Mini Quiz ! • What % of the Earth’s surface is covered by water? • 70% • What % of water is accessible for human use? • 3% is freshwater, 2.4% is frozen or deep underground, so less than 1% is accessible • On average, how many litres of water does a Canadian use each day? • Between 329 to 343 litres

  2. Presentation Overview • Water in Canada • The Hydrologic Cycle • What is a Watershed? • Our Watershed • Brief History • Water Colour • Pollution • Endangered Ecosytem • Tidal Bore • Tidal Bore in the Past • Tidal Bore or Total Bore? • Tidal Bore Photos • About us • Our issues • Take Action

  3. Water in Canada http://www.ec.gc.ca/water/images/info/facts/e-Canada_domestic_water_use.htm

  4. The Hydrologic (Water) Cycle http://www.ec.gc.ca/water/en/nature/grdwtr/e_cycle.htm

  5. What is a Watershed? • Watershed: A watershed is an area of land that drains surface water from a connected system of watercourses and that ultimately drains into one particular river, creek, stream, lake or ocean. http://www.tetes-chercheuses.fr/images/img45e68f6cb8362.jpg

  6. What is a Watershed? • Watershed: The watershed includes both the streams and rivers that transport the water, as well as the land surfaces from which water drains into the watercourses. http://geoscape.nrcan.gc.ca/h2o/bowen/images/watershed_e.jpg

  7. Our Watershed • Here is our watershed http://www.petitcodiac.org/riverkeeper/francais/La_Petitcodiac/Bassin/bassin.html

  8. Brief History • Geological formation of this region dates back to more than 250 million years ago • What is the Mi’kmaq name for the Petitcodiac River and what does it mean? • First Nations named it Pet-Kout-Koy-Ek which means River that bends like a bow.

  10. Brief History • There was a thriving shipbuilding industry in the 1850’s • What important species was commercially fished before the constructionof the causeway? • Commercial Atlantic Salmon fishing exceeded 2000 kilograms per year, from 1960 to 1967 • Population decline between 1967 and 1968 to a mere 668 kg harvested

  11. Brief History • In 1968, a causeway was built…

  12. Brief History • From 1968 to 1992, Moncton’s dump was located on the shores of the Petitcodiac • Moncton’s raw sewage was discharged directly into the river until Greater Moncton’s sewage treatment plant started operating in 1994 http://maps.google.ca/maps?hl=fr&ie=UTF8&ll=46.068973,-64.808221&spn=0.016763,0.034676&t=k&z=15

  13. Water Colour • What causes the brown colour of our river? • The Petitcodiac River’s colour is due to suspended sediments. • These sediments come from the silty banks of the river. • The silt remains suspended because of the waves current, tides, wind etc… • There is no direct link to the color of water and toxic pollution

  14. Pollution What are some examples of water pollution? • Pesticides • Abandoned Dams • Toxics in the air • Acid Rain • Toxic Waste • Causeways • Landfills • Wastewater • Sedimentation • Snow Dumps • Stormwater • Chemicals

  15. Endangered Ecosystem • Changes in the Petitcodiac ecosystem, affect ecosystemsthousands of kilometersaway (Arctic, American East Coast , South America, etc.). • All ecosystems are linkedtogether, one way or another • So this is why we don’t want to pollute our watershed and use too much water… http://www.glf.dfo-mpo.gc.ca/os/bysea-enmer/images/img_food_web_mod5.jpg

  16. Tidal Bore • The tidal bore is created by the great Bay of Fundy tides • The front of the bore is the tide coming in • Rare natural phenomenon • Visit Youtube and type in: • Tidal Bore • Amazon Surf

  17. Tidal Bore in the Past • Up to 2 metres high • Heard from more than 1.5 kilometres away!

  18. Tidal Bore or Total Bore? • Today, it can be as high as 75 cm traveling at speeds up to 13 km/h • Since Petitcodiac Causeway construction, the tidal bore lost its strength

  21. About us • Not-for-profit organization • Member of the Waterkeeper Alliance • Goals: • To restore and protect the ecological integrity of the Petitcodiac River system • To ensure compliance with environmental laws • To educate the public about our river and pollution issues

  22. Our Issues • The causeway has been our main issue since the start of our organization in 1999 • The gates will open in 2010, but… • We must ensure the project is completed • Other issues needing attention: • Uranium • Pesticides • Sewage • Abandoned dams and other causeways

  23. Take Action • What can you do? • Reduce water use • Be informed • Get involved • Respect our environment and our river • Become a volunteer • Contact us at info@petitcodiac.org

  24. Thank You! • Thanks for your time
