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
- Water supply
- Irrigation and flood control
- Power supply
- Recreation
- 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
Write us a geoscience themed limerick! This is a family show, so remember…nothing that rhymes with “Nantucket” Please email us your limericks by August 12, 2016 and we’ll be judging them along with Dr. Katie Schearer, an english professor.
