I'll make one point on that. One of the biggest threats is that our overall flow in the navigable waterways is changing rapidly, and it comes back to what Jay was talking about earlier. Because of climate change, we have a much more fluctuating base flow and runoff cycle. Without having control and being able to manage those waterways now, I think that people will be at risk of not knowing exactly when it'll be safe to navigate them, what's coming up, and what should be expected—flood conditions versus very low-flow conditions.
Your point is probably really well taken: that as we move forward now with climate change potentially impacting these flows, it's even more important than it was before.
