In Minnesota, where bass fishing is closed until late May to protect the spawn we have a different starting point then our southern fishing brethren. Pre-spawn is a time when fishing is fast and furious, and fish in this stage can be found and targeted even in early June, if you know where to look. Most natural lakes have areas which just don't warm as quickly as the rest of the lake. Sandy bottoms, deep shorelines, wind-swept eastern shores. Look for smaller areas which offer ideal spawning areas, after the spawn has occurred in other parts of the lake. You will find fish still moving in, aggressively feeding and not yet on the beds in these areas. The best areas have boat docks and pilings for docks not yet put in for the year. Target these areas now, rather than trying to catch fish off beds in the warmer parts of the lake.
