World's waters

Minsk answers to our questions:

Svisloch starts on the Minsk height on the main European watershed, in 39 km to the northwest from Minsk.
In Svisloch a lot of of small rivers and streams run, the largest of which is Volma and Talca, in the territory of Minsk it's Nemiga, Loshitsa and Slepjanka.
In 1976 it is connected to the river Vilija (pool of Neman) by means of the Vilejsko-Minsk water system therefore it level of water in upper courses has increased in tens times. The average expense of water in 88 km from a mouth 24,3 m3/seconds It freezes usually in December, is opened in March — the beginning of April.
On Svislochi the city of Minsk and the Osipovichsky HYDROELECTRIC POWER STATION largest in Belarus are located. In the past it was used for a fishing craft, navigation and a timber-rafting, now has the limited recreational value. In Minsk and below it on a current the river is strongly polluted municipal and by industrial wastes It is used as a source of technical water supply of the enterprises of Minsk.

1. Where I live we get our water from the Georgian Bay or wells. Sometimes people get there water from water stops because they think its cleaner water, we are one of those families.
2. Most families use there water for drinking, bathroom things like brushing teeth, and we use water to clean things like clothes, cars etc.
3. Behind my house there are two wells that supply water for the entire area. The area I’m talking about is called peek-a-boo trail. It’s a small dead end road that branches off into a subdivision; the total amount of people here is around 150-250. For the town of Penetanguishene there is a water tower and people to far from the tower get water from the water treatment facility.
4. As far as I can determine there has never been any draughts in Penetanguishene because of our closeness to such a big body of water.
5. Each animal such as a pig or cow on a farm uses a general amount of 80 litres of water in a day. Assuming there are 50 animals on the farm, it would use around 4,000 litres of water in a day.
6. In Penetanguishene and Midland there are about 23,000 people and every person uses an average of 130 litres of water per day. Therefore, that average daily use of water in my town is about 2,990,000 litres.
7. Site 41 – a proposed dump that will sit on top of a pristine artisan aquifer containing some of the purest water in the world. In December, the Ministry of Environment approved a water taking permit that could see the aquifer drained by the time the earth thaws this spring. “This garbage dump is a form of eco-genocide,” says environmentalist Danny Beaton. “Wolves, rabbits, deer, fox, raccoon, eagles, ducks and all life are drinking the sacred waters of Georgian Bay aquifers. The aquifers and the waters of Georgian Bay do not belong to us – they belong to our children’s future. And it is our responsibility as adults to protect our children’s future.”
An Essay
Georgian Bay - Georgian Bay is surrounded by Manitoulin District, Sudbury District, Parry Sound District, Muskoka District, Simcoe County, Grey County and Bruce County. Georgian Bay is about 320 kilometers (200 miles) long by 80 kilometers (50 miles) wide. There are tens of thousands of islands in Georgian Bay. Most of these islands are along the east side of the bay and are collectively known as the "Thirty Thousand Islands," including the larger Parry Island. Manitoulin Island, lying along the northern side of the bay, is the world's largest island in a freshwater lake. The towns of Midland and Penetanguishene, at the southern end of the bay, are a popular site for summer cottages, as are the many bays and islands on the eastern shore
Legend of Kitchikewana:
Huron legend tells of a God called Kitchikewana, who was large enough to guard the whole of the Georgian Bay. Kitchikewana was known for his great temper and one day, in a fit of rage, he dug a giant hand into the ground and flung the dirt he pulled up into the Great Lakes. Thus, the 30,000 Islands were created. The indentations left behind by his fingers form the five bays of Georgian Bay: Midland Bay, Penetang Bay, Hog Bay, Sturgeon Bay, and Matchedash Bay. He then lay down to sleep and sleeps there still as Giant's Tomb Island.

The USA, Seattle ( Andrew, Ian , Mantas)

The Cedar River water shed supplies fresh water to 1.4 million people. The watershed covers 90,638 acres and is owned by the city of Seattle. The Tolt River watershed supplies 30% of the water to the people of Seattle. It also supplies water to 1.3 million people.

In Washington water is used for making electricity. The Columbia River provides us most power because the Columbia River has many dams that pump water through them and give us a lot of electricity.

Seattle water is so clean that it doesn’t require filtration. For safety reasons though, it is disinfected. But when the algae blooms it might make our water smell or possibly have a bad smell to it but generally it’s not of concern. If you have a faucet purifier you my also notice that it get more clogged up during this season even so we have solved this problem by opening facilities that clean it out. One other problem is people trying to poison the water, so we have good security to protect it.

People in Seattle use about 100 gallons a day and factories and farms use about 1.42 billion gallons of water.

Puget Sound is a large salt water estuary(a place where salt and fresh water meet; usually filled with all kinds of life) that was created by ancient glaciers from the ice age. Before the glaciers dropped the water on the area, there were no lakes or rivers supplying it. Today, the Puget Sound is provided by a number of sources. Rain around the area, rivers, melting ice and water from the ocean. As you can see from the picture on the right, the Puget Sound is at the very edge of the advancing glaciers during the Ice Age and got a lot of melting water during the summer.

Puget Sound holds a variety of sea life, one of the most abundant and most popular are salmon. Since Puget Sound is defined as an estuary it can support an extensive collection of this type of fish, along with this fish there are also geoducks, seals, and most important to the ecosystem, plants. Puget Sound also holds collection of plants that include some coral reefs.

Learning Circles January-May 2009 Session

This time my students and I are making a research on the topic "The world's water". Join our group and tell us about your river or lake.

Here they are - 8a class
Every day the demand for water grows. How does your family use water? Are you 'water wizards' or 'water wasters"?

These are our rivers: the Vychegda and the Kia-yu
