I'm not an expert on hydro power, so I'm trying to imagine what some of these scenarios are. Earlier you mentioned fish going through a turbine, which I think is a pretty visual way for a fish to die, but obviously we're also talking about other kinds of impacts related to these activities.
We mentioned the analogy of the wildlife overpass. There must be analogous mitigators in the hydro world. Is it simply a matter of those mitigators being too expensive for your industry to afford? Perhaps unpack that a little for us.
