Look for a boulder-strewn point that has a series of dropoffs to deeper water, rather than a gently sloping point without bottom cover. Rocky points provide food and cover for baitfish, which in turn attract lakers. During low-light periods, fish right up on the point. Concentrate on deeper sections or edges during the day. Many anglers ignore them, yet some of my best spring catches have come from the massive sand beaches at Wasaga Beach on Georgian Bay and Sandbanks Provincial Park on Lake Ontario.
Sand soaks up the sun's rays, quickly heating the water.
I recall the first time I fished for spring lake trout. Having fished the lake for nearly 40 years, he knew every key trout-holding point, shoal, and beach like the back of his hand. Heck, I didn't even have that much on my old spinning reel. Anything less in shallow water increases the chances of spooking fish. Motor noise is the greatest problem, but so is a boat's shadow, particularly in clear water.
