No, we don't extend into Lake Athabasca itself. We look at the Athabasca River, primarily, but the Clearwater River as well.
What was mentioned earlier, though, was that there are a lot of migratory fish species that tend to use the river from the lake, so we have captured or have reported recaptures on the tagged fish from the far north--Slave River and the Athabasca lake itself.
So we don't look at the lake per se, but the fish that inhabit that lake use the rivers in certain parts of their life cycle. We catch them then and look for fish health and any abnormalities that we find there.
