The eastern end of Lake Erie is clogged with ice that is pushed against the shoreline by the prevailing westerly wind. The ice collects in Lake Erie, and the Lake Erie-Niagara River Ice Boom prevents it from flowing down the Niagara River, which is the international boundary between the Canadian Province of Ontario, and New York State. A boom is deployed each December. Operational since 1964, the boom serves several functions: it protects the water intakes for the Niagara River power plants, and it minimizes ice runs (large blocks of ice flowing downstream as ice breaks up in the spring) and blockages that can create damage and flooding along the river.
Astronaut photograph ISS014-E-17999 was acquired March 21, 2007, with a Kodak 760C digital camera using an 180 mm lens; astronaut photograph ISS015-E-5624 was acquired April 29, 2007, with a Kodak 760C digital camera using an 180 mm lens. Both images are provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Laboratory, Johnson Space Center. The images in this article have been rotated and enhanced to improve contrast. The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth.
