Canadian settlers began using the St. Mary River as an irrigation source in late 1800’s

American settlers began using the Milk River

Resource scarcity When the Milk River’s unreliability threatened the stability of the region, the US made plans for a canal and dam to divert St. Mary River water into the Milk River for use in Montana

Canada became concern Early 1900s - Alberta built a “spite canal” to show that it could siphon water diverted from the Milk River back into the St. Mary River further downstream.

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) data

21
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 SOS

22
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.
