Started trolling to learn this lake. I trolled the south west side revealing a shallow mid lake hump about twenty to thirty feet from shore. Around the southwest side of spanaway bass were aplenty, but with such abundant weed growth, your methods are limited to top waters, spinnerbaits, plastics, minnowbaits or Jigs. Several holes in the SW cove for still fishing for trout and panfish. In many places of the south end, weeds grow up 16 feet in 20 feet of water. I figured the whole south third of the lake would be dynamite in spring and winter, and best left alone in summer and fall till the weed growth dies off. The north side of the Island showed masses of baitfish on the fishfinder, along with Smallmouth bass feeding all over on top along with some brute stock trout rolling all over. It was fish roll city there as top waters took care of the bass. Flies will catch the trout and beware of several humps in the NW side of the island which are dangerously shallow for larger boats.
Bass seem to be feeding off the rocks for crayfish and will take crankbaits readily for a meal. Fat raps or cranks with a lively wobble that resemble crayfish are best. Bass (fingerlings) from last spawn are about 3 inches in length, or the same size as crayfish so you cannot go wrong with crank baits this time of the year. Search out areas around the Island as well. Trout seem to be in the deepest part of the lake which falls in the south side of the Island due to the preferred colder water temperature, so troll a loop there to get in on some large trout. Be curtious to the home owners and there docks and property. We had trouble from skiers and speedboats of people who live on the lake. I guess they figure it is there lake and they can do just what they want to do. The fish are there, you have to find them and present them with an offering they can't refuse. We did well and hooked into the bass of a lifetime that had a mouth as big as a gallon jar! It snapped ten pound test as if it were thread. We know we will be back, good luck anglers
