The Cost of Rehabilitating Dams in the U.S. (2023)
In 2022, the ASDSO Board of Directors established a task force to review and update the methodology and processes that were developed several years earlier by ASDSO to estimate the costs to rehabilitate non-federal dams in the United States (U.S.). This was a one-year project financed by ASDSO. The updated methodology and processes used readily available data to estimate the number of dams in need of rehabilitation based on dam height, age, and Condition Assessment rating. Data from more than 500 dam rehabilitation projects nationwide, ranging from $10,000 to more than $500 million, was used in determining the total amount of funding needed for dam rehabilitation at a national level.
The purpose of this report is 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. The findings and methodologies are not meant to be used to estimate a specific dam rehabilitation cost.

Dam Owner Fact Sheet Booklet (2022)
ASDSO has developed a booklet of fact sheets that provides guidance on specific issues many dam owners face. More information, as well as individual fact sheets, can be found under the Resources for Dam Owners and Operators section.

Summary of State Laws and Regulations on Dam Safety (2020)
This publication is a summarization of the United States’ state laws and regulations pertaining to dam safety. Although laws and regulations vary from state to state, this document categorizes the main functions of each state’s policies and thus create a quick reference to specific issues.

ASDSO Podcast: A Dam Conversation With...
A Dam Conversation With... is the official podcast of the Association of State Dam Safety Officials. It features interviews with industry leaders and shares stories of career development, lessons learned, industry history, and more. A Dam Conversation With... launched in September 2024 and is available on all major podcasting platforms.

Dam Failure and Incident Investigation Guide (2021)
This guide shares lessons from previous dam incident and failure experiences and is designed to assist state dam safety agencies and dam owners in making good decisions during the chaotic and high-stress period during and following a dam failure or major incident. As with any guide, it is expected that some refinements may be identified as more investigations are completed. As such, this guide is being issued as a “living document”, with the expectation that applicable revisions or updates will be made as necessary. The initial version was published in December 2011. This current version 2.0, dated March 2021, features revisions from lessons learned during the past ten years.
