The Challenges of Dams in Cold Climates
Design, Construction, Permitting and Environmental Issues
Alaska, Canada and High Elevation Dams
This USSD Workshop will be held in collaboration with the National Hydropower Association, following the NHA-Alaska Regional Meeting. Participants are encourage to attend both events (Registration is separate).
September 19: NHA Alaska Regional Meeting
September 19: NHA/USSD Welcome Reception 5:30 pm
September 20-21: USSD Workshop on the Challenges of Dams in Cold Climates
September 22: Optional field trip to Lower Eklutna Dam Removal Site
Why You Should Attend
- Engineering, construction and environmental issues in cold climate and high altitude regions are topics that are not often presented in dam industry workshops and conferences. Take advantage of this rare opportunity to discuss these important topics with industry experts.
- A training session on the International Hydropower Sustainability Assessment Protocol will be presented for the first time in the U.S.
- Case histories will be presented by top experts from around the world, reviewing some of the most high-profile projects in North America, including Site C Dam (British Columbia), Muskrat Falls Dam (Labrador), Susitna-Watana Dam (Alaska), Keeyask Dam (Manitoba) and many more small and large dams in the US, Canada, and Alaska.
- It's cost effective! During the "shoulder season" in Alaska, airfares and car rental rates are very reasonable. And the rate at the Hotel Alyeska is a fantastic $109/night, including required fees.
The Workshop will bring together design and construction experts from the U.S. and Canada and is aimed at both seasoned professionals and those in the earlier stages of their careers. The two-day workshop will include presentations by experts as well as breakout groups and discussion. Following the Wednesday morning Plenary Session, breakouts will feature two tracks:
Track B will include a one-day special training session. On Thursday, Dr. Joerg Hartmann will lead a training session on the International Hydropower Sustainability Assessment Protocol. This is the first time this topic has been presented in the U.S. Dr. Hartmann was part of the Hydropower Sustainability Assessment Forum, which developed the Protocol, and he is now an accredited lead assessor and has applied the Protocol on more than 20 hydropower projects worldwide. This leading-edge training session is not to be missed.The Workshop is championed by Robert Cannon of Schnabel Engineering, with the assistance of Denise Bunte-Bisnett of Santee Cooper.

- Sweetheart Dam, SE Alaska
- Terror Lake Hydro Project Hidden Diversion Project, Kodiak Island, Alaska
- And many more
An optional field tour will take place on Friday, September 22, to a dam removal project just north of Anchorage. The project involves the demolition of the 61-foot high concrete Lower Eklutna Dam. The tour also includes a visit to a smaller dam on the glacial Upper Eklutna Lake in a scenic glacier-carved valley. The lower reservoir is filled with sediment, and the dam is obsolete. is intended to reestablish a salmon run in the Eklutna River. At the time of the field trip, the dam should be nearly demolished, and will be in the process of being wrapped before the winter freeze.
For those who want to walk down to the dam site, it is a strenuous climb down and back up a 400-foot flights of aluminum stairs, as shown in the aerial photo.
The field trip will leave the Hotel Alyeska at 8:00 a.m. and will return to the hotel by 4:00 p.m. Arrangements will be made for those with rental cars to leave their cars in Anchorage during the tour, and/or to take participants at the Anchorage airport by 3:00 p.m.
Note: USSD reserves the right to cancel the field trip for any reason, including inadequate attendance, weather, or site conditions that might affect the ability to tour the site. If the site tour is not possible, USSD will give as much advance notice as possible, and may be able to arrange a visit to cultural sites in the area in lieu of the site tour.
