President’s Statement On behalf of the Board of Directors, I am honored to present the ASDSO Fiscal Year 2026 Annual Report. This report documents another year of progress, demonstrating the enduring impact of our community’s commitment to a future where all dams are safe. And of course, we must also recognize the exceptional efforts of our staff, committees, and members whose dedication is the engine of our success.

I invite you to explore the achievements and exciting plans that are detailed within this report — but first, let me touch on a few that stand out in my mind:

Career Development and Student Outreach Committee is developing and piloting an educational curriculum to inspire the next generation of dam safety professionals.

I am particularly pleased to share that our legislative advocacy efforts, both at national and state levels, are producing promising returns. Legislative advocacy takes time and concerted effort to build support, negotiate with stakeholders, and navigate the world of politics, where priorities can shift in the blink of an eye. This past year, we saw landmark legislation in Michigan and Alabama, as well as the introduction of the DAMS Act in Congress and the incorporation of many of its provisions in the pending WRDA bill.

While celebrating our successes, we also recognize that there are real headwinds to work against. The nationwide shortage of qualified dam safety engineers remains critical, affecting programs at every level. Our advocacy for robust state and federal funding and the next cycle of NDSP authorization is more vital than ever, but with political attitudes trending away from large new spending bills, we must approach this with tact and finesse. We will continue to support our federal agency partners, while demanding that agency leadership return that support. We must make the case clear: cutting-edge expertise, support from state legislatures and federal agencies, and robust funding are indispensable to ensure public safety and maintain public trust. Neglect leaves us less secure and less resilient.

We are excited to share some amazing material developed with our strategic partners, including Bigfoot himself, to promote low-head dam safety awareness. This will save lives! In recognition of the diversity of our state dam safety programs and their portfolios, our Technical Training Committee, along with volunteers from GEI Consultants and multiple state regulators, has been developing a framework for integrating risk-informed decision making tools and training into state programs while respecting that a one-sizefits-all solution does not exist. And lastly, our volunteers, the heart of this organization, continue to impress; the

To every member, volunteer, and partner: thank you. Your dedication is the core of our organization and our collective progress. I am incredibly proud of what we have achieved together and eager for the work ahead, including the execution and expansion of our national public awareness campaign and continued advocacy in Washington, D.C. With our collective dedication and mission-driven attitudes, the future is bright.

John Roche, P.E. President

2025-2026 Annual Report

To Our Members I’m proud to present this Annual Report for Fiscal Year 2026 (FY26), covering objectives carried out between July 2025 and June 2026. As you read this, we hope your biggest takeaway is that ASDSO continues to provide strong programs for its membership and that we are continually making progress toward our mission.

We come to the end of the year grateful to all our volunteers. You will see the long list here of members who sit on many committees, task groups, and interest groups. I want to acknowledge and thank the staff of ASDSO for their dedication and talents. From a financial standpoint, we were able to improve our financial position due to the success of the annual conference in Cleveland, training income, a growing membership, and the generosity of our sponsors and donors. Thank you to the National Dam Safety Program for sponsoring many projects. We are beginning to grow the donor program for the new public safety campaign around low-head dams, which we affectionately call Bigfoot Says. As we move into a new fiscal year, you all will begin to see the campaign come to life. We are very excited to show this to you in the coming months. Please take a moment to review our work together. Thank you for providing us with your membership dues, volunteer time, and overall support for the mission.

Federal & State Legislative Advocacy TOP OBJECTIVE MET

Introduction of the DAMS Act to reauthorize the High Hazard Potential Dam Rehabilitation Grant Program for an additional five years, make other technical improvements, and incorporate its provisions into the Water Resources Development Act of 2026 (WRDA). ASDSO worked closely with Representatives Jeff Van Drew (R-NJ02) and Dina Titus (D-NV01), as well as staff for the House Transportation and Infrastructure Committee and the Senate Environment and Public Works Committee to ensure the HHPD reauthorization and amending provisions were included in WRDA.

OTHER KEY HIGHLIGHTS AT THE FEDERAL LEVEL: • Cultivating communication with members of Congress. Over the course of the year ASDSO members and representatives met with more than 100 members of Congress and their staff to advocate for strong state dam safety programs, build bipartisan support for HHPD reauthorization, and advance other dam safety priorities such as increased appropriations to federal dam safety grant and loan programs. • Strengthening of coalition partnerships. Collaboration with other organizations continued to broaden the reach and support for dam safety nationwide. • Defending dam safety funding. ASDSO worked with congressional appropriators to secure a $11.4 million appropriation for the HHPD grant program in the FY26 Homeland Security Appropriations bill. This represents the first congressional investment in the program since the Infrastructure Investment & Jobs Act (IIJA). KEY HIGHLIGHTS AT THE STATE LEVEL: • Increased monitoring nationwide of proposed state bills affecting dam safety. • Support for dam safety in Alabama, Kansas, and Michigan: » ASDSO worked with the Alabama Legislature to enact legislation consolidating the state's dam safety program under the Alabama Emergency Management Agency. The new law provides a single administrative home for the program, strengthening coordination and positioning the state for more effective oversight of dam safety. » ASDSO has been a leader in the effort to reform Michigan's dam safety program in accordance with the recommendations of the Dam Safety Task Force and the peer review. This included participating in a broad stakeholder coalition, submitting written testimony in support of the legislation, and organizing ASDSO members to testify before House and Senate committees. » ASDSO supported successful legislation through written testimony in Kansas that strengthened the state's dam safety program by modernizing regulatory requirements and improving program administration, and opposed a burdensome proposal that would have complicated the regulatory process.

2023-2024 Annual Report 2025-2026

Support for National Advisory Councils & Boards As of the date of publication of this report, the FEMA National Dam Safety Review Board was still under the directive that formally terminated many of the federal advisory boards across all agencies. ASDSO worked with Congressional leaders during the fiscal year to insert language in the DHS FY26 appropriations bill requiring FEMA to report back to Congress on the status of the Board and to provide a timeline for appointing members to the Board. ASDSO members continue to serve on the DHS, Dams Sector Coordinating Councils.

Peer Review Program In 1990, ASDSO's Peer Review Program was piloted, and since then, it has completed state, federal agency, and private sector reviews. The program is reviewed by a diverse and independent group of experienced dam safety professionals and can help improve the management and execution of a dam safety program. The ASDSO program features a defined process that leads the state, agency, or company through an introspective "self" evaluation, assessing the mission, objectives, policies, and procedures relative to the organization's governing regulations and generally accepted standards of practice for Dam Safety Engineering and Management. In Fiscal Year 2026, the following reviews were completed: • Tennessee Valley Authority • Alaska Department of Natural Resources • Portland Water Bureau Five reviews were launched during FY26, with completion dates planned for FY27.

Media Outreach - Year in Review 25+ UNIQUE ARTICLES, 20+ MEDIA REQUESTS FOR INFORMATION ASDSO recognizes the importance of media engagement in increasing the public's awareness of dams. Ongoing engagement with the media leads to more proactive communication and more accurate and effective reporting. ASDSO was directly represented in almost 30 unique news articles from July 2025 to June 2026. Many other articles were later syndicated to additional outlets, helping ASDSO reach an even wider audience. Many more ASDSO subject matter experts represented their own organizations in articles while coordinating with ASDSO on talking points.

Notable Media Outlets: Mother Jones, Washington Post, Bridge Michigan, Honolulu Civil Beat, Live Science & Inside Climate News Top Topics: State Programs Legislative Advocacy, Dam Rehabilitation, Aging Infrastructure & Funding Concerns

Thank you to all the subject matter experts who made this possible!

Volunteers SPOTLIGHT ON NEW VOLUNTEER EFFORTS Introducing ASDSO Ambassadors The Board of Directors approved a new ambassador standing committee in June of 2025, and the Ambassadors Program was fully launched during the annual conference in Cleveland, Ohio. At the conference, ASDSO ambassadors supported attendees at registration, in the exhibit hall, and during the opening sessions and annual awards luncheon, and hosted a first-time attendee breakfast. At ASDSO, we pride ourselves on being leaders in the dam and levee safety community. As such, our ambassadors are held to a high standard while representing the association. ASDSO values the time and effort each ambassador provides to the association and recognizes their time and effort in the voluntary role. The committee will continue to expand its support for members during FY27.

Want to become an ambassador? Visit our Volunteer Opportunities page on Collaborate to apply.

Volunteers Assisting with State Dam Safety Program Performance Report Updates ASDSO routinely publishes State Dam Safety Program Performance Reports for each of the 50 states. The reports include data on condition ratings, state staffing, state budgeting, EAP completion, a comparison to the national benchmark, and more. The reports are useful for educating the public, media, and other stakeholders about specific state regulatory programs and the dams they regulate. Over the past year, an ASDSO task force has been re-envisioning the report templates and developing clearer ways to present data to people outside the dam safety industry. Changes so far have included updated text, reworked charts, and changes to the data included and excluded in the report. The group has also considered additional reports targeted at specific audiences and a national performance report with compiled state performance data. The final State Dam Safety Program Performance Reports are expected to be completed by Fall 2026. Reports will be available at DamSafety.org/States.

A special thank you to all the volunteers who made these projects a success!

Bigfoot Says Avoid Low-Head Dams

ASDSO LAUNCHES PUBLIC SAFETY AROUND LOW-HEAD DAMS AWARENESS CAMPAIGN We in the dam safety profession collectively know how heartbreaking it is to learn of tragedies caused by recreating around dams or dam failures. Now, for the first time in ASDSO’s history and thanks to seed funding from the FEMA National Dam Safety Program, we are launching a multi-year national awareness campaign. ASDSO announced the campaign’s concept at the Dam Safety 2025 National Conference and introduced our ‘celebrity’ spokesperson, Bigfoot. The campaign website, BigfootSays.org, was also launched at the conference. ASDSO worked closely with Doe Anderson, a nationally recognized advertising firm, to re-imagine the character and develop a long-term strategy. Like Smokey the Bear before him, our friendly Bigfoot is poised to become a beloved spokesperson for all ages, activity levels, and walks of life. Following the conference, the Board of Directors voted to continue the effort and provide additional funding for production of the first round of video, print, and audio

materials. ASDSO subject matter experts and staff have worked closely with Doe Anderson over a six-month period to bring the campaign from concept to reality. The team developed scripts for 30-, 15-, and 6-second PSAstyle videos, scripts for audio messaging, and concepts for print and social media. Production of these assets took place in early FY27, with the next phase kicking off at the Dam Safety 2026 conference.

This campaign could not be possible without the support of our campaign donors and volunteers. Your support was vital in kickstarting this ambitious campaign! To learn more about or donate, visit BigfootSays.org Members can also donate through the Portal by visiting Damsafety.org/SupportBigfoot

Career Development & Student Outreach 2025-2026 MEMORIAL UNDERGRADUATE SCHOLARSHIP ASDSO's Dam Safety Scholarship Program was established in 1992, recognizing that one of the keys to achieving the Association's goals is the development of well-trained technical persons. Through the program, ASDSO annually awards a scholarship to at least one undergraduate senior who has demonstrated an interest in pursuing a career related to dam design, construction, and operation and is studying in a related field.

Madi Pollei Brigham Young University

Madi was awarded a $10,000 scholarship and a travel stipend to attend the Dam Safety 2025 conference in Cleveland, Ohio.

STUDENT PAPER COMPETITION The yearly Student Paper Competition is open to undergraduate and graduate students pursuing degrees at U.S. universities or colleges.

DAM MODEL COMPETITION The Dam Model Competition calls for K-12 classes, student branches of professional organizations, or other students interested in dam safety safety to construct a tabletop-size dam model. Groups must also develop a plan to use the model to educate the public on dam safety. The Dam Model Competition is funded by the Bruce Tschantz Memorial Fund.

K-12 LESSON PLAN SUBCOMMITTEE A subcommittee of the Career Development and Student Outreach Committee, the K-12 Lesson Plan Subcommittee believes that the earlier one can become exposed to dams, the more likely they are to become interested in the topic and potentially pursue a career in the industry. There is a documented shortage of college students and early career professionals that elect to pursue a career in infrastructure, and more specifically dams. The intent of the K-12 Lesson Plan project is to perform research and set the boundaries for developing lesson plan(s) targeted at K-12 students that introduce them to dams and high-level concepts on how they work. In FY26, the subcommittee completed Phase 1 of their workplan, which involved initial discovery and research. A curriculum was developed, which will be tested in the coming year through a pilot program.

Extreme rainfall events happen almost every day somewhere—maybe not in your backyard or above a dam in your community, but around the country and the world. Sometimes we see them in the news on TV, and sometimes these extreme rainfall events get names like Katrina, Irene, Helene, and Sandy or are referenced by location, like Boulder, Colorado (2013), or Pensacola, Florida (2014), or Central, Texas (2025). Climate experts put all the historical extreme rainfall events into a database to determine how often they happen, how big they can get, and what the threat is for individual communities. Experts consider hundreds of years of data at thousands of locations and have a broad understanding of the climate and the potential for extreme rainfall events. They know that extreme rainfall happens, may exceed the years of available data, and may be happening more often. Dam engineers use this climate database to predict the extreme rainfall events they use in dam design. Mother Nature very often surprises us with the unexpected ferocity of her storms. Climate data helps engineers anticipate these surprises by allowing them to estimate the magnitude and frequency of extreme storm events. This publication will help explain and justify the engineering principles involved with predicting extreme rainfall events and how they are used to design safe, functional, and economical dams. It will connect the concepts of rain, dams, failure, and flooding impacts downstream.

Living Near Dams: Know Your Risks Dams provide drinking water, hydroelectric or water power, flood control, recreation and many other benefits to people or local economies. However, dams can pose significant risks to people living downstream should they fail. There are dams in every U.S. state. It is important to know if you and your loved ones live, work or recreate in areas that may be affected by the presence of a dam and what to do if this is the case. This booklet was created to help answer questions about dams: what purposes they serve, what risks are associated with dams and where you can get information about how to react if you are affected by a dam.

DAM OWNER ACADEMY: FREE SELF-PACED DAM OWNER EDUCATION – DamOwner.org ASDSO launched two free, self-paced training options for dam owners, operators, and others interested in learning the basics of dam ownership and operation during FY26.

Course Two is more advanced and is recommended for those responsible for day-to-day oversight of dam operations and maintenance.

The courses are part of ASDSO's new Dam Owner Academy and are designed for non-engineers. Since the courses are self-paced, participants can complete them at their convenience over time. Currently, two courses are available through the Dam Owner Academy, with more to come.

There are no Professional Development Hours for these products.

Course One is an introduction to specific issues that many dam owners face. It focuses on the ASDSO Dam Owner Academy video series and related fact sheets.

DAM FAILURES AND LESSONS LEARNED WEBSITE – DamFailures.org The Lessons Learned from Dam Failures and Incidents website is one of ASDSO's most popular resources. With the addition of 11 new studies in FY26, the website now has more than 70 case studies and 40 lessons learned from dam failures to explore.

New Studies Added in FY26 Case Studies: Carsington Dam (United Kingdom, 1984), Abu Mansour & Al-Bilad Dams (Libya, 2023), Kingsley Dam (Nebraska, 1972), Feijão Dam B-1 (Brazil, 2019), Harmony Gold Mine No. 4 Tailings Dam (South Africa, 1994), Panguitch Lake Dam (Utah, 2024), Bonasa Breaks Ranch Dam (Washington, 2017), and Wanapum Dam (Washington, 2014) Lessons Learned: Past successful dam performance does not guarantee future successful performance; The Study of Past Dam Failures and Incidents is Essential for Keeping Today’s Dams Safe. Thank you to the volunteers from the Dam Failures and Incidents Committee who conduct research and compile content for the website. Additional thanks to the FEMA National Dam Safety Program for yearly funding support for research.

Exploring the Dam Failures Website DamFailures.org provides educational information relating to dam failures and incidents in an innovative, user-friendly manner to assist owners and practitioners with critical design and operational decisions. The website presents links to individual case studies and 'lessons learned' pages that summarize historical dam incidents and failures and the valuable information gleaned from them. Each page contains background and description, photographs, videos, best practices, and other resources related to the case study or lessons learned being addressed. The contents of this website encompass a range of failure modes, dam types, and dam safety topics, including best practices regarding engineering and design practices, human factors, emergency planning and response, operation and maintenance, and regulatory issues.

THE NATIONALLY RECOGNIZED REPORT ON THE COST TO REHABILITATE THE NATION'S NON-FEDERAL DAMS In 2025, ASDSO updated The Cost of Rehabilitating Dams in the U.S. report. In this update, ASDSO estimated that the total cost to rehabilitate the nation's non-federal dams is $165.2 billion. The cost to rehabilitate just the most critical dams was estimated at $37.4 billion, a cost that continues to rise as maintenance, repair, and rehabilitation are delayed. ASDSO developed this report to inform national and state policy decisions and provide the public and the media with a high-level understanding of the national dam rehabilitation need in terms of estimated costs.
