Seminar on Safety Evaluation of Existing Dams
Because the often-catastrophic consequences of dam failure are unacceptable, the need for trained personnel is essential. This seminar provides attendees with comprehensive instruction in dam safety examination and evaluation. Although references will be made to organizational procedures and units of Reclamation, the principles, concepts, and procedures are readily adaptable to any organization conducting a regulatory or in-house dam safety program for existing dams.
The basic seminar emphasizes the importance of dam safety and provides information and instruction in dam safety surveillance, including periodic review of pertinent records, visual examination, and monitoring of instrumentation. Hydrologic considerations, concrete repair, remedial measures for dams, and emergency action planning are also discussed. The seminar is suitable for engineers, technicians, maintenance personnel, and administrators responsible for dams.
The seminar includes a visit to local Colorado dams to practice inspection techniques.
In addition to the basic seminar, three concurrent workshops are being presented on Thursday afternoon to provide more information on the following subject areas:
- Engineering Geology and Dam Safety Workshop presents an introduction to geologic investigation and evaluation relative to dam safety static and seismic issues.
- Evaluation and Response to Seepage and Internal Erosion Concerns presents seepage process and failure modes, types of sinkhole formations, and approaches for investigating and responding to seepage and internal erosion conditions.
- Emergency Management presents key elements of a dam owner's responsibilities regarding facility operations, namely detection, decision making, and notification and how to exercise those responsibilities through simulated events.
The seminar instructors will consist of a group of professional engineers and geologists who have a great deal of experience and knowledge in the areas of design, construction, operation, maintenance, instrumentation, and dam safety evaluation. Many of the instructors have conducted training programs for Reclamation and other US and foreign personnel involved in dam safety.
Participants will be responsible for their own transportation to and from Denver International Airport. Shuttle services are available (Super Shuttle, www.supershuttledenver.com , 1-800-BLUE VAN (258-3826), or phone 303-370-1300), with a fare of about $30.00 each way for each passenger. The RTD Skyride, Route Schedule AF (http://www.rtd-denver.com/skyRide_SubHome.shtml for information on rates and schedules) is available to the Cold Springs Park-N-Ride (ends about 3 blocks from the Hampton and Homewood hotel complex), with a fare of $13 each way for each passenger. Reclamation will provide transportation to and from the dam sites during the field trip on Wednesday.
The seminar will be held at the Fish & Wildlife Service Building, 134 Union Boulevard, Lakewood, CO 80228. There are three hotels within walking distance, the Hampton Inn, located at 137 Union Blvd, (303) 969-9900, Homewood Suites by Hilton located at 139 Union Blvd, (303) 716-5737, and the Sheraton Denver West Hotel (720) 963-2030 located about 3 blocks from the seminar. A limited number of rooms at the government rate are blocked at each of these hotels. Room rates are $156 per night single (before taxes). To make hotel reservations, call the hotels directly before June 9, 2014 and refer to the Group "Bureau of Reclamation SEED SEMINAR" to receive the government rate. Rooms at the government rate will be released on June 9, so please try to reserve your room prior to this date.
Government rate lodging at each location includes complimentary full breakfast buffet. Additionally, an evening reception with light meal and beverages is also complimentary at the Homewood suites. The Sheraton includes club level access.

Registration and Seminar Fee
Reclamation's Dam Safety Office is providing the seminar at no cost to attendees. However, due to agency restrictions, the audience is limited to Federal agencies to the exclusion of States, local Governments and private interests. Please visit the Association of State Dam Safety Officials website for dam safety training alternatives.
DOI Employees are required to register and obtain supervisor approval in DOI Learn. To locate the course in the DOI Learn catalog, use the keywords: SEED Seminar. Be sure to choose the class on July 14, 2014. You will not be added to the roster until supervisory approval is received in DOI Learn. Registration is open to Federal agency, Reclamation water district partner and tribal employees. For non-DOI registration, please fill out the registration form and return it to SEEDSeminar@usbr.gov no later than June 9, 2014.
Registration is limited, and applications for attendance will receive consideration according to the order in which they are received. Participants will receive a seminar notebook (not available separately); Safety Evaluation of Existing Dams Manual; the book, "Dams and Public Safety," and some additional material to supplement the lectures. It is suggested that you leave space in your luggage for these books.
