You're shorting yourself if you only focus on pike -- salmon season should be in, browns will be hungry and crusing, char should still be shallow enough to fish to in the lakes (particularly if you head north a bit or go up on the plateau)...
Oh, don't worry - I will be throwing to anything that swims and throwing it anywhere I can get to! They key advantage, though, is that this lake and 2 streams are within walking distance, or at the least a very short drive! It appears there are several boats on the property too!
We will be near Torberget, which is about 50 miles east of Lillehammer. Do you know that area by chance?
