Episode 120 – A Stork Visits: Rebroadcast “Dam Nation”

Shannon just had a baby! We take the week off and celebrate with this classic episode of the geocast… Don’t Panic, we’ll be back next week!

Having just got back from vacationing near a river, Shannon’s mind is wondering (and wandering!) about dams and their impacts, both good and bad. People use dams for electricity, recreation, flood control, and a myriad of other things. Let’s take a look at some huge dams and what they do to both communities and rivers.

Why build dams at all?

  • Water supply
  • Irrigation and flood control
  • Power supply
  • Recreation

Hydroelectric Power

  • Hoover dam generates 4.5 billion kw-hr per year, serving 8 million people in AZ, southern CA and NV
  • Itaipu dam, on the border of Brazil and Paraguay, dams the Parana River, the 7th largest in the world.
  • Penstock

Episode 114 – “Charismatic megafauna” with Shane Loeffler

What is “flyover country”? Is it the states in the middle of the US? A band name? A geoscience education app? One of these is true and the creator joins us to chat about it. A big thank you to listener Gary for pointing us to this topic!
