ii. How does the day to day management of the dams take place?
iii. What is the interaction between the companies and the WLC?
iv. Who makes the decisions on changing flow?
v. How can I understand the flow of water in the basin?
vi. On average. How much water comes into Rainy Lake from Namakan Lake? From other sources?
vii. Where does the water come from which enters the Namakan Chain of Lakes?
viii. What resources are there to better understand the outflows from Rainy River and Rainy Lake and how the flow is managed?
ix. What data and forecasts are used to make decisions?
x. How has dam regulation affected Rainy Lake and the Namakan Chain of Lakes?
f. High Water Issues
i. If there are dams controlling flows out of both lakes, why does high water still occur?
ii. Why aren’t more gates opened sooner when water levels are rising on Rainy Lake?
iii. Since the outlets of Namakan Lake and Rainy Lake can’t pass enough outflow at lower lake elevations to avoid high water in a wet spring, doesn’t it make sense to enlarge them so this isn’t a problem?
iv. When winter snowfalls are deep and melt late, why aren’t the dams opened early on to make room in the lakes for all of the water that is coming?
v. Doesn’t knowing the snow pack provide a reliable indicator of the water supplies for the spring and summer season?
vi. Are there people or organizations that could provide better forecasts?
vii. There are a number of dams beside those at the outlet of Namakan Lake that can help control the flow entering Rainy Lake. Did the IJC look at reducing flow out of other control structures and dams during the high water
period? If not, why not?
viii. Since the 2000 Rule Curves came into effect, there have been many high water years on Rainy Lake. Why is this?
ix. There have been more high inflow years in the last 15 years than previously. Is this due to climate change? If so, what can be done to prevent high water events in the future?
x. How did Rainy Lake outflow affect high water on the Rainy River and its tributaries in 2014?
xi. Why are the turbines in the powerhouses at the Rainy Lake dam designed so that they can’t operate at full capacity under extremely high water conditions such as the summer of 2014? Can’t they be fixed?
xii. The flooding of the Boise turbine room was a problem back in 2001. What was the problem in 2014?
xii. Water went over the spillway at the Fort Frances—International Falls dam in the summer of 2014 for the first time since 1950. Is this dangerous or damaging to the dam?
