection between the three letters E-A-A appeals to the idea of unlimited opportunities by capturing within it an infinity insignia, the mathematical symbol of boundlessness. Here, infinity is represented paradoxically to illustrate that those things that are boundless – concepts such as inclusion, imagination, and innovation -- are made possible through

the creativity and collaboration to which we have bound ourselves. It also reflects the connective nature of the Edwards Aquifer system, which links us together across a vast region, and offers the opportunity to unite rather than divide through a single, interwoven mission focused on maximizing the long-term sustainability of the Edwards Aquifer for everyone. We’ve come a long way over the past 30 years, but we still have a long way to go. The new EAA logo conveys a more open-ended, imaginative way of thinking and considering the infinite possibilities of managing, enhancing, and protecting the Edwards Aquifer well into the future.

managing the aquifer to the benefit of all who rely on it. The period of record for these sites as well as their respective locations are primary factors in both their selection as index locations and their usefulness as key modeling points in the EAA groundwater model. The EAA groundwa ter model is designed to mimic system behavior and function as a tool for developing manage ment methods designed to ensure continuous springflows in a repeat of the drought of record. Management methods, such as CPM, ensure compliance with the terms of the Edwards Aqui fer Habitat Conservation Plan (EAHCP) and the Incidental Take Permit (ITP) associated with it, by bringing added certainty to the region regard ing the Edwards Aquifer.

measurements to ensure data accuracy. One added difficulty in measuring springflow is the influence of surface runoff during rain events. USGS staff have a well-established process for separating the runoff from the springflow such that estimates are as accurate as possible, even after rainfall events. The Index Wells and two spring groups discussed herein are statutorily designated as measurement points for determining CPM. Importantly, each of these locations have significant data histories. For example, the continuous data record for J-27 goes back to 1940, for J-17 that record goes back to 1932, and for springflow the earliest record goes back to 1927 for the Comal Springs. These long periods of record are essential to

The two spring groups, Comal and San Mar cos Springs, are measured in similar fashion to the index wells, using a pressure transducer and telemetry equipment. Springflow at each system is estimated using methodology that involves calculating flow across a known chan nel cross section, in the streams just down stream of the springs. The height of water, combined with a known area of stream cross section provides a basis for making accurate spring discharge estimates. Much like the index wells, data are transmitted at 15-minute intervals to the USGS data servers, in units of cubic feet per second (cfs). USGS staff make calibration and reference measurements at the springs in similar fashion to the way that EAA staff conduct calibration and reference

equipment to minimize the risk of data loss in these wells. Data integrity is maintained by regular calibration checks at the Index Wells to always ensure the accuracy of the equipment. If water levels meet criteria for a change in EAA Critical Period Management (CPM) Plan stages, staff visit the well in question (i.e. J-17 Index Well or J-27 Index Well) to make confirmatory measurements prior to issuance of notice to make a change in CPM stage. The CPM is a groundwater reduction initiative implemented during periods of drought, when water levels and springflows are low.

The table in figure 1, showcases these data for both the San Antonio and Uvalde Pools. The San Antonio Pool is comprised of readings from the J-17 Index Well, Comal Springs, and San Marcos Springs. The Uvalde Pool is comprised of water level data from only the J-27 Index Well. Water level data are collected from the Index Wells in 15-minute intervals using a pres sure transducer paired with a telemetry device. Water level data are then automatically trans mitted to the EAA in near real time and reported in units of feet above mean sea level (ft msl). For added data security, each index well is equipped with redundant measurement

Our agency collects water levels from the J-17 Index Well, and J-27 Index Well, while the United States Geological Sur vey (USGS) measures flow rates from Comal Springs, and San Marcos Springs. Collectively, these data are considered the aquifer condi tions, which are displayed on the front page of our website in a table that is updated daily.

EAA CRITICAL PERIOD MANAGEMENT PLAN

HOW THE EAA MANAGES CRITICAL STAGE REDUCTIONS

CALL FOR CONSERVATION MEASURES

By: EAA Water Resources Department

CRITICAL AQUIFER LEVELS

THE SAN ANTONIO POOL San Antonio Pool pumping permit reductions apply to Atascosa, Bexar, Caldwell, Comal, Guadalupe, Hays, and Medina counties.

THE UVALDE POOL The Uvalde pool pumping permit reductions only apply to Uvalde County.

The intent of the EAA Critical Period Management (CPM) Plan is to sustain aquifer and springflow levels during times of drought. CPM applies to most well owners who have a permit to withdraw water from the Edwards Aquifer by temporarily reducing their authorized withdrawal amount.

Why do we need to know Springflow? The Comal and San Marcos Springs provide habitats for threatened and endangered species that are protected under the Edwards Aquifer Habitat Conservation Plan (EAHCP), which can serve as indicators species for the health of the aquifer.

CPM reductions differ for each aquifer “pool” and are based on 10-day averages of certain aquifer level and springflow readings which are indicators of the current condition of the aquifer.

Please note: Residents and businesses who receive their water from a public water system are encouraged to check with their water provider to determine to how stage reductions could impact them.

The EAA uses springflow to balance the water needs for more than 2.5 million people that rely on the aquifer.

For more information or questions, please call the EAA Critical Period Team at (866) 931-3239 or email us at info@edwardsaquifer.org.

Figure 2. EAA Critical Period Management (CPM) Plan for the Uvalde Pool.

Figure 1. EAA Critical Period Management (CPM) Plan for the San Antonio Pool.

*Stage 5 Comal Springs Flow - to enter this stage based on the springflow, the reading must be less than 45 cfs on a ten-day rolling average, or less than 40 cfs based on a 3-day rolling average. To leave this stage, the 10-day rolling average must be 45 cfs or greater.

CPM is triggered and declared for the San Anto nio Pool (all counties within EAA jurisdiction except Uvalde) when the 10-day average level at the J-17 Index Well, in Bexar County, drops below 660 feet above mean sea level (msl) or the 10-day average springflow at Comal or San Marcos Springs falls below 225 cubic feet per second (cfs) or 96 cfs, respectively. As a result, permit holders must reduce groundwater with drawals by 20% of their authorized annual with drawal amounts based on the number of days CPM is in effect.

in 10-day averages. These stages are illus trated in figure 1 and figure 2 and show the different degrees of critical period manage ment we implement based on a combination of conditions. For the San Antonio Pool, the area indexes are the J-17 Index Well, Comal Springs, and San Marcos Springs. However, for the Uvalde Pool the area index is only the J-27 index well. Therefore, required reductions increase as aqui fer levels or springflows decrease, depending on which pool is in CPM. For example, Stage 1 of

In addition, all municipal, industrial and irriga tion well owners are required to submit monthly withdrawal reports to the EAA for tracking of their pumping. These reports are reconciled at the end of the year to ensure permit holder compliance with the CPM reductions. What are the stages of permit reductions and when are they declared? The CPM Plan is divided into five stages of escalating, reduced-pumping requirements, each triggered by declining aquifer levels or springflow discharge rates as calculated

Who does this apply to? CPM stage reductions apply to all Edwards Aquifer well owners and groundwater permit holders authorized to pump more than three acre-feet annually. This applies to industrial, irrigation, and municipal users, including water utilities authorized to pump Edwards groundwa ter for delivery to their respective customers.

The EAA Critical Period Management (CPM) Plan helps sustain aquifer and springflow levels during times of drought by temporarily reducing the authorized withdrawal amounts of Edwards groundwater permit holders. By curbing pump ing from the aquifer during periods of little or no rain, this program is designed to slow the rate of decline in aquifer levels and spring dis charges until such time that it does rain, and the aquifer can recharge itself.

COTTON FARMING

By: Isabel Martinez EAA Senior Permit & Conservation Coordinator

AGRICULTURE OUT WEST

Every wonder how cotton is grown? Take a trip with us out to Hondo, Texas to meet with Anthony, a fifth generation farmer, to learn how this staple crop is grown and harvested. Watch the video here.

Cotton has long been the fabric of civili zation and has been a valuable crop for many millennia. It was critical in the devel opment of cloth and textiles in all parts of the world. Fabric made from cotton that dated to 3000 BC was found in Mexico. Across the world, cotton fragments were discovered in Asia that dated back to around 5000 BC. Its durability as a crop helped it become popular all over the world due to its hardiness and its ability to thrive in multiple climates and these same traits make it popular for producers to plant in the EAA region. Producers in Medina and Uvalde coun ties plant hundreds of acres of cotton, which helps the State of Texas be the largest producer

Cottonseed oil is used to make cooking oils, salad dressings, and shortening. The meal and hull from the seeds are used to make several things. They can be used to make fertilizer or to make feed for poultry, livestock or fish. There is short fuzz on the outside of the cottonseed that is called linters. Linters are used to make plastics, paper products and batting for mattresses and cushions. The stalks and leaves of the cotton plant are useful for their organic properties. Cotton stalks and leaves are often plowed under the soil to decompose and leave nutrients in the soil. Cotton that is raised in our region is produced for the lint and the seeds. The lint is processed at a gin and shipped throughout

the U.S. and other parts of the world while the seeds are processed for oil or livestock feed.

of cotton in the U.S. with an estimated 5 million acres of cotton planted annually. As a crop, cot ton does not require a lot of water to grow, has a natural resistance to disease and pests therefore requiring less pesticide. The entire cotton plant is useful. The most popular and well-known part of the cotton plant is the white fiber, or lint, that appears at the end of the growth cycle. The lint is what is used to make cotton cloth. Within the lint, seeds can be found. Cottonseed can be crushed and sepa rated into different products such as oil, meal, and hulls.

Cotton’s popularity is guaranteed to last well into the future. It plays a vital role in the economies of the communities where cotton is grown as well as providing the raw materials for manufactured products such as clothing, cooking essentials, and other industrial uses. Cotton’s ability to toler ate South Central Texas’s climate and low water requirements has made it and continues to make it a successful crop in the EAA region.

Renewing the Edwards Aquifer HABITAT CONSERVATION PLAN

Comal Springs riffle beetle

The Edwards Aquifer Habitat Conservation Plan (EAHCP) is a comprehensive plan designed to protect and conserve the threatened and endangered species that depend on the Edwards Aquifer and its associated ecosystems, particularly Comal and San Marcos spring systems.

Fountain darter

Texas wild-rice

The Incidental Take Permit is part of the EAHCP and was initially established in 2013 to safe guard species listed under the Endangered Spe cies Act (ESA) that depend on the aquifer and its associated ecosystems. The permit’s renewal is a pivotal step in ensuring the ongoing balance between activities like regional groundwater use and species conservation. The current ITP, which is set to expire in 2028, covers a 15-year period and has allowed for sus tainable management of the aquifer and spring systems while implementing measures to pro tect species such as the fountain darter, Texas

wild-rice, and the Comal Springs riffle beetle. As the renewal process progresses, the EAHCP, in collaboration with the U.S. Fish and Wildlife Service (USFWS) and other stakeholders, aim to extend the permit for another term, incorporating new scientific data, climate change projections, and lessons learned over the past decade. The permit renewal process, which began in 2022, is a four-phase process: 1) Listen and Learn, 2) Analyze, 3) Sign-Off, and 4) Document. Public involvement and stakeholder engage ment play a critical role in this process. “Trans parency is paramount in our efforts. We want

all stakeholders aware of what we are planning and we want their involvement in the process,” explained Scott Storment, EAHCP Program Manager. The EAHCP has been actively seek ing input from various stakeholders, includ ing municipalities, industries, environmental groups, and the general public, to ensure that the renewed permit, and accompanying Habitat Conservation Plan (HCP), reflects a broad range of interests and concerns. Public meetings and provide opportunities for community members to voice their opinions and contribute to the deci sion-making process.

One of the primary goals of the renewal process is to develop conservation measures that support the implementation of biological objectives, aligning with the EAHCP’s overall biological goals. This approach forms part of the three-part conservation strategy used in HCPs. Currently, the EAHCP Conservation Measures Subcommittee is conducting a compre hensive review of the current conservation measures, assessing their effectiveness, and identifying areas for improvement. This includes revisiting key strate gies such as springflow protection measures, habitat protection measures, and measures that contribute to recovery. More importantly, “we are evaluating the lessons learned from 11.5 years of implementation

with the best available science to enhance the EAHCP Program and ensure the long-term sur vival of our threatened and endangered species,” explained Kristina Tolman, HCP Senior Coordinator The renewal of the ITP will also require the EAHCP to prepare an updated plan, which will outline the specific actions and commitments necessary to min imize and mitigate the impacts on the Covered Spe cies. This updated plan will be subject to rigorous review and approval by the USFWS, ensuring that it meets federal standards for species protection under the ESA.

As the EAHCP moves forward with the ITP renewal, the process underscores the importance of continued collaboration among stakeholders to safeguard the ecological health of the Edwards Aquifer system and the region’s most sensitive species.

By fostering a deeper understanding of the aquifer’s role in our lives, these efforts promote conserva tion and stewardship. The Edwards Aquifer stands as a testament to the wonders of science, from its complex geology to the innovative techniques used in its study and management. By exploring the science behind this natural treasure, we gain a deeper appreciation for the delicate balance that sustains it and the criti cal need to protect it. As we continue to advance our scientific knowledge and technological capabil ities, we can better ensure the preservation of the Edwards Aquifer and the invaluable resources it provides for generations to come. A field trip to the EOC is more than just a day out of the classroom; it is an eye-opening adventure that inspires the next generation of environmental stewards. A visit to the EOC can turn ordinary days into extraordinary adventures and make learning an engaging and enjoyable process. These outings are not just a break from routine; they’re an integral part of a well-rounded education that fuels curios ity and passion for discovery.

like an Edwards Aquifer cave. The Edwards Aqui fer is formed in Edwards Limestone, a porous and permeable rock that allows water to flow through it. The aquifer is replenished through a process called recharge, where rainwater seeps into the ground and through the limestone, eventually reaching the water table. This natural wonder is essential for supplying drinking water, sustaining agriculture, and maintain ing the region’s delicate ecosystems. A permeabil ity exhibit inside the EOC demonstrates how water moves through a sand aquifer vs. a limestone aquifer. The Edwards Aquifer is also home to a diverse array of species found nowhere else on Earth. The ecosystem supported by the aquifer includes sev eral endangered species, such as the Texas blind salamander and the Fountain darter. Both can be found in the EOC aquarium. These species have adapted to the unique conditions of the aquifer, including its steady temperature and stable envi ronment. Scientific research on these species not only helps in their conservation but also provides valuable information about the health of the aqui fer itself. Water quality experiments in the Karst Theater help students test the pH of water samples. Sites such as the EOC play a pivotal role in rais ing public awareness about the importance of the Edwards Aquifer. Educational programs, commu nity outreach, and citizen science initiatives help

Fall is an exciting time for students of all ages. With the start of the new school year come the field trips! During visits to the EOC students can dive into the fascinating world of the Edwards Aquifer. The journey begins with a sense of anticipation and wonder, as students eagerly anticipate exploring the mysteries of this vital natural resource. The Edwards Aquifer, a subterranean marvel located in Central Texas, is a crucial natural resource with an intricate story that highlights the remarkable intersection of natural science and environmental stewardship. As the primary source of water for over two-and-one-half million residents and a vital com ponent of the region’s ecosystem, the Edwards Aqui fer exemplifies how scientific understanding and technological advancements can help us appreciate and protect our natural world. The science behind the Edwards Aquifer begins with its geology. The limestone rock that comprises the aquifer is rich in fractures and tiny to cave sized pores which act as conduits for water move ment. The Edwards Aquifer is located primarily underground, and difficult to visit it in person. At the EOC visitors can submerse themselves in sci ence by walking into a Cave Theater made to look

The Edwards Aquifer Authority (EAA) is unveiling a transformative rebrand that underscores innovation, inclusion, and imagination as integral to its mission of managing, enhancing, and protecting the aqui fer. This refreshed approach is highlighted through a series of community-focused events, starting with the EAA Rooted in Texas: Free Texas Native Plants Pick-Up event which occurred on Saturday, Octo ber 5th. Sponsored by H-E-B, this free eco-friendly drive-thru event provided attendees with native plants, encouraging sustainable gardening practices and supporting aquifer protection. In addition to the plant pick-up event, the EAA is engaged in other key initiatives, including the 2024 Dos Rios Watershed Cleanup with the City of New Braunfels and a lecture by naturalist and popular YouTuber, Joey Santore, at the San Anto nio Botanical Garden, both designed to foster ecological awareness and responsibility. The EAA is also sponsoring and partnering in the biennial Confluence of Young Conservation Leaders, where Helen Holdsworth, Chief of Engagement at the Witte Museum and Co-Chair of the conference,

highlighted the importance of this collaboration: “The EAA’s commitment to supporting young con servationists through this partnership is vital for shaping the future of environmental stewardship. Empowering these future leaders is essential for driving innovative solutions and fostering a strong, engaged community.” A key event in communicating our commitment to forward-thinking solutions is the annual EAA Sum mit, where EAA’s executive leadership provides crucial updates on our water resources and “Next Generation” initiatives. This event fosters collabora tion with elected officials and civic leaders, enhanc ing community engagement and shaping the future of aquifer protection. With eyes toward coming decades, the EAA is tak ing on a new look to reflect its focus on preparing for the future. “Our rebrand symbolizes infinite possibilities for how we protect and engage with the aquifer,” said Eduardo Flores, Creative Manager at the EAA. “The new logo incorporates the infinity symbol, reflecting the endless cycle of water and

our continuous conservation efforts. By merging science with creativity, we’re demonstrating how our mission is evolving to tackle future challenges.” He added that this spirit of innovation and engagement extends to the EAA’s community outreach efforts, like the upcoming events we have planned, which are all designed to foster a deeper connection with the public in support of aquifer protection. These fall events mark just the beginning of a broader initiative. Looking ahead, the EAA plans new activities, including community contests and programs designed to engage residents of all ages and interests across the region. The “Rooted in Texas” event, the EAA Summit, and partnerships like the Confluence of Young Conservationist Lead ership showcase our commitment to inclusion and underscore that safeguarding our water supply is a collective, community-driven effort. The EAA is ded icated to creating a sustainable future that inspires and involves every generation in the ongoing stew ardship of the Edwards Aquifer.
