Hello,
I am not sure where you are planning on going on Nipissing ie: South side (North Bay , Callander) or the Northern side Sturgeon falls area but if you are looking for bass, pike, musky I would say stick to to the Sturgeon falls side... I know Glenrock Cottages is on the lake and they have boats, mainly 16' cedar strips but they handle the Nip water well. The reason I say stick to this side is the pike fishing is by far the best in Cache Bay which would be about a 5 min boat ride from glenrock or the mouth of the Sturgeon river. You can catch pike all day long in this bay, all the pike tournaments are mainly held here. Look Cache bay up on the map you wont be disappointed, the whole bay ranges from 2' to maybe 10' and it is packed with weeds.... You will definatley know when you get into the bay as you will be cleaning your prop off regularily. For musky you can go to the top portion of Cache bay near the mouth of the Veuve river and even into the Veuve, I have landed some very nice ones in there. As for bass , you will see alot of rock markers and islands on the way to Cache bay and any of these rocky spots produce large Smallies. Also if you ever are interested in going out for Walleye by best buddies Dad is a guide and I could set you up for a half day or something, I dont know what he charges but he has a sweet boat and he has been fishing the lake for 30 years.
Hope this helps, any questions let me know.
