My Question - I have not followed this too closely, but in the articles I've read I've only seen it mentioned that they are treating the streams twice with rotenone. If they really want to do a thourough job, I'd think they would shut down the lake and treat it several times, "just to make sure", as well as a continuous treatment of any inflow...
I don't think it would take too long to get the aquatic food chain back in order for the next planting (prior to ice-over). Nature has a way of replinishing itself...
