That is a great point Toolman. While we are at it, I'd like to throw out the idea of putting restrictions for water flow change to be a certain percentage of the flow rate per hour (something like 10-20% perhaps?). This would hopefully alleviate those sharp spikes or drops in water flow we tend to see on the Bow River. I do not have any knowledge of how the dams work, but there must be some way to gradually lower the water level, rather than drop it significantly for a couple hours then pop it right back up.
