  4. 4. Canadian settlers began using the St.Mary River as an irrigation source in late 1800’s http://en.wikipedia.org/wiki/File:LevelBasinFloodIrrigation.JPGOGC ® © 2013 Open Geospatial Consortium 4
  5. 5. American settlers began using the Milk RiverOGC ® © 2013 Open Geospatial Consortium 5
  6. 6. Resource scarcityWhen the Milk River’s unreliabilitythreatened the stability of the region, theUS made plans for a canal and dam todivert St. Mary River water into the MilkRiver for use in MontanaOGC ® © 2013 Open Geospatial Consortium 6
  7. 7. Canada became concernEarly 1900s - Alberta built a “spite canal”to show that it could siphon waterdiverted from the Milk River back intothe St. Mary River further downstream.OGC ® © 2013 Open Geospatial Consortium 7
  8. 8. And on and on …• …• 1909 Boundary Waters Treaty – The two rivers should be treated as one for the purposes of irrigation and power – …OGC ® © 2013 Open Geospatial Consortium 8

  21. 21. Assessment of Nutrients Loading for Great Lakes (US and Canada)• Integration of Great Lakes water quality data for US and Canada – USGS and EPA Water Quality Portal services – Water Quality Exchange (WQX) dataOGC ® © 2013 Open Geospatial Consortium 21
  22. 22. Assessment of Nutrients Loading for Great Lakes (US and Canada)• Integrating with stream flow (calculating nutrient loads) – Locate and associate water quality monitoring stations for a selected point of interest in the Great Lakes – Retrieve nutrient values for identified upstream stations using SOSOGC ® © 2013 Open Geospatial Consortium 22
  23. 23. Assessment of Nutrients Loading for Great Lakes (US and Canada)• Integrating with stream flow (calculating nutrient loads) – Use WPS to calculate nutrient loads for the requested time period •  Execute a simplified nutrient load calculation model based on USGS Exploration for Graphics for River Trends (EGRET) for selected nutrients.OGC ® © 2013 Open Geospatial Consortium 23
