[quote Dunn13]How long do you have to wait after the rotenone treatment until it can be safely stocked again?[/quote]
Very quickly. Rotenone naturally breaks down when exposed to light and oxygen. Temperature plays a large factor in the breakdown as well. At higher temps (80 degrees) it will break down in a few days. At cooler temps (45 degrees) it may slow to a few weeks -- which is why they have the lake closed until Oct. 31.
They also utilize detoxification stations to prevent the rotenone from affecting non-target waters. For example, outflows. Rotenone can be neutralized using Potassium Permanganate. This is how fisheries managers are able to poison specific stretches of streams, when necessary.
