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.

• Oroville (1968) is the tallest in the US, and earthen dam in CA 770′ high
• Hoover (1935) is next at 726′ high on the border of AZ and NV
• Tallest dam in the world is Jingping-I dam (2013) in China is 1000′ high
• Largest reservoir in the US is Lake Mead, which holds 29 million acre-feet of water
• Glen Canyon dam
• Lake Powell on the AZ/UT border, and is a close second at 26 million acre-feet capacity.
• Colorado River
• WPA

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
