Geo-referenced water dam database, organized by region worldwide. An Excel file contains the database and legend. Notes, References, and a document on the importance of dams is also available.
This brochure provides a summary of the information presented in FEMA P-484, Technical Manual: Conduits through Embankment Dams, including the effects of conduits on embankment dams, internal erosion and backward piping erosion, the factors that can lead to embankment dam failure, and best practices for conduits through embankment dams.
This brochure is designed to help the dam owner manage and reduce nuisance wildlife and wildlife damages at earthen dams. The brochure provides information on the types of nuisance wildlife damages, wildlife observation during routine inspections, wildlife identifcation, and basic damage repair.
The dam owner is the frst line of defense in the appropriate maintenance and safe operation of dams. This brochure describes the dangers presented by problem vegetation on earthen embankment dams and discusses how to identify problem vegetation. A quick quiz is included for dam owners to determine whether their dam may be at risk for problems related to inappropriate vegetation.
For structures under the jurisdiction of the USBR, the design standards present clear and concise technical requirements and processes to enable design professionals to prepare design documents and reports necessary to manage, develop, and protect water and related resources in an environmentally and economically sound manner in the interest of the American public.
This document provides procedures and guidance for best practices concerning embankment dam flter design and construction and represents an effort to collect and disseminate current information and experience having a technical consensus. This document is intended for use by personnel familiar with embankment dams, such as designers, inspectors, construction oversight personnel, and dam safety engineers.
While not specific to tailings, this webinar includes valuable knowledge for tailings engineers. The objectives of this on-demand seminar will be to identify the current status of existing dams and levees in the United States, to learn the basic fundamentals of performing a dam/levee safety inspection, to learn how to perform a dam safety analysis and assess risks to levee freeboard, and to identify various rehabilitation practices. Topics to be covered in this on-demand seminar will include a history of dams and levees, an overview of dam safety and levee criteria in the United States, identifying the consequences of failure, determining the safety of existing dams and levees, and developing techniques for rehabilitating aging dam and levee structures.
BC Chief Inspector of Mines - The Mount Polley tailings dam, owned by Imperial Metals, breached 4 August 2014, releasing its free pond water and a portion of the tailings into Polley Lake. The spill flooded Polley Lake, creating a plug at Hazeltine Creek, and continued into nearby Quesnel Lake and Cariboo River. The cause of the dam breach and subsequent tailings spill has been investigated with a final report published 31 January 2015, the Independent Expert Engineering Investigation and Review Panel assessment of the Mount Polley Tailings Storage Facility Breach.

Safe dam operation includes comprehensive, state-of-practice guidance on timely inspection and observation of wildlife damages, accurate wildlife identification and mitigation, and appropriate dam design, repair, and preventive measures. This technical manual provides guidance to dam specialists, including dam owners, operators, inspectors, state dam officials, and consulting engineers, in the following areas: (1) the impacts wildlife can have on earthen dams; (2) habitat, range, description, and behavior of common nuisance wildlife to aid in the proper identification at the dam; (3) state-of-practice methods to prevent and mitigate adverse wildlife impacts on earthen dams; and (4) state-of-practice design guidance for repair and preventive design associated with nuisance wildlife intrusion.
