Assessing the Condition of your Dam Face

Dam

What may be out of sight should not be out of mind.

Keeping underwater assets in good condition is a huge part of dam safety. Collecting underwater data and working in underwater environments can be a challenging undertaking. It requires specialized equipment to assess the condition of your dam. Personnel experienced in conducting underwater investigations is also important.

To make informed decisions, collecting quality data is key. With specialized technology and an experienced team to accurately interpret data, accurate and repeatable underwater data collection can be achieved.

There are many factors that can affect underwater data resolution and accuracy. The choice of sensor among many other variables can influence the data collected.

Fun Facts About Dams

Did you know in Canada, there are more than 14,000 dams? Roughly 1,000 of them are categorized as “large” dams. These are registered with ICOLD, the International Commission on Large Dams. Although there is no federal regulatory agency providing requirements to guide the safe management of dams, it is involved in some areas. The approval of dams to be constructed in navigable waters, dams located on boundary waters with the US, and dams constructed and operated by the Canadian nuclear industry (Nuclear Safety Commission), to name a few.

The US has 6 times the number of dams in Canada (84,000). In the US, the federal government is responsible for maintaining the safety of federally owned dams.  FERC, the Federal Energy Regulatory Commission, regulates hydroelectric projects in addition to the natural gas industry, electric utilities and oil pipelines. In relation to hydropower, the Commission issues licenses for the construction of new projects, re-licenses existing projects, and provides oversight of all ongoing project operations including dam safety.
