Adams has had a long history of flooding due to the Hoosic River. As shown below, the river, with its bending course through town has caused many instances of destruction resulting in the US Army Corps of Engineers building a series of stone and concrete structures to protect the town's infrastructure from further damage during a rise in the river's water levels. While this has resulted in less flood damage, it did bring with it other issues that remain today. In fact, in North Adams, where a similar plan was implemented, there are now discussions being had about removing some of the concrete chutes.

While the flood control project did help with reducing flood damage, it did create areas on the river that potentially can be hazardous or even deadly. When the chutes are flowing large amounts of water there are areas where hydraulic jumps can occur. These "spillways" or "drop structures" can, under the right conditions, have the same characteristics of low head dams, a structure often referred to as "drowning machines". It is imperative that we, as first responders know what to look for and how to stay safe around such dangerous areas.

Shows how the jumps can become dangerous
detailed modelling showing the different jumps
good overall explanation with real-world fatal incidents
If called to one of these areas, it is imperative to understand the danger that can be present when formulating a plan of action. As shown above, even highly trained rescuers can quickly become victims if the proper techniques and materials are not implemented.
Further water hazard training will be upcoming.
