Pine Flat Lake is 30 miles outside of Fresno, Ca go HWY 180 to Clovis and Belmont, turn left on Belmont it turns into Trimmer Springs rd passed Piedra, keep to the left every time the road y's. and you'll be at the lake in no time. It's a great lake for bass fishing, salmons, blue gill, trout of different types. I found a nice spot up there with a long boat launch and motel/cabins so i don't need to sleep in my truck anymore.
Hope it helped for a location.
