This video describes how non-functional dams and poorly-maintained or undersized culverts pose a risk of major flooding and infrastracuture damage, and how they act as barriers to fish and other species moving upstream to spawn or migrate.
It highlights the removal of obsolete dams and the replacement of problematic culverts along tributaries of the Hudson River in New York and is 5 minutes and 50 seconds long.
This video provides historic examples of disasters caused by dam failures.
Students learn about the efforts to restore fish habitats and reduce flooding risks.
Additional Prerequisites
Students may better grasp the importance of these efforts if they understand fish migrations, why they travel these distances, and what it means for their ability to survive.
Differentiation
This is video is a great resource for students to watch before a field trip to a river, helping them identify similar cases and issues in real life.
Students can also study the Hudson River Valley map, identify different tributaries of the Hudson River, and investigate if any of them face similar challenges. Students can then present their findings to the class or in a paper or report.
History or social studies classes can use this video to connect to the industrial past of the Hudson River Valley or other similar locations.
Connect this video to the topic of climate change by discussing the more frequent extreme rain events of the last 30-40 years and how they are connected to the water cycle, the ability of warmer air temperatures to hold more water vapor, and changing weather patterns.
