Wading doesn't work at pymie...
...
but if you're just looking to wet a line & get cold....
Look for the shallow points that extend into the lake. Find one with gravel.
The will be some sediment too, it's not like pure washed stone, but you'll feel the gravel as well.
The points close to inlets ~ even small ones ~ seem to have the most action, although not always the biggest fish.
There are many, many, good points to wade.
If my favorite spot is crowded (more than 3 people), I just move down the lake until I find some elbow room.
