Suzanne Pritchard reports reports how a recent drowning at a US dam has highlighted why both dam owners and the general public must put safety at the forefront of their minds. Experts agree that low head dams can lull river users into a false sense of security. They do not appear to be dangerous due to their smaller size, which is particularly true if viewed from a boat or canoe upstream. Creating greater awareness of the potential danger at low head dams seems to be the key to avoiding tragedy. A similar experience has occurred at Bow River Weir in Alberta, Canada. After completion in 1975 eight people drowned over the next seven years. Dam managers took a number of steps which included installing a multi-layered warning system using different kinds of graphic signs. The primary objects of the project are to enable river passage for non-motorized boats and enhance fish passage while maintaining water supply functions.

The hydro and dams industry in the west faces the challenge of demographics and aging facilities while infrastructure investment takes off for a new generation. The problems are the natural fall-out from long-term cycles of demographics and economics and, consequently, opportunity for both investment and employment. In the north west of the US, Seattle City Light (SCL) will see about half its employees eligible to retire in five years or less. Work is underway on succession planning concepts to address the challenge of this human wave of leavers with so many skilled and experienced personnel. SCL is exploring how best to involve the local communities as much as possible, given that the infrastructure is part of the socio-economic fabric and many individuals may seek opportunities to continue to live and seek work near to where they have grown up, or have been working so far.

The US Army Corps of Engineers is undertaking dam safety training in a virtual university environment to allow retiring engineers pass on their expertise to younger colleagues in this unique program. After earning both his bachelor's and master's degrees in civil engineering at the University of Puerto Rico at Mayaguez, Sanchez joined the USACE New Orleans District in 2008, where he worked on the Hurricane and Storm Damage Risk Reduction System. The Dam Safety University is one of the ways in which USACE is implementing succession planning, since many of its dam safety engineers are nearing or have reached retirement age. Assignments in the Dam Safety University program are filled internally and competitively, and interest is growing. Through this unique program, team members gain valuable professional development and the Corps gains sustainability for its dam safety program.

Patrick Reynolds reports how large and small hydropower developments are pushing ahead across Latin America with much cross-border and wider international participation. Projects completed in the last couple of years include: the 241MW Sao Salvador scheme on the Tocantins River between the states of Tocantins and Goais in the north of the country, and developed by a subsidiary of GDF Suez; and the 140MW Baguari plant, which was constructed in the mid-west state of Minas Gerais. Belo Monte will be Brazil's largest hydropower scheme entirely within its borders, and is far larger than the two sister projects that also caught the imagination of the sector in recent years - Jirau and Santo Antonio, in the west of the country. The project comprises two powerhouses - the 11,000MW main facility and a secondary station of 233MW that will be equipped with Francis and bulb turbines, respectively.

The US Government has a range of support initiatives in place to help conventional and new types of hydro development to help boost renewables. In April, DoE and DoI announced $26.6M in R&D funding for advanced conventional hydropower and pumped storage projects. Letters of intent were sought by May ahead of full applications to be submitted early this month. A year after the MoU was signed, the DoI released a report on the hydropower potential at 70 of USBR's facilities that said an extra 1008 GWh of electricity could be generated annually. While, in terms of scale, the total contribution from the likes of new or extra capacity at existing USBR sites will not tip the balance, projects at such sites would be part of a wider strategic undertaking.
