This blog post describes how the Colorado River was once again able to reach the Sea of Cortez after sixteen years of not reaching its final destination. It discusses a reason why the Colorado river no longer reached the Sea of Cortez and impacts of the changes to Colorado River flow and the estuary.
Teachers could pose the following questions:
What impacts could sustaining this flow of water have on the estuary and fish populations in the Sea of Cortez (Gulf of California)?
Why were dams created along the Colorado River?
What happened to the estuary after dams were created along the Colorado River preventing it flowing into the Sea of Cortez?
